Introduction
System Features
General Description
The Telex RadioCom™ BTR-800 UHF Synthesized Wireless
intercom systems offer the ultimate in reliable,
high-performance, high-fidelity full-duplex communications.
Frequency-agile base station and beltpacks. No external
computer/device required to select frequencies.
•
•
Backlit base-station LCD allows the user to easily moni-
tor the beltpack’s status as well as change base-station fre-
quencies.
The BTR-800 system includes the BTR-800 frequency agile
base station, working with up to four TR-800 or TR-825 fre-
quency agile beltpacks. The BTR-800 base station provides
full-duplex communications with the beltpacks.
ClearScan™ function on base station and beltpack to au-
tomatically find the best channels on which to operate.
•
The BTR system incorporates two audio channel operation,
permitting the beltpack operator to choose between two sepa-
rate audio channels of communications, with the base station
tracking the beltpack selection. This allows the user the flexi-
bility to create a party-line and a private line within the same
beltpack.
Full-duplex (simultaneous talk and listen) operation.
•
•
Compatible with Audiocom® (Telex), RTS TW, Matrix,
Clear-Com® , and other wired intercom types.
Two channels of intercom audio.
•
•
The BTR-800 system is perfectly suited for stand-alone opera-
tion and also can interface with Audiocom® (Telex), RTS®
TW, Clear-Com®, as well as RTS Matrix systems and other
4-wire communications systems. In addition to the external in-
tercom systems interfaces listed above, the system provides
connections for auxiliary balanced audio input and output, as
well as wireless talk-around (WTA) and stage announce (SA)
features.
WTA (Wireless Talk Around) beltpack control. This fea-
ture allows beltpacks to talk to each other, but their audio
is lifted from any wired system connected to the base sta-
tion.
SA (Stage Announce) beltpack control. Allows the user to
direct their audio to a jack on the back of the base for P.A.
systems or other external audio systems.
•
The RadioCom™ BTR series has been designed for reliable,
efficient operation. Operating in the 470 to 740 MHz range,
the units operate reliably at line-of-sight distances of 1,000
feet. With available antenna systems, from Telex, the effective
operating range can be extended. The high-efficiency
beltpacks provide up to 12 hours of uninterrupted operation
using standard alkaline batteries.
Relay contact closure on the base when the SA button is
pressed.
•
•
•
•
TR-825 features two audio channel binaural operation in
either stereo or mono mode.
Beltpack units contained in a weather and shock resistant
die cast magnesium case.
Convenient IEC power connector on the base station so
the unit can plug directly to outlets. No in-line or wall
plug power supply.
Base station comes with rack ears for easy rack mounting.

5. Bat/Overmod Light (BAT/OM) – Light will flash once
when unit is turned on if the battery is good. If the light
stays on, battery is low. If the light does not flash, battery
is dead. A normal microphone gain setting will cause the
LED to flash at the beginning of most words at normal
speech levels. If the gain is too high, the LED will be red
during the complete word at normal speech levels.
2. Wireless Talk Around (WTA) – When pressed, the user’s
audio is disconnected from the wired intercom, auxiliary
input/output and the base station’s local headset. Other
beltpack users, on that audio channel, can hear the user as
normal. The button activates the nearby red LED as well
as the “TALK” LED, #6, when pressed.
6. Talk Light – LED is on when the talk button, SA or WTA
is active.
3. Stage Announce (SA) –When pressed, the user’s audio is
routed to the stage announce connector on the back of the
base station. The user also loses their sidetone as an indi-
cation that stage announce is activated. The other wireless
beltpacks and wired users do not hear the user’s audio.
The button is non-latching and activates the nearby red
LED as well as the “TALK” LED, #6, when pressed.
7. Talk button – Press to enable the audio path from the lo-
cal headset microphone. The “TALK” LED, #6, will turn
red when enabled. A quick press and release latches the
talk function, unless latching has been disabled. Holding
the button for over ½ a second will cause the audio path to
be enabled only for as long as the button is held. If the talk
function is latched on, pressing the talk button again will
turn it off.

1. On/Off and Volume Control - Turns beltpack power on
and controls headset volume for Intercom Channels “A”
and “B”. Either knob, “A” or “B”, turns the beltpack on.
Both knobs must be off to turn the beltpack off. If only
one knob is off, then only that Intercom Channel, “A” or
“B” is off for both transmit and receive audio.
4. Talk Button - Press to enable the audio path to either In-
tercom Channel “A” or “B” or “A + B”, from the local
headset microphone. The associated “TALK” LED, #6,
will turn red when enabled. A quick press and release
latches the talk function, unless latching has been dis-
abled. Holding the button for over ½ second, will cause
the audio path to be enabled only for as long as the button
is held. If the talk function is latched on, pressing the talk
button again will turn it off.
2. Wireless Talk Around (WTA) - When pressed, the user’s
audio is disconnected from the wired intercom, auxiliary
input/output and the base station’s local headset. Other
beltpack users, on that audio channel, can hear the user as
normal. The default setting is software selectable, as to
which Intercom Channel, “A”, “B”, “A + B”, or currently
selected channel, is activated along with the “WTA” but-
ton. The “WTA” button activates the nearby red LED as
well as the software selected Intercom Channel “TALK”
LED if not already active.
5. Low Battery/Overmodulation (BAT/OM) Light - Light
will flash once when unit is turned on if the battery is
good. If the light stays on, battery is low. If the light does
not flash, battery is dead. A normal microphone gain set-
ting will cause the LED to flash at the beginning of most
words at normal speech levels. If the gain is too high, the
LED will be red during the complete word at normal
speech levels.
3. Stage Announce (SA) - When pressed, the user’s audio is
routed to the stage announce connector on the back of the
base station. The user also loses their sidetone as an indi-
cation that stage announce is activated. The other wireless
beltpacks and wired users do not hear the user’s audio.
The button is non-latching and activates the nearby red
LED.
6. Talk Light - Will turn red when enabled by associated
“TALK” or “WTA” button.

ANTENNAS SHOULD BE VERTICAL
Attach the transmit 1/2-wave antenna to the antenna input re-
ceptacle labeled “Transmit” on the right side of the rear panel.
The antenna should be vertically aligned.
Figure 12
Vertically Polarized Antennas
Distance between Antennas
The distance between the base station’s receive and transmit
antennas is not adjustable when the antennas are connected di-
rectly on the back of the unit.
The antennas can be remoted for better signal path. A Telex
coax assembly with remote antennas may be required. See
"Accessory" section fr ordering information.
NOTE: If your base station is to be located in a shielded rack
mount enclosure or other poor RF location, you must remote
the 1/2-wave antennas with coax assemblies. See "Accessories
and Replacement Parts" section for remote mounting hard-
ware.
Figure 10
Attaching Transmit 1/2-Wave Antenna
Antenna Placement
Proper antenna placement probably has the most effect on
your TELEX Wireless Intercom System’s overall perfor-
mance. The following suggestions will result in optimum per-
formance.
Attach the receive 1/2-wave antenna to the antenna input re-
ceptacle labeled “Receive” on the left side of the rear panel.
The antenna should be vertically aligned.
Proper placement of the beltpack can be critical. The antennas
should be in the open. Bending the antennas up and placing
the beltpack in a pocket, etc., will reduce system distance.
It is suggested that the unit be worn on the belt or pocket with
both antenna’s vertical for best operating range and perfor-
mance.

The Telex Wireless Intercom System is “Vertically Polarized”.
This means both the transmitting and receiving antennas
should operate in the vertical position.

Keep the distance between the base station and the beltpacks
as short as possible. The greater the distance, the weaker the
signal. Make sure the “signal paths” between the base station
and beltpacks are unobstructed. You should be able to visibly
locate the base station antennas at all times for best perfor-
mance.
Attempting to operate the wireless intercom system through or
around walls, ceilings, metal objects, etc. will reduce system
range and performance.

Operating System Near Obstructions
DO NOT - mount the base station 1/2-wave antennas on, or
next to metal, such as beams, walls with metal studs, equip-
ment racks, etc. This also applies to the antennas when assem-
bled directly to the Base Station. This will “detune” the
antennas which can result in noise or loss of RF signal at the
Base Station, see Figure 17.

Antenna Placement
Improving Reception and Increasing
Range
Keeping the distance from the base station and beltpack as
short, and unobstructed as possible will produce the most reli-
able performance.
The base station is supplied with two antennas. This should
provide satisfactory system performance in most applications.
System range can be enhanced by remoting the 1/2-wave an-
tennas. The ½ wave antennas are ground plane independent,
so a ground plane is not required for good performance.

Base Station - Rear Panel
Location
Transmit Switches
Locate the base station with the front and rear of the unit ac-
cessible so that switches may be set and connections made.
Place the transmit and receive antennas on the base station.
Make sure the antenna’s color band match the color dot near
each antenna. See “Antenna Information” section for more in-
formation on choosing a proper operating location.
There are two switches located on the lower left side of the rear
panel. The upper switch sets the transmit power levels to high
or normal. The lower switch turns the transmitters on or off.
Transmit Power
Set the power level to normal if using the beltpacks at
close to medium distances (<200 feet, 161m,
line-of-sight) from the base station. Set the power level to
high if using the beltpacks at a distance (>200 feet, 161m,
line-of-sight) from the base station.
Power Connection
Plug the supplied power cord into the unit. The base station has
an IEC power receptacle that accepts 100 – 240 VAC, 50 – 60
Hz. The specific receptacle type is an IEC 60320/C14. The cord
it accepts is an IEC 60320/C13. These cords are common and
available through many retail hardware/electronic stores if the
cord is lost.
On/Off
Set the transmitter switch to on for normal use. In the off
position both base station transmitters are disabled. Set-
ting the switch to off will disable all the beltpacks from
hearing anyone else or even their own sidetone.

Internal Transmit Switches
Intercom Switch
Internal to the BTR-800 are two transmit switches which en-
able a user to turn on or off the two transmitters individually.
See Figure 19 for the location. The top cover of the base sta-
tion must be removed for access. The switch closest to the
front panel controls transmitter 1 (audio channel A). The
switch behind that is transmitter 2 (audio channel B). The de-
fault switch position is to the left if you are facing the front of
the base station. This is the “ON” position for the transmitters.
The RadioCom® wireless system can be interfaced to RTS,
,
TW, Audiocom® (Telex), Clear-Com® RTS matrix and other
intercom (I/C) systems. Set the Intercom switch on the rear of
the unit to the appropriate system and connect the system to
the base station. The two intercom channels on the rear of the
base station have loop-thru male and female XLR connections
for two-wire systems and RJ-11 type jacks for four-wire sys-
tems.
In the normal use of the BTR-800, there is no need to access
these switches. They are used to test the transmitters individu-
ally at the factory.
This switch only affects the two-wire intercom systems. The
functions of the I/C XLRs change depending on the intercom
selected. Please see Section 12 for pinout information of the
different two-wire intercom systems.
Intercom Interface
BACK
Telex (Audiocom®) and Clear-Com® intercom systems re-
quire one cable for intercom A and one cable for intercom B in
order to interface two channels of intercom to the base station.
This interfacing is done through the I/C A and B 3-pin XLR
connectors on the rear of the unit.
RTS TW intercoms only need to connect one 3-pin cable to
one of the four intercom XLR connectors since two channels
of audio are carried on one cable. The intercom switch paral-
lels the four XLR connectors when in RTS mode. RTS chan-
nel 1 is placed on intercom A and RTS channel 2 is placed on
intercom B as long as the RTS TW input to the base station is
wired as in Section 12.
FRONT
Four-wire intercom systems require one cable for intercom A
and one cable for intercom B in order to interface two chan-
nels of four-wire intercom to the base station. This interfacing
is done through the I/C A and B RJ-11 type jacks on the rear
of the unit. See Figure 20 for the pinout of the RJ-11 jacks.

Dual Listen Functionality
They will also have the ability to control the level of the mix
(-4 dB to -24 dB down from main channel). Removing two
surface mount resistors and installing two SPDT switches and
two potentiometer enables dual listen. The parts to be installed
are shown in Table 1. The two resistors on the board to be re-
moved are in Table 2.
The base stations's main audio board has the option of placing
additional parts to enable dual listen. Dual listen allows the
mixing of the intercom channels. The mixing will occur lo-
cally, within the base station, and is only heard on that base
station's beltpacks. The user will have the ability to enable/dis-
able the mix of I/C A into I/C B or vise versa. If you have
TR-825 beltpacks, there is no need to install this base option.
The level of the mix can be controlled at the TR-825 via the
two volume controls.

Auxiliary Input/Output
The output auxiliary audio is also taken from the intercom B
base local headset, beltpack(s), headsets, and any wired inter-
com connected to the base station. A modification document
is available from Telex Communications for those who wish to
modify the base station so that auxiliary input audio is heard
only locally; base local headset and beltpack(s) headsets.
The input and output 3-pin XLR auxiliary connections are for
supplying additional balanced audio into and receiving bal-
anced audio from the base station. The output auxiliary con-
nection only interfaces to intercom B. However, there is an
internal switch to control the routing of the input auxiliary au-
dio. See the "Internal Auxiliary Input Routing Switch" section
of this manual.
Internal Auxiliary Input Routing Switch
The input and output auxiliary audio is global. This means
the input auxiliary audio is placed on the base local headset,
beltpack(s), headsets, and any wired intercom system inter-
faced to the base station. The intercom channel(s) the input
auxiliary audio is placed on depends on the position of the in-
put routing switch.
This switch controls the routing of the input auxiliary audio.
This switch has two positions. The "B" position places auxil-
iary input audio onto intercom B only (default from factory).
The "A & B" position places auxiliary input audio onto inter-
com A and B. Please see Figure 23 for the location of this in-
ternal auxiliary input routing switch.

A relay contact closure is also activated when a beltpack user
presses the [SA] button. The contacts are normal open (N.O.).
Rating: 1 Amp at 24 volts AC/DC maximum. A “Phoenix”
type connector (supplied) plugs into the relay contact port on
the rear of the base station. This connector provides a
screw-type closure for an easy connection to wires.
The stage announce output connector is where audio exits the
base when any of the beltpacks press the [SA] button. The
output is balanced audio though a male 3-pin XLR. The stage
announce output level is set at the factory for 2 Vrms typical
output at rated deviation into 600 Ohms. This should be ade-
quate for most applications. There is an internal level adjust-
ment for this output too. See Figure 26 for the location of the

A cable to accomplish this task is NOT supplied, but can eas-
ily be made with common category 5 (CAT-5) wiring.
This RJ-45 type jack allows the connection of wireless talk
around (WTA) to two base stations of the same frequency
bands. This allows WTA on I/C channel A and WTA on I/C
channel B to be the carried through to the other base station
attached together via this jack.
In fact, the most common 10BaseT ethernet patch cables,
568-B wired cables, can be used to connect bases together.
The required cable is shown below.
WTA channel A and channel B is “contained” within a base
station unless the transmit power is off. If it is off, the WTA
audio is routed through the base station link cable to the other
base that has its transmitters on.
The regular two-wire intercom channels are passed from base
to base via the wired intercom cables and do not require the
base station link cable.

1/4-wave antennas. To attach the two antennas, screw into the
receptacles at the bottom of the beltpack. The color dot on the
screw end of the antenna must match the color dot on antenna
receptacle. The receive antenna screws into the left receptacle
if the beltpack is laying flat with the battery compartment face
up and the antenna receptacles facing you. The other antenna
is the transmit antenna. New antennas can be ordered if de-
sired, see the “Accessories” section.
Insert the headset plug into the XLR connector. See the head-
set pinout in the “TR-800/TR-825” beltpack controls and con-

System Operation
Frequency Plan Overview
System Quick Start
The BTR/TR-8XX has 36 factory defined frequency groups
and 12 user-programmable frequency groups. A Group de-
fines the two base station transmit frequencies and thus the
two receive frequencies on all the beltpacks. A Channel de-
fines a base station receive frequency and thus a beltpack
transmit frequency. A base station receive channel that does
not have a frequency set for it will have a dash to the right of
it on the Group/Channel select screen. Details on setting fre-
quencies may be found in the “BTR-800 Menu Structure” and
“TR-8XX Menu Structure” instructions in this section.
Follow the list below to quickly get a base station and
beltpack(s) operating. When completed the user should have a
base station and 1 to 4 beltpacks up and running with full oper-
ational ability. The base station will be on Group 01A with its
four receivers on channels 01, 02, 03 and 04. Each beltpack
will be on Group 01A with a unique transmit channel number
matching one of the base station receive channels.
1. Plug-in the base station via the supplied power cord and
connect the antennas. The color dots on the base should
match the color rings on the antennas.
Factory-Defined Groups
2. Base station rear panel switches: Transmit power set to
High and on.
The 36 factory-defined groups were carefully chosen to avoid
certain intermod products and various other possible sources
of interference. The Groups are set and cannot be changed.
There is a limited number of channels which can be chosen
from within these groups.
3. Ensure base station rear panel IC switch matches attached
wired intercom system. If used stand alone or connected to
a 4-wire system then IC switch position is Not Applicable.
4. Press [MENU] as powering-up the base station. This will
place it on group 01A and set the receives on channels: 01,
02, 03, and 04.
The first 24 factory-defined groups (01A – 12B) are “pair”
groups that can be used for single (up to 4 beltpacks) and dual
(up to 8 beltpacks) BTR-800 systems. They are arranged
01A, 01B, 02A, 02B…011B, 012A, 012B. A “pair” group,
like 1A and 1B, have different base station transmit frequen-
cies, however, they both have the same eight base station re-
ceive channels from which to choose. Each channel represents
a unique frequency. For example, one BTR-800 could be set
on Group 02A and channels 01, 02, 03 and 04. The other
BTR-800 could be set on Group 02B channels 05, 06, 07 and
08. As long as the channels are different, everything should
be fine.
5. Place the front panel IC A and IC B “IN” and “OUT” level
controls in the 12:00 o’clock position. Check that front
panel IC A and B is in 2-wire for AudioCom (Telex), RTS
-TW and ClearCom wired systems, and 4-wire for RTS
Matrix and stand-alone operation.
6. Place batteries in the beltpacks.
7. Remove the rear switch cover on the beltpacks. Set the
beltpack rear panel slide switch to push-to-talk (PT
TALK).
8. Press [MENU] as powering-up each beltpack. This will
place the beltpack on group 01A with the channel 01
flashing.
The next 12 groups (13 – 24) are single groups that primarily
are used for single (up to 4 beltpacks) BTR-800 systems. The
number of channels from which to choose from in these
groups will vary from group to group.
9. Use the [UP] and [DOWN] arrow buttons to change the
channel to match a channel on the base station. Then press
[SET]. If leaving on channel, just press [MENU]. Each
beltpack should have a unique channel number.
User-Programmable Groups
10. The group/channel on the beltpack should now match the
group and a receive channel on the base station. Nothing
should be flashing on the beltpack screens.
The 12 user-programmable groups are initially empty. The
transmit and receive frequencies are fully editable within these
groups. In fact, factory-defined groups may be copied to
user-programmable groups and then edited if desired. See the
“BTR-800 Menu Structure” and “TR-8XX Menu Structure”
instructions in this section for details on how to copy and edit
frequencies.
11. Plug headsets into the beltpacks and set the microphone
gain so the BAT/OM LED will flash at the beginning of
most words at normal speech levels.
DONE.

If you have followed the instructions in Section 4, “Initial
Equipment Set-Up”, you should now be ready to turn the base
station on.
Intercom Select Button - Press the [SELECT] button to
choose between 2-wire or 4-wire intercom systems. The
green LED will indicate the current mode of the intercom
channel. If the base station is connected to a 2-wire sys-
tem, such as Audiocom (Telex), RTS TW or Clear-Com®,
set the intercom to 2-wire. If it is connected to a
four-wire system, such as RTS Matrix, set the intercom to
4-wire. It is also possible to have intercom A connected
to a 2-wire system and intercom B connected to a 4-wire
system or vice versa. The selection is retained in
non-volatile memory, so it will come-up where last left if
the unit is power cycled.
Set the base station power switch to the on position, by push-
ing the top of the switch.The internal cooling fan will start im-
mediately and the LCD display and front panel indicator lights
will come on in five or six seconds.
Local Headset
Talk Button - Press to enable the audio path from the local
headset. The TALK/O.M. LED will turn green when audio
is enabled. A quick press and release latches on the button.
If the talk function is latched on, pressing the talk button
again will turn it off. If the local headset is not being used,
the talk button should be off. This keeps additional noise
out of the system.
In Level Control - Adjusts the audio level of the wired
intercom system’s input to the base station.
Out Level Control - Adjusts the audio level of the base
station’s output to the wired intercom system.
If the base station is used stand-alone, no wired intercom sys-
tem connected, it must be set in the 4-wire mode. The 2-wire
mode requires a wired intercom system or appropriate load be
connected to the intercom A or B XLRs. If not loaded, a large
gain increase will take place in the unload intercom channel
which may be high enough to produce a loud “howling”
sound.
Microphone Gain - Adjusts the headset’s microphone
gain. Adjust so the TALK/O.M. LED flashes from green
to red on loudest speech.
Headset Intercom Select Button - Select the intercom
system to connect to the local headset. Each press of the
[SELECT] button changes the connection; Channel A,
Channel B and Both. The cycle will then repeat. The
LEDs above the [SELECT] button light to indicate the
current selection.
Auxiliary
Auxiliary Input Select Button - Press the [SELECT]
button to turn on or off the auxiliary input to the base sta-
tion. The selection is retained in non-volatile memory, so
it will come-up where last left if the unit is power cycled.
Volume - Adjust the volume to the headset by rotating the vol-
ume control as required for a comfortable listening volume.
Portable Station Connect
In Level Control - Adjusts the audio level of the wired
auxiliary system’s input to the base station.
Select the audio paths from the base station’s four receivers that
you wish to enable. The corresponding LED above the select
button is on when the audio path is enabled. If a beltpack user
has their portable station connect path off at the base, that user
will no longer hear their sidetone and their audio will not be
passed to anyone. The user will still be able to hear everyone.
The selection is retained in non-volatile memory, so it will
come-up where last left if the unit is power cycled.
Out Level Control - Adjusts the audio level of the base
station’s output to the auxiliary XLR plug.
The auxiliary output connects only to intercom B. It does not
interface to intercom A. The auxiliary input may be switched
to B intercom (default) or A and B intercom. See Section 5 for
the location of this internally located input routing switch. The
auxiliary output is always available at the back panel output
XLR. It cannot be switched on or off like the input. Both the
input and output are balanced audio ports. Auxiliary input and
output audio is global. See Section 5 for more details.
Always disable unused audio receive paths. This reduces the
chances that external RF noise can get onto the audio buses
via an open receiver.

enabled. A quick press and release latches the talk function
unless latching has been disabled. Holding the button for over
½ a second will cause the audio path to be enabled only for as
long as the button is held. If the talk function is latched on,
pressing the talk button again will turn it off. See the “Talk
Button Latching/Non-Latching” instructions in Section 7 to
learn how to enable/disable latching of the talk button.
Wireless Talk Around (WTA)
When pressed, the audio from the beltpack is disconnected
from the wired intercom, auxiliary input/output and the base
station’s local headset. Other beltpack users, on that audio
channel, can hear the user as normal. The button activates the
nearby red LED as well as the appropriate talk LED when
pressed. See the “Wireless Talk Around Enable/Disable” in-
structions in Section 7 to learn how to enable/disable the WTA
button as well as other features.
Microphone Gain
Adjusts the headset’s microphone gain. Adjust so the TALK/OM
LED flashes red at the beginning of most words at normal speech
levels. If the input is too large, the LED will be red during the
complete word at normal speech level. The peak-responding au-
dio limiter in the beltpack is very tolerant of high input audio lev-
els. Even when the microphone gain is maximized, and headset
volume reduced to make up for the louder audio, the audio will
still sound good and not clipped.

System Walk-Thru
Now that you have successfully “set-up” your Telex Wireless
Intercom System and turned on any auxiliary equipment, you
are ready to test the overall performance by “Walking” the
Telex system through the areas in which you will be using it.
The “system walk-thru” can detect problem of weak signal
strength caused by:
Poor antenna location
•
Before you begin your walk-thru, check the following:
Wrong antenna for receiver and/ or transmitter
•
Beltpack Battery Check.
r
RF “Trouble Spots”
•
Set microphone gain in both the beltpack(s) and the
base station.
Operating distance beyond system capability.
r
•
Old or used batteries in the TR-8XX.
The base station and beltpack(s) are on the same group
r
•
and the beltpack(s) are on their own unique transport
channels that match the base station receive channels
Under normal conditions the base station’s display will indicate
a beltpack status. “Weak Signal” condition will result in “no tx”
being displayed on the base station’s receiver for that beltpack.
Check that the talk button is engaged. The talk LED
will be illuminated.
r
In 99% of all instances you will set up your Telex Wireless In-
tercom System, walk it through the area of interest and
achieve error-free performance. If in the rare instance your
Telex system does not “pass” during your walk-thru evalua-
tion, refer to the section of this manual which deals with Sys-
tem Troubleshooting.
Intercom Level “IN” and “OUT” are set to an appro-
priate level.
r
Auxiliary Level “IN” and “OUT” are set to an appro-
priate level (if used).

Troubleshooting
Reread the sections of this manual to make sure you have
completed system set-up properly.
If you are unable to solve the problem, contact the dealer from
whom you purchased the system for assistance.
PROBLEM
SOLUTION
DISTORTION - System’s audio quality seems distorted
at medium to high input levels.
Reduce microphone gain by adjusting microphone gain
control.
Check the gain setting on all beltpacks and the base. They
may be too low or too high. Check to make sure you are
still well within range of the base station.
HISS - System seems to produce a “hiss” which is
undesirable.
Check the gain setting on both the beltpacks and the base.
They may be too low.
LOW OUTPUT - System produces a low output level.
FEEDBACK - Moving around area of use produces
“squeal” or “howl” in various locations using ext.
speakers.
Reduce the gain settings on both the beltpacks and the
base. They may be too high.
Make sure both antennas on the base and beltpack are
connected and follow the location suggestions. Change the
location of the base unit and antennas or avoid the bad
areas with the remote beltpacks.
DROPOUTS - When moving around the area of use there
seems to be locations where the signal “swooshes” or
completely disappears.
Make sure that all the Telex beltpack(s) are on. If there are
any unused receivers at the base, turn the audio off from
those receivers by deselecting the appropriate “Portable
Station Connect” button.
INTERFERENCE - System picks up signals other than
wireless intercoms.
If problems persist with the beltpack on, you will probably
need to change the group. Make sure the base and
beltpack match after any Group/Channel change.
Check Transmitter switch on base and beltpack. Check
talk LED to make sure it is on. Make sure beltpack
batteries are OK.
NO AUDIO from BASE or BELTPACK headsets.

Tech Tips
Frequency Interaction
Unfortunately, radio frequency (RF) channels cannot be ran-
domly selected for use in radio devices. They must be selected
to avoid known frequencies in use, FCC restrictions on the lo-
cation of devices, and even interference between your own RF
devices. The factory defined frequencies (Groups 01A-24) se-
lected by Telex for this RadioCom™ system are chosen to
minimize possible interference.
Figure 34 displays the same gain setting as in Figure 33 but
brought into a high noise environment. The user’s voice now
lights the OM indicator all the time he or she speaks due to the
higher noise plus the user speaking louder. The result on the
system is distortion on louder speech. The microphone gain
must be reduced. The same applies to a user with a powerful
voice. If someone sets the system mic gain to their voice and
user has a much stronger voice, then the gain will need to be
reduced, even if the background noise is the same.
Microphone Gain Adjustment
The microphone gain controls on the base station and beltpack
are set to mid-levels by the factory. In most cases this setting
will work fine and only on loud speech will the
overmodulation (OM) indicator light. However, in environ-
ments where the background noise is loud or the user has a
strong/quiet voice, the gain control will need to be adjusted. In
Figure33 the gain is set correctly. The user’s root-mean-square
(RMS) sound level is well below the OM threshold and only
on peaks does his or her voice flash the OM indicator light.
Always remember to set the microphone gain based on the sit-
uation and location in which the equipment will be used. If the
equipment is used on the field during a football game, set the
gain based upon a loud stadium, NOT the quiet stadium 2
hours before a game. If a production studio user has a quiet
voice, set the gain to their voice and NOT the stage hand’s
loud voice who helped set up the system.

Battery Information
Improper battery selection, use, installation and care are the
cause of numerous wireless system failures.
Battery Life:
TR-800
Alkaline, 12-14 Hours
Nickel Metal Hydride, 9-11 Hours
Alkaline Batteries: Alkaline batteries such as Mallory’s
DURACELL® or Eveready’s ENERGIZER® provide the
most reliable operation in wireless transceivers.
TR-825
Alkaline, 9-11 Hours
Nickel Metal Hydride, 7-9 Hours
The use of low cost carbon-zinc batteries is NOT recom-
mended.
Nickel-Metal Hydride Batteries: These batteries can save
you money in the long run, as they can be recharged. Typical
battery life is about 70-80% of the length of time alkaline bat-
teries last.
