Even when the transceiver power is OFF, a slight current still
flows in the circuits. Remove the battery pack or case from
the transceiver when not using it for a long time. Otherwise,
the battery pack or installed dry cell batteries will become ex-
hausted.

DAntenna
DBelt clip
Conveniently attaches to your belt.
CAUTION: Transmitting without an
antenna may damage the transceiver.
To attach:
Slide the belt clip into the plastic loop on the back of the bat-
tery case/pack.
Insert the supplied antenna into the an-
tenna connector and screw down the an-
tenna as shown at right.
Keep the jack cover attached when jacks
are not in use to avoid bad contacts from
dust and moisture.
To remove:
Push the top of the belt clip towards the transceiver and at
the same time, push it downward and free of the plastic loop.
DBattery pack replacement
To remove:
Push and hold the bat-
tery release downwards,
then pull the battery
pack upwards as shown
at right.

■ Repeater operation
A repeater amplifies received signals and retransmits them
on a different channel, allowing you to communicate over
greater distances with improved reliability. When using a re-
peater, the transmit channel is shifted from the receive chan-
nel by 30 channels.
DSetting CTCSS tones for
[
repeater and tone squelch
operation
Repeaters may require CTCSS (subaudible) tones to be ac-
cessed. CTCSS tones are superimposed over your normal
signal and must be set in advance.

channel).
This setting is commonly used for the tone squelch operation.

■ Scan types
■ Open scan
The transceiver has 3 scan types with tag functions and 4 re-
sume conditions providing scanning versatility.
Open scan searches for transmitted signals automatically and
makes it easier to locate new stations for contact or listening
purposes.
Tag channels are independently set for open, group and pri-
ority scans. Initially, all channels may be set as tag channels
for all scans.
During open scan, transmission is not possible except on a
busy channel.

■ Tone squelch operation
■ Pocket beep operation
The tone squelch opens only when receiving a signal con-
taining a matching CTCSS (subaudible) tone.You can silently
wait for calls from group members using the same tone.
This function uses CTCSS (subaudible) tones for calling and
can be used as a “common pager” to inform you that some-
one has called while you were away from the transceiver.
q Set the desired channel.
w Set the desired CTCSS tone in set mode.

q Set the operating channel.
•See p. 7 for tone frequencies and programming information.
e Push [–] for 2 sec. several times until “TSQL” appears.
r When the received signal includes a matching tone,
squelch opens and the signal can be heard.
w Set the desired CTCSS tone in set mode.
•See p. 7 for tone frequencies and programming information.
e Push [–] for 2 sec. several times until “ TSQLë” appears
in the function display.
•When the received signal’s tone does not match, tone squelch
does not open, however, the S-indicator shows signal strength.
•To open the squelch manually, push [–].
r When a signal with the correct tone is received, the
transceiver emits beep tones and flashes “ TSQLë.”
t Push [PTT] to answer or push [–] to stop the beeps and
flashing.
t Operate the transceiver in the normal way.
y To cancel the tone squelch, push [–] for 2 sec. twice.
•Tone squelch is automatically selected.
NOTE:The transceiver has 51 tone frequencies and con-
sequently their spacing is narrow compared with units hav-
ing 38 tones. Therefore, some tone frequencies may
receive interference from adjacent tone frequencies.
DCalling a waiting station using pocket beep
A subaudible tone matched with the station’s tone frequency
is necessary. Use the tone squelch at left or a CTCSS (sub-
audible) tone encoder (p. 7).
Tone frequencies and tone squelch ON/OFF settings are
automatically stored in memory channels for easy recall.

charging of battery packs.
One AD-81 and an AC adapter (may be
supplied with the BC-119 depending on

NEVER attempt to charge dry cell bat-
teries. This will cause internal liquid
leakage and damage the battery case
and transceiver.
The BP-195 or BP-196 BATTERY PACK in-
cludes rechargeable Ni-Cd batteries

Check orientation
If you want to be able to charge the bat-
tery pack more than 300 times, the fol-
lowing points should be observed:
1.Avoid overcharging. The charging pe-
riod should be less than 48 hours.
2.Use the battery until it becomes al-
most completely exhausted under
normal conditions. We recommend
battery charging just after transmitting
becomes impossible.

■ About the battery pack
■ Installing batteries in the
battery case
When using a battery case, install 8 AA (R6) size Ni-Cd or al-
kaline batteries as illustrated below.
DOperating period
Depending on the attached battery pack, the operating period
of the transceiver varies. Refer to the last page for battery
pack specifications.
q Remove the bat-
tery case from the
transceiver.
DBattery pack life
If your battery pack seems to have no capacity even after
being fully charged, completely discharge it by leaving the
power ON overnight. Then, fully charge the battery pack
again.
w Install 8 × AA (R6)
size Ni-Cd or alka-
line batteries.
If the battery pack still does not retain a charge (or very little),
a new battery pack must be purchased.
•Be sure to observe
the correct polarity.
■ NEVER connect DC power to the transceiver when in-
stalling dry cell or alkaline batteries. Such a connection will
damage the transceiver.
■ Be careful of battery overcharging. When operating via ex-
ternal DC power, installed batteries are simultaneously
charged.
■ Keep battery contacts clean. It’s a good idea to clean bat-
tery terminals once a week.
