For your records, we recommend
you record the phone’s serial number
in the space below. The number is on
the base’s label.
READ THIS BEFORE
INSTALLATION
Your telephone conforms to federal
regulations, and you can connect it to
most telephone lines. However, each
device you connect to the phone line
draws power from the phone line. We
refer to this power draw as the de-
vice’s ringer equivalence number, or
REN. The REN is on the label on the
phone base’s back.
Serial Number:
Warning: To prevent fire or shock
hazard, do not expose this product to
rain or moisture.
CAUTION
RISK OF ELECTRIC SHOCK.
!
DO NOT OPEN.
If you are using more than one phone
or other device on the line, add up all
the RENs. If the total is more than
five, your phone might not ring. In ru-
ral areas, a total REN of three might
impair ringer operation. If ringer op-
eration is impaired, remove a device
from the line
CAUTION: TO REDUCE THE RISK OF
ELECTRIC SHOCK, DO NOT REMOVE
COVER OR BACK. NO USER-SERVICE-
ABLE PARTS INSIDE. REFER SERVIC-
ING TO QUALIFIED PERSONNEL.
This symbol is intended to alert
you to the presence of uninsulat-
ed dangerous voltage within the
product’s enclosure that might be
of sufficient magnitude to consti-
tute a risk of electric shock. Do not
open the product’s case.
Important: Cordless phones such as
this one require AC power to operate.
When AC power is off, you cannot
dial out or receive incoming calls us-
ing your ET-905. For this reason, the
ET-905 should not be your only tele-
phone. To be safe, you should also
have a phone that draws its power
from the telephone line (not a cord-
less phone) so you can still make and
receive calls if there is an AC power
failure.
This symbol is intended to inform
you that important operating and
maintenance instructions are in-
cluded in the literature accompa-
nying this product.

FCC STATEMENT
This telephone complies with part 68
of FCC Rules. You must, upon re-
quest, provide the FCC Registration
Number and the REN to your phone
company. These numbers are on the
label on the phone base’s back.
You must not connect your phone to
any of the following:
• Coin-operated systems
• Party-line systems
• Most electronic key phone sys-
tems
Note: Your telephone operates on
standard radio frequencies, as allo-
cated by the FCC. Even though the
access protection code prevents un-
authorized use of your phone line, it
is possible for other radio units oper-
ating on similar frequencies within a
certain area to unintentionally inter-
cept your conversations and/or
cause interference. This lack of pri-
vacy can occur with any cordless
phone.

return the handset to the base
and fully recharge the battery.
• Some deeply discharged batter-
ies take longer to charge. If
overnight charging is not suffi-
cient, try charging for up to 48
hours.

TROUBLESHOOTING
We do not expect you to have any
problems with your phone, but if you
do, first check another phone on the
same line to determine if the problem
is with the phone service. If it is not,
try the following suggestions.
Telephone is Dead, or No
Dial Tone
Several situations can cause this. If
you have this difficulty:
• Be sure the handset’s battery is
fully charged and the handset is
in the talk mode.
If you cannot determine the cause of
the problem, take the phone to your
local Radio Shack store for assis-
tance.
• Be sure the phone line cord is
securely connected to the jack.
• Be sure the cord is not dam-
aged.
False Ringing
• Be sure the jack is properly
wired.
Cordless phones can receive false
ringing signals caused by other radio
devices. To help prevent false ring-
ing, your phone has a digital security
system with over one million code
combinations. In the unlikely event
that false ringing does occur, move
the base or the interfering transmitter
to another location.
• Be sure the handset’s battery
pack is securely connected.
Can Receive But Not Make
Calls
• Be sure you are in the talk mode
• Check if PULSE/TONE is set cor-
rectly
Noise Interference in Your
Conversation
If you experience interference, move
the handset closer to the base and
move the base away from sources of
interference (such as power lines,
large motors, etc.). Try not to plug the
base into a circuit that also provides
power to a major appliance.
Phone Still Does Not Work
Reset your phone as follows:
1. Disconnect the adapter from the
AC outlet, then connect it again.
2. Disconnect the battery pack’s
wire from the handset, then con-
nect it again (see “Replacing the
Handset Battery”).

A short repeating beep
No Channel Available
Simply press TALK again.
If the phone is unable to
find a channel after sever-
al tries, it does not mean
your telephone is not

there are too many calls in
this band at the time. Sim-
ply use a corded tele-
phone to make your call or
wait a few minutes before
trying again.

MAINTENANCE
Your Radio Shack ET-905 900 MHz Cordless Telephone is an example of su-
perior design and craftsmanship. The following suggestion will help you care for
your phone so you can enjoy it for years.
Keep the phone dry. If it gets wet, wipe it dry immediately. Liquids
contain minerals that can corrode electronic circuits.
Handle the phone gently and carefully. Dropping it can damage
its circuit boards and cases and cause it to work improperly.
Use and store the phone only in normal temperature environ-
ments. Temperature extremes can shorten the life of electronic
devices, damage batteries, and distort or melt plastic parts
Keep the phone away from dust and dirt, which can cause pre-
mature wear of parts.
Wipe the phone with a damp cloth occasionally to keep it looking
CLEANER
new. Do not use harsh chemicals, cleaning solvents, or strong
detergents to clean the phone.
Modifying or tampering with the phone’s internal components can cause a mal-
function and might invalidate its warranty and void your FCC authorization to op-
erate it. If your phone is not performing as it should, take it to your local Radio
Shack store for assistance. If the trouble is affecting the phone lines, the phone
company might ask you to disconnect your phone until you have resolved the
problem.

3. Turn the steel strap clockwise
and pull back to release it.
REPLACING THE
HANDSET BATTERY
When the handset’s battery no long-
er recharges, replace the battery.
Use only a 3.6V, 650 mA battery with
a connector that fits the connector in
the battery compartment. You can
order a replacement battery from
your local Radio Shack store.
4. Remove the battery pack and
pry out the battery wires’ plug
using a small flat-blade screw-
driver.
1. Press down on top of the hand-
set’s battery compartment cover
(on the three raised bars on the
lower back) and slide it off.
5. Insert the new battery pack’s
plug into the receptacle and
firmly push down to make sure it
is properly connected.
2. Using a Phillips screwdriver, turn
the stainless steel strap’s screw
counterclockwise to loosen it
slightly.

pack and the back cover.
THE FCC WANTS YOU
TO KNOW
In the unlikely event that your phone
causes problems on the phone line,
the phone company can temporarily
discontinue your service. The phone
company normally attempts to notify
you in advance. If advance notice is
not practical, the phone company no-
tifies you as soon as possible and ad-
vises you of your right to file a
complaint with the FCC.
7. Replace the screw in the strap
and tighten it, then replace the
battery cover.
Notes:
Also, the phone company can make
changes to its lines, equipment, op-
erations, or procedures that could af-
fect the operation of this telephone.
• You must charge a new battery
at least 24 hours before you use
it the first time.
• The phone uses one recharge-
able nickel-cadmium battery
pack. At the end of the battery’s
useful life, it must be recycled or
disposed of properly. Contact
your local, county, or state haz-
The phone company normally noti-
fies you of these changes in ad-
vance, so you can take the
necessary steps to prevent interrup-
tion of your phone service.

Your phone might cause TV or radio
interference even when it is operat-
ing properly. To determine whether
your phone is causing the interfer-
ence, turn off and unplug your phone
and disconnect the handset battery.
If the interference goes away, your
phone is causing the interference.
LIGHTNING
Your phone has built-in protection
circuits to reduce the risk of damage
from surges in phone line current.
These protection circuits meet or ex-
ceed FCC requirements. However,
lightning striking the phone lines can
damage your phone.
Try to eliminate the interference by:
Lightning damage is not common.
Nevertheless, if you live in an area
which has severe electrical storms,
we suggest that you unplug your
phone during storms to reduce the
possibility of damage.
• Moving your phone away from
the receiver
• Connecting your phone to an AC
outlet that is on a different elec-
trical circuit from the receiver
• Contacting your local Radio
Shack store for help
If you cannot eliminate the interfer-
ence, the FCC requires that you stop
using your phone.
