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.

barrel plug into the DC 9V jack  
on the bottom of the base and  
route the wire through the slot  
on the back of the base.  
You can place the base on a desk,  
shelf, or table, or mount it directly on  
the wall. The base’s location affects  
the phone’s range. If you have a  
choice of several locations, try each  
to see which one provides the best  
performance.

will lose its ability to recharge,  
and you might have to recharge  
and replace it more often.  
Note: If the CHARGE indicator does  
not light or blinks continuously when  
you place the handset on the cradle,  
be sure the battery and AC adapter  
are correctly and securely connect-  
ed. Also, check the charging con-  
tacts on both the handset and base.  
If the contacts are dirty or tarnished,  
clean them with an eraser.  
To fully discharge the battery,  
keep the handset off the cradle  
until BATT LOW lights. Then  
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  
working, but simply that  
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.  
6. Insert the steel strap’s hooked  
end into the slot beside the bat-  
tery connector and hold it up  
while you place the new battery  
pack in the compartment.

43-1080.fm Page 18 Tuesday, August 17, 1999 1:51 PM  
Note: Make sure the excess  
wires are between the battery  
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.  
ardous  
waste management  
authorities for information on  
recycling or disposal programs  
in your area. Some options that  
might be available are: munici-  
pal curbside collection, drop-off

43-1080.fm Page 19 Tuesday, August 17, 1999 1:51 PM  
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.
