FEATURES
Your RadioShack Translucent Cordless
Headset Telephone gives you communi-
cation with both portability and conve-
nience. It comes in two parts, a headset
and a base.
The phone’s headset connects to a cord-
less remote keypad, so you can make
calls away from its base. The headset lets
you keep your hands free to do other
things such as cook or work at your com-
puter while you talk. The base’s space-
saving, upright design makes it perfect for
areas where space is limited.
Your phone includes these features:
Advanced Super CCT Circuitry — pro-
vides sound clarity comparable to that of
a corded phone.
Security Access-Protection Code —
prevents other cordless phone users from
using your phone line while the remote
keypad is off the cradle.
COM-LOK®— ensures that other cord-
less phone users cannot use your phone
line when the remote keypad is on the
cradle.
10-Number Memory Dialing — lets you
store 10 numbers in memory for easy di-
aling.
Auto Scan — automatically selects a
clear channel when you pick up the
phone. You can also manually switch to
another channel.
Redial — lets you redial the last number
dialed, with the touch of a button.
Privacy — prevents the person on the
other end of the phone line from hearing
you as you talk to someone else in the
room.
Flash — sends an electronic switchhook
signal for use with special phone services
such as Call Waiting.
Touch-Tone or Pulse (Rotary) Dialing
— lets you use your phone with either
type of service.
Belt Clip — lets you carry the phone’s re-
mote keypad on your belt for easy porta-
bility.
Hearing-Aid Compatibility — lets you
use your phone with hearing aids that
have a T (telephone) switch.

This phone has been tested and found to
comply with all applicable UL and FCC
standards.
Important Note: Cordless phones such
as this one require AC power to operate.
When the AC power is off, you cannot dial
out or receive incoming calls using your
telephone. To be safe, you should also
have a phone that does not need AC
power to operate (not a cordless phone)
so you can still make and receive calls if
there is an AC power failure.
Note: Your phone operates on standard
radio frequencies as allocated by the
FCC. It is possible for other radio units
operating nearby on similar frequencies
to unintentionally intercept your conversa-
tion or cause interference. This possible
lack of privacy can occur with any cord-
less phone.
This symbol is intended to alert you to
the presence of uninsulated dangerous
voltage within the product’s enclosure
that might be of sufficient magnitude to
constitute a risk of electric shock. Do not
open the product’s case.
This symbol is intended to inform you

READ THIS BEFORE
INSTALLATION
We have designed your phone to conform
to federal regulations, and you can con-
nect it to most telephone lines. However,
each device that you connect to the
phone line draws power from the phone
line. We refer to this power draw as the
device’s
ringer equivalence number , or
REN. The REN is on the bottom of the
base.
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 (three
in rural areas), your phones might not
ring. If ringer operation is impaired, re-
move a device from the line.
FCC STATEMENT
This telephone complies with Part 68 of
FCC Rules . You must, upon request, pro-
vide the FCC Registration Number and
the REN to your phone company. These
numbers are shown on the bottom of the
base.
Note: You must not connect your phone
to any of the following:
• coin-operated systems
• party-line systems
• most electronic key phone systems

INSTALLATION
SELECTING A LOCATION
You can place the phone’s base on a
desktop, shelf, or table. Select a location
that is:
• near an AC outlet
• near a telephone line jack
• out of the way of normal activities
• away from electrical machinery, elec-
trical appliances, metal walls, filing
cabinets, wireless intercoms, security
alarms, and room monitors
The base’s location affects the phone’s
range. If you have a choice of several lo-
cations, try each to see which provides
the best performance.
Your telephone connects directly to a
modular telephone line jack. If your tele-
phone wiring does not have a modular
jack, you can update the wiring yourself
or have the telephone company update it
for you.
Notes:
• RadioShack stores sell jacks and
adapters to convert older wiring meth-
ods to modular wiring.
• The USOC number of the jack to be
installed is RJ11C.
Caution: The supplied adapter is a Class
2 120V AC/12V DC adapter that delivers
at least 200 milliamps with its center tip
set to positive. Its plug correctly fits the
phone’s DC 12V jack. Using an adapter
that does not meet these requirements
could damage the phone or the adapter.
CONNECTING THE PHONE
After you select a location for the phone’s
base, follow these steps to connect it to
AC power and to the phone line.
1. Plug one end of the supplied modular
cord into the TEL. LINE jack on the
back of the base.
2. Plug the modular cord’s other end
into a modular phone line jack.

3. Plug the supplied AC adapter’s barrel
plug into the DC 12V jack on the back
of the base.
4. Plug the adapter into a standard AC
outlet. The IN USE/CHARGE indica-
tor lights when the keypad is in the
base.
5. Lift the base’s antenna to a vertical
position.
CONNECTING AND
CHARGING THE BATTERY
PACK
The telephone comes with a recharge-
able nickel-cadmium battery pack in the
remote keypad. You must connect and
then charge the battery pack for at least
15 hours before you use it the first time.
1. Use a Phillips screwdriver to remove
the screw that secures the battery
compartment cover, then remove the
cover.
2. Slide the battery pack’s connector
onto the connector pins inside the
battery compartment.
3. Replace the cover and secure it with
the screw.
4. To charge the battery pack, place the
remote keypad in the base. The IN
USE/CHARGE indicator on the base
lights.

Recharge the battery pack when the
TALK/LOW BATT indicator lights.
Notes:
• When you first use the phone after
charging or recharging the battery
pack, the phone might not work and
you might hear error tones. (You do
not hear the error tones if POWER is
set to OFF.)
If you hear the error tones, return the
remote keypad to the cradle for at
least 5 seconds to reset the security
access-protection code.
• About once a month, fully discharge
the battery pack by keeping the
phone off the base until the TALK/
LOW BATT indicator lights. Other-
wise, the battery pack loses its ability
to fully recharge.
• If battery power is low, POWER is set
to ON, and the headset is not in use,
the TALK/LOW BATT indicator slowly
flashes. If battery power is too low,
the indicator does not light.
• If the IN USE/CHARGE indicator
does not light when you place the re-
mote keypad on the base, be sure the
battery pack and AC adapter are cor-
rectly and securely connected. Also,
check the charging contacts on the
remote keypad and base. If the con-
tacts are dirty or tarnished, clean
them with a pencil eraser.
• If you are not going to use your phone
for an extended period of time, dis-
connect its battery. This helps to in-
crease the battery’s usable life.

ATTACHINGTHEHEADSET
HOLDER
Put the headset holder into the slot on the
back of the base and slide it into place.
ADJUSTING THE HEADSET
1. Put on the headset, and adjust the
band until it rests with almost no pres-
sure on your ear and the top of your
head.
If the headset is loose, remove it and
gently push the headset band inward
slightly to tighten it. If the headset is
tight, gently pull the headset band out
to loosen it.
2. Hold the headset in place, and turn
the microphone boom until it is about
2 inches from your mouth.
When you are not using the headset,
place it on the headset holder.

SETTING THE DIALING
MODE
Set TONE-PULSE on the side of the base
for the type of service you have. If you are
not sure which type you have, do this sim-
ple test after charging the battery.
1. Set POWER to ON.
2. Set TONE-PULSE to TONE.
3. Lift the remote keypad from the base.
Then press TALK/HANG UP and listen
for a dial tone.
4. Press any number other than 0.
If the dial tone stops, you have touch-
tone service. Leave TONE-PULSE set
to TONE.
If the dial tone continues, you have
pulse service. Set TONE-PULSE to
PULSE.
USING THE BELT CLIP
Use the belt clip to hang the remote key-
pad on your belt or waistband for hands-
free carrying.
