FEATURES
Your RadioShack Telephone Listener amplifies your calls through its built-in
speaker so everyone in the room can hear. The Listener’s features include:
•Suction Cup Pickup Coil — makes attachment to the telephone easy and
convenient. The coil is designed so you can attach it (depending on the
type of phone you use) to just about anywhere on the phone.
•Volume Control — lets you adjust the Listener’s volume to a comfortable
listening level.
•Two Power Sources — let you power your Listener from an internal bat-
tery or standard AC power (with an optional AC adapter).
•Mounting Options — you can place the Listener on a desktop or table, or
mount it directly on the wall.

PREPARATION
CONNECTING TO POWER
You can power your Listener from either an internal battery or AC power.
Using Battery Power
To power the Listener from an internal battery, you need one 9-volt battery (not
supplied). For the best performance and longest life, we recommend an alkaline
battery, such as RadioShack Cat. No. 23-553.
Caution: Always use a fresh battery of the required size and recommended
type.

1. Insert a coin into the slot between the front and back halves of the case,
and twist it slightly to separate the halves, then lift off the front case.
2. Snap the battery connector over the battery’s terminals.
3. Place the battery on top of the foam cushion inside the front case, then
place the back case over the front case and snap it closed.
When the Listener’s volume drops or the sound
distorts, replace the 9-volt battery.

Cautions:
• If you do not plan to use the Listener for a week or more, or if you plan to
use only an AC adapter, remove the battery. Batteries can leak chemicals
that can destroy electronic parts.
• Dispose of old batteries promptly and properly. Do not burn or bury them.
Using AC Power
To power the Listener from a standard AC outlet, you need an AC adapter such
as Cat. No. 273-1431.

Cautions:
• You must use an AC adapter that supplies at least 7.5 volts DC power and
delivers at least 300 milliamps. Its center tip must be set to positive, and its
barrel plug must properly fit the Listener’s 9V DC jack. The recommended
adapter meets these requirements. Using an adapter that does not meet
these requirements could damage the Listener or the adapter.
• To prevent damage to the Listener or the adapter, be sure you connect the
adapter to the Listener before you plug it into the AC outlet, and unplug the
adapter from the AC outlet before you unplug it from the Listener.
Insert the adapter’s barrel plug into the Listen-
er’s 9V DC jack, then plug the adapter into a
standard AC outlet.

Note: Connecting the AC adapter automatically disconnects the internal bat-
tery.
MOUNTING
You can place the Listener on a flat surface, such as a shelf or desk top, or
mount it directly on the wall.
To mount the Listener on the wall, you need two flat-head screws (not supplied)
with heads that fit into the keyhole slots on the back of the Listener.
Drill two holes 215/16 inches (75 mm) apart.
Then thread a screw into each hole, letting
the heads extend about 1/4inch (6 mm) from
the wall.

screws and slide the Listener downward to se-

2. Rotate the volume control to about its
middle position (3).
3. Set ON/OFF to ON.
Note: To prevent feedback, do not place
the suction cup pickup coil near the Lis-
tener’s speaker.
4. Because telephone designs vary greatly,
you might need to try attaching the
pickup coil at different locations on your
telephone. Start by pressing the suction
cup against the back of the handset,
opposite the receiver’s earpiece. Then
lift the telephone handset off the cradle.

5. While listening to the dial tone through the Listener’s speaker, move the
suction cup to different locations on the phone. Try the left rear corner of
the phone’s base, as well as around the receiver’s earpiece. Keep moving
the suction cup pickup coil until you find the position that provides the best
sound quality and volume.
6. When you finish, leave the suction cup attached to the telephone and set
ON/OFF to OFF.
