Advanced 3-Station FM Wireless Intercom System
Your RadioShack Advanced 3-Station FM
Wireless Intercom System is convenient and
easy to use. Installation is quick and simple.
Simply plug each of the three supplied sta-
tions into a standard three-wire AC outlet,
and you are ready to send and receive calls
or monitor an area where a station is in-
stalled. Each of your intercom’s stations has
the following features:
Adjustable Volume Control — allows you
to alter the volume to suit the noise level in
the room.
Lockable Talk Bar — allows you to talk to or
monitor a room hands-free.
Call Tone — alerts other stations before you
start talking.
Desk or Wall Mounting Capabilities —pro-
vide easy, convenient placement of stations.
Your intercom system is ETL listed and
meets all applicable FCC standards.
INSTALLATION
You can install the stations almost anywhere
there is a standard AC outlet. Simply plug
each station into an outlet and place it direct-
ly on a desk, shelf, table or on a wall.
Important: Stations can transmit up to 300
feet and between buildings as long as they
are connected to the same power line trans-
former.
Note: Make sure you install the stations at
least 10 feet away from each other. Placing
the stations too close together produces
feedback and creates a squealing sound.
Mounting
To mount a station on the wall, you need two
screws (not supplied) with heads that fit into
the keyhole slots on the bottom of the sta-
tions.
1. Select a location for the station. Mark
the mounting screw locations on the wall
29/16 inches (64.8 mm) apart, one above
the other.
WARNING: To reduce the risk of fire or
shock hazard, do not expose this product to rain

2. Drill holes at the marked locations.
3. Thread a screw into each hole allowing
the screw heads to extend about 1/8inch
(3 mm) from the wall.
4. Align the keyhole slots on the bottom of
the station with the screw heads in the
wall. Slide the station down onto the
screws to secure it.
OPERATION
Setting the Channel
Each station has three channels, so you can
select which station or stations you want to
communicate with. You can also use a station
to monitor sounds near another station.
For example, you could set a station installed
in the kitchen to Channel A, a station installed
in the family room to Channel B, and a station
installed in a bedroom to Channel C. Using
the station installed in the kitchen, you can
communicate with the station in the family
room by setting the channel selector to B, or
with the station in the bedroom by setting the
channel selector to C. Or, if you set all sta-
tions to Channel A, you can communicate with
the other two stations from any station.
Set the channel selector on each station as
follows:
• If you want all the stations to communi-
cate with each other at the same time, set
all stations to the same channel.
• If you want to use a station to communi-
cate with only one of the other stations,
set only those stations to the same chan-
nel.
Turning a Station On and Off/
Adjusting the Volume
Rotate VOLUME counterclockwise until it
clicks. Then adjust VOLUME to a comfortable
listening level. To turn off the station, rotate
VOLUME clockwise until it clicks.
Calling Another Station
1. Be sure the stations you plan to use are
turned on and adjusted to the desired vol-
ume.
2. Set the channel selector to the channel
(A, B or C) for the station(s) you are call-
ing.
3. Press CALL. Each station that is on and
set to the selected channel sounds a
tone.
4. Hold down TALK and speak in a normal
voice. When you finish speaking, release
TALK and listen for the response.
Notes:
• Only one party can talk on a channel at
a time.
• The TALK indicator on the station you
are using remains lit as long as you
hold down TALK or CALL, or when you
press LOCK.
• If your voice sounds distorted, you
might be speaking too loudly or too
close to the microphone.
• Set the channel selector back to your
designated channel after you finish
talking, so others can easily reach you.
Monitoring
You can set any station so it continuously
transmits sounds from the area where it is lo-
cated to another station. For example, you
could set the station in a baby’s bedroom,
then use the station in the kitchen to monitor
the sounds.
Note: You can monitor only one station at a
time.

3
1. Press LOCK on the station in the area you
want to monitor. The TALK indicator
lights.
Note:
The TALK indicator stays lit until
you press CALL or TALK. This lets you
know that the station is transmitting.
2. Set the channel selectors on both sta-
tions to the same channel.
3. When you finish monitoring, release the
lock by pressing TALK or CALL on the
station in the area you are monitoring.
The TALK indicator turns off.
Note: After pressing LOCK on a station,
you cannot call or talk to that station until
you press TALK or CALL to release the
lock.
Using Additional Stations
You can add additional stations to your inter-
com system as long as they transmit on the
same frequency. The stations and their box
are labeled to indicate each station’s frequen-
cy – A (200 kHz), B (270 kHz), or C (230 kHz).
Stations in the same box have the same fre-
quency.
Be sure the letter on the stations you plan to
add matches the letter on your current sta-
tions. If you want to set up a separate inter-
com system, however, be sure it operates on
a different frequency.
THE FCC WANTS YOU
TO KNOW
Your intercom system might cause TV or ra-
dio interference even when it is operating
properly. To determine whether your stations
are causing the interference, turn them off. If
the interference goes away, your stations are
causing it. Try to eliminate the interference by:
• Moving both stations away from the
receiver
• Connecting the stations to outlets that are
on a different electrical circuit from the
receiver
This equipment has been tested and found to
comply with the limits for a Class B digital de-
vice, pursuant to Part 15 of the
FCC Rules
.
These limits are designed to provide reason-
able protection against harmful interference in
a residential installation. This equipment gen-
erates, uses and can radiate radio frequency
energy and, if not installed and used in accor-
dance with the instructions, may cause harm-
ful interference to radio communications.
However, there is no guarantee that interfer-
ence will not occur in a particular installation.
If this equipment does cause harmful interfer-
ence to radio or television reception, which
can be determined by turning the equipment
off and on, the user is encouraged to try to
correct the interference by one or more of the
following measures:
• Reorient or relocate the receiving
antenna.
• Increase the separation between the
equipment and receiver.
• Connect the equipment into an outlet on
a circuit different from that to which the
receiver is connected.
• Consult your local RadioShack store or
an experienced radio/TV technician for
help.
• If you cannot eliminate the interference,
the FCC requires that you stop using your
intercom system.
Changes or modifications not expressly ap-
proved by RadioShack may cause interfer-
ence and void the user’s authority to operate
the equipment.
You must use shielded interface cables with
this equipment.
