INSTALLATION  
You can install the stations almost anywhere there is a  
standard AC outlet. Simply plug each station into an AC  
outlet, then place it on a desk, shelf, or table, or mount it  
on a wall.  
Important:  
• You must connect all of the stations to AC outlets  
originating from the same phase of a power line  
transformer. All AC outlets in most residential and  
many commercial properties are connected to the  
same phase of a power line transformer.  
• Stations can transmit up to 300 feet and between  
buildings as long as they are connected to the same  
phase of a power line transformer.  
To use the stations in a home or office with more than  
one phase of a power line transformer, you need a  
whole house converter, such as RadioShack Cat. No.  
61-2401.  
• Make sure you install the stations at least 10 feet  
apart. Placing the stations too close together pro-  
duces feedback which creates a squealing sound.  
To prevent electric shock, one blade on the  
Caution:  
power cord’s plug is wider than the other so the plug fits  
into the outlet only one way. If you cannot easily insert  
the plug, turn it over and try again. Do not force it.

MOUNTING THE STATIONS  
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 stations.  
Follow these steps to mount a station on the wall.  
1. Mark the mounting screw locations 23/4 inches (70  
mm) apart, one above the other.  
2. Drill a hole at each marked location.  
3. Thread a screw into each hole until the screw’s head  
extends about 1/8 inch from the wall.  
4. Align the keyhole slots on the bottom of the station  
with the screw heads, then slide the station down to  
secure it.

party finishes before answering.  
• 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 (see “Monitoring” on Page  
8).  
• If your voice sounds distorted, you might be speaking  
too loudly or too close to the station.

MONITORING  
You can set one station so it continuously transmits. For  
example, you could set the station in a baby’s bedroom to  
pick up any sounds in that bedroom, then listen at the  
station in the kitchen to monitor the sounds.  
You can monitor only one station at a time.  
LOCK  
1. Press  
on the station in the area you want to  
monitor. Both the TALK and LOCK indicators light.

When you press LOCK on a station, another station  
cannot call or talk to that station until you press TALK  
to release the lock. (Pressing CALL or turning off the  
station also releases the lock).  
USING ADDITIONAL STATIONS  
You can add additional stations, such as RadioShack  
Cat. No. 43-486, to your intercom system as long as they  
transmit on the same frequency. The stations and their  
box are labeled to indicate the stations’ frequency — A  
(200kHz), B (270 kHz), or C (230 kHz). Stations in the  
same box have the same frequency.  
Be sure the letter on the stations you plan to add match-  
es the letter on your current stations. If you want to set up  
a separate intercom system, however, be sure it operates  
on a different frequency.

CARE AND MAINTENANCE  
Your RadioShack Two-Station FM Wireless Intercom is  
an example of superior design and craftsmanship. These  
suggestions will help you care for your intercom stations  
so you can enjoy them for years.  
Keep the stations dry. If they get wet, wipe  
them dry immediately. Liquids might con-  
tain minerals that can corrode the electron-  
ic circuits.  
Use and store the stations only in normal  
temperature environments. Temperature  
extremes can shorten the life of electronic  
devices and distort or melt plastic parts.  
Keep the stations away from dust and dirt,  
which can cause premature wear of parts.  
Handle the stations gently and carefully.  
Dropping them can damage circuit boards  
and cases and can cause the stations to  
work improperly.  
Wipe the stations with a damp cloth occa-  
sionally to keep them looking new. Do not  
use harsh chemicals, cleaning solvents, or  
strong detergents to clean the stations.

Modifying or tampering with the intercom stations’ internal  
components can cause a malfunction and might invalidate  
your intercom’s warranty and void your FCC authorization  
to operate it. If your intercom stations are not performing  
as they should, take them to your local RadioShack store  
for assistance.  
THE FCC WANTS YOU TO KNOW  
Your intercom stations might cause TV or radio interfer-  
ence even when they are operating properly. To deter-  
mine 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 your stations away from the receiver  
• Connecting your stations to outlets that are on a dif-  
ferent electrical circuit from the receiver  
• Contacting your local Radio Shack store for help  
If you cannot eliminate the interference, the FCC requires  
that you stop using your stations.
