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 mo unt 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 t hey are c onnected to t he 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 pro­duces feedback which creates a squealing sound.

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.

To prevent electric shock, one blade on the

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.

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 sam e frequency. The stations and their
box are labeled to indicate the stations’ frequency — A
(200kHz), B (270 kHz), or C (230 kHz). St ations in the
same box have the same frequency.

Be sure the letter on the stat ions you plan t o add match­es 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 an d crafts man ship. 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 immedia tely. Liquids might con­tain minerals that can corrode the electron­ic circuits.

Use and store the st ations only in normal
temperature environments. Temperature
extremes can shorten t he life of ele ctronic
devices and distort or melt plastic parts.

Keep the stations away from d us t and dirt ,
which can cause premature wear of parts.

Handle the stations gently and carefully.
Dropping them can damag e circuit boards
and cases and can cause t he stations to
work improperly.

10

Wipe the stations with a da mp cloth o cca­sionally to keep them look ing new. Do not
use harsh chem icals, cleanin g sol v ents, 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 performin g
as they should, take them to your local RadioShack store
for assistance.

THE FCC WANTS YOU TO KNOW

Your intercom stations might c ause TV or radio interfer­ence even when they are 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 your stations away from the receiver

• Connecting y our 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.
