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.
