This equipment has been tested and found to comply with
the limits for a Class B digital device, pursuant to Part 15 of
the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and
can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause
harmful interference to radio communications.

The intercoms use radio frequencies called channels to
communicate with each other. Your intercoms have four
channels. The intercoms also use sub-tones within the
channels to help eliminate interference between intercoms,
even if someone is using another intercom set to the same
channel. Your intercoms have eight sub-tones.
RadioShack’s involvement in this
program is part of the company’s
commitment to preserving our
environment and conserving our
natural resources.
The channels and sub-tones let you set each intercom so
they can:
• communicate with each other
• communicate with additional intercoms you purchase.
• not communicate with other intercoms
For example, if you have more than two intercoms installed
in your home, you can set them so the intercom you
installed at the front door communicates only with the
intercom you installed in the kitchen (so guests at the door
can announce themselves to somebody working in the
kitchen).
You must set any two intercoms to the same channel and
sub-tone for them to communicate with each other.

Each intercom has a group of DIP switches inside the
battery compartment. Use an object such as a straightened
paper clip to set the DIP switches.

You can place the intercoms on a desk or table, or mount
them directly on a wall. To mount the intercoms on a wall,
you need two screws for each intercom (not supplied), with
heads that fit into the keyhole slots on the back of the
intercom.
•
Be sure you install the
intercoms at least 10 feet away
from each other. Placing the
intercoms too close together
produces feedback (a squeal or
howl from the speakers). The
intercoms can transmit up to
200 feet line of sight.
For each intercom, follow these steps to mount it on a wall.

Keep the intercoms dry; if they get wet, wipe them dry
immediately. Use and store the intercoms only in normal
temperature environments. Handle the intercoms carefully;
do not drop them. Keep the intercoms away from dust and
dirt, and wipe them with a damp cloth occasionally to keep
them looking new.
Adjusting VOLUME on the
intercoms does not change the
intercom’s input sensitivity.
