2. For each intercom, select the channel you
want to use by setting the last two DIP
switches (labeled
CH
) inside the battery
compartment to the channel you want to use.
The chart on the right shows the positions to
which you can set these DIP switches.
• If you want all the intercoms to communicate with
each other at the same time, set all intercoms to the
same channel and sub-tone (see also Step 3).
• If you want one intercom to communicate only with
one other intercom, set only those two intercoms to
the same channel and sub-tone.
3. For each intercom, select the sub-tone
you want to use by setting the first three
DIP switches (labeled
SUB TONE
) inside
the battery compartment to the sub-tone
you want to use. The chart on the right
shows the positions to which you can
set these DIP switches.
• If you want all the intercoms to
communicate with each other at the
same time, set all intercoms to the
same channel and sub-tone (see also Step 2).
• If you receive interference on a channel you selected
in Step 2, set each intercom to a different sub-tone.

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.
For each intercom, follow these steps to mount it on a wall.
1. Drill a hole slightly smaller than the screws you are
using to mount the intercoms, measure a length 3
15
/
16
inches (100 mm) from that hole, then drill a second hole.
2. Thread a screw into each hole, letting the left screw’s
head extend about
1
/
4
inch (6.5 mm) from the wall and the
right screw’s head about
1
/
8
inch (3.5 mm) from the wall.
3. Align the intercom’s keyhole slots with the mounting
screws and slide the intercom down to secure it.
4. Lift and rotate the antenna up so it stands vertically.

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.
•
Be sure all intercoms you plan
to use are turned on and
adjusted to the desired volume.
•
Be sure both the intercom you
are calling and the intercom
you are using to make the call
are set to the same channel
and sub-tone (see “Setting the
Channel and Sub-Tone” on
Page 3).
