Preparation

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.

•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).

• 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.

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 315/16 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. #
