Communicating
Setting the Channel
Each station has three channels, so you can select which
station or stations will communicate. You can also use a
station to monitor sounds near another station.
�or example, you could set a station installed in the
kitchen to Channel �, a station installed in the ��amily
room to Channel B, and a station installed in a bedroom
to Channel C. Using the station in the kitchen, you can
communicate with the station in the ��amily room by
setting the channel selector to B, or with the station in
the bedroom by setting the channel selector to C.
Set the channel switch on each station as follows:
• I�� you want all the stations to communicate with each
other, set all stations to the same channel.
• I�� you want to use a station to communicate with only
one other station, set only two stations to the same
channel.
Turning a Station On
Rotate VOLUME counterclockwise until it clicks. Then
adjust VOLUME to a com��ortable listening level. To turn
o����, rotate VOLUME clockwise until it clicks.
Calling Another Station
Be sure the stations you plan to use are turned on and
adjusted to the desired volume level.
1. Set the channel selector to the channel (�, B, or C) o��
the station(s) you are calling.
. Press CALL. Each station that is on and set to the
selected channel sounds a tone.
3. Hold down TALK and speak. When you finish
speaking, release TALK and listen ��or a response.

Notes:
• Only one party can talk on a channel at a time.

• If your voice sounds distorted, you might be speaking
too loudly or too close to the microphone.
• Set the channel selector back to your designated
