OPERATION
Basic Two-Way System
The basic two-way intercom system includes two stations each with a VOLUME
control, a hands free or PTT mode select rocker switch, PTT indicator LED, and PTT
button. The ICA700 hands free intercom can transmit and receive from all stations.
The system automatically controls which station is in transmit mode.
Two optional configurations will not have the mode select rocker switch
installed:
Intercoms that have the Push-To-Talk Only option must have the PTT button
pressed to transmit.
Intercoms that have the Hands Free Only option are voice activated to transmit.
Basic Three or Four-Way System
The basic three or four-way system operation is the same as the basic two-way
system. (More than four intercom boxes can be connected when using the ICA700.)
External Microphone (Option)
The external microphone option provides a separate hands free microphone that is
mounted away from the station box. When the external microphone cable is connected
the station box internal microphone is disabled. Make sure the mode select rocker switch
is placed in the hands free position. The basic system check should be performed prior
to connecting the external microphone.
