System Options
Handheld Microphone Option
This option is for installations in high noise areas. The microphone plugs into a
receptacle on the station box. The system can be keyed to transmit with the microphone
switch or the PTT button on the station box.
Remote Station with PTT Button Option
This option is for installations where a remote station with hands free operation is
not required. The PTT button will have to be pressed for the remote to transmit.
Foot Switch Option
This option requires the installation of a single-pole single-throw foot switch
(not supplied with intercom). A two conductor cable is wired at the foot switch and
connected at the station box with a 2-pin Molex connector. The system can be keyed
to transmit with the foot switch or the PTT button on the station box.
