Clear-com KB-701 Remote
Speaker Station
Clear-com KB-701 remote speaker station connects to
a single channel of party-line intercom, and operates in half-duplex mode,
similar to a walkie-talkie. It features both an integral speaker and a
ushmount electret microphone with mic limiter and a push-to-talk button. The
station may be programmed via two internal dip switches to operate in four
di erent modes, activated by other stations within the intercom system. The
d i erent operating modes are activated using the callsignaling function of
another station, which allows for individual control of the speaker and
microphone.
