Rf Transmit Mode Switch; Intercom Type Switch; Dual Listen Switches - Telex RadioCom BTR-500/600C Operating Instructions Manual

RF Transmit Mode Switch

Allows the operator to select three different types of
transmitting modes; continuous transmit, transmitter
off, or remote transmitter. For most operations,
place the transmitter switch in the "CONT" position
(Continuous mode).
In the Continuous mode the RF transmitter will be
on at all times regardless of whether the portables
are on or not.
In the Remote mode, the only time the base can
transmit is when a portable unit is turned on.
In the Off mode the base station will not transmit to
the remote belt-packs. This mode might be used if
the base is to be an intercom system monitor station
only.

switches do not affect the audio in the intercom
lines into the base station.
