Telex RadioCom BTR-200 II Operating Instructions Manual page 5

The system operates on selected frequencies
within the 150-216 MHz band.
The BTR-200 system is fully compatible with
a number of other wired intercom manufactur-
ers units. See the BTR-200 Setup Section for
additional information.
The Telex Model's TR-200 and TR-200P
Belt-pack Transceivers, are designed with one
transmit and one receive channel.
The TR-200 Transceiver operates in the con-
tinuous transmit mode with the audio, to talk,
activated by a switch. As many as four TR-200
belt-pack transceivers can operate in a fully
duplex network with one Telex Model
BTR-200 or BTR-200 II Base Station.
The TR-200P Transceiver operates in the
Push-to-transmit mode (the transmit and talk
function are activated together). Any number
of TR-200P transceivers can be used in a
half-duplex network with one BTR-200 or
BTR-200 II Base Station. Operate only one
transmitter at a time. Attempting to use two
transmitters simultaneously on the same chan-
nel will cause interference.
