Owners / Users Manual

(Preliminary Information)

General Description:

The Telex model BTR-1 base station transceiver is a
component of the BTR-1 wireless intercom system.
The BTR-1 is intended for use as a rack mountable
wireless full duplex intercom radio for use in a
professional installation such as television or cinema
production.

Each BTR-1 base station can be used with one TR-1.
The BTR-1 transmits within the 482 to 607.9 MHz
range (TV Channels 16-36). It receives in the 614.1
to 746 MHz range (TV Channels 38-59). The BTR-1
transmitter operates on a single frequency within an 18
MHz wide section of the transmit frequency range.
The receiver also operates on a single frequency within
an 18 MHz wide section of the receiver frequency
range.

Typical transmitter conducted output power is 50 mW.

Operating frequencies can be selected from pre-set
groups or the user can select special operating
frequencies within the 18 MHz wide allotments.

The transmit and receive antennas may be screwed
onto the BTR-1 via the TNC Female connectors on the
back of the unit. Always make sure the color dot on
the back of the base near the antenna jack matches the
color of the antenna.
