General Description:
Transmit and receive antennas are attached to the TR-
1. Either or both unscrew for field replacement but are
not coaxial connectors.
The Telex model TR-1 beltpack transceiver is a
component of the BTR-1 wireless intercom system.
The TR-1 is intended for use as a belt worn wireless
full duplex mobile intercom radio for use in a
professional installation such as television or cinema
production.
The TR-1 beltpack can be powered by AA Alkaline or
a Nickel-Metal Hydride Battery pack.
Each BTR-1 base station can be used with one TR-1.
The TR-1 transmits within the 614 to 746 MHz range
(TV Channels 38-59). It receives in the 482 to 608
MHz range (TV Channels 16-36). The TR-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.
The TR-1 transmit power can be set to automatically
reduced when the unit is close-in to the base station to
aid in intermodulation reduction and unnecessary
transmit power.
Operating frequencies can be selected from pre-set
groups or the user can select special operating
frequencies within the 18 MHz wide allotments.
The LCD display and buttons plus the talk function
switch, is located on the back panel.
