Owners / Users Manual
(Preliminary Information)
General Description:
The Telex model TR-80N beltpack transceiver is a
component of the BTR-80N wireless intercom system.
The TR-80N is intended for use as a belt worn wireless
full duplex portable intercom radio for use in a
professional installation such as television or cinema
production.
Each BTR-80N base station can be used with one to
four TR-80N beltpacks. The TR-80N transmits within
the 614 to 722 MHz range (TV Channels 38-55). It
receives in the 482 to 608 MHz range (TV Channels
16-36). The TR-80N 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.
The RF coverage range of the TR-80N communicating
to a base station may be up to 200 meters (656 ft).
The transmitter has three selectable conducted output
power output levels; 5mW, 50mW and 100 mW. The
transmit power can also be set to automatically
reduced to the above listed power levels 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.
