• UHF Operation — The BTR-80N, TR-80N and TR-82N

operate in the UHF band from 482 to 722 MHz and

operate in specific 18 MHz frequency bands. An

industry-leading 32 frequency band combinations are

available to order.

• Frequency Agile — Choose from 1440 user selectable

frequencies in 25 KHz increments or select frequency

plans from preset intermodulation avoiding groups.

The independent 18 MHz frequency bands provide

720 TX and 720 RX selectable frequencies.

• Selectable Output Power — The BTR-80N, TR-80N

and TR-82N provide a user-selectable transmit output

power. The BTR-80N has a maximum output power

of 249 mW down to 10 mW, with an additional

setting to turn OFF transmit power to each individual

transmitter. The TR-80N and TR-82N have a maximum

output power of 100 mW down to 5 mW, with an

additional setting to turn on the AUTO “Intelligent

Power Control” feature to provide outstanding near-

far operation.

• Engineering Defined Frequency Plans — Each Narrow

Band system comes with 36 engineering selected,

intermodulation-avoiding groups of channel plans

that allow even the most uninitiated user to get the

system operational right out of the box. Telex has

done all of the work for you!

• Two-Channel Intercom Access — Hardwired intercom

channels that are run to the BTR-80N base station

can be 2-wire (Party-Line) or 4-wire (digital matrix).

These intercom inputs to the BTR-80N can be set up

to be individual per channel or they can be mixed on

a channel. Individual adjustment for IN and OUT level

control are provided in the BTR-80N front panel user

interface.

• Flexible Number of Beltpack Users per Base Station

— In full-duplex operation, the BTR-80N will support

up to 4 TR-80N or TR-82N beltpacks. By placing

TR-80N or TR-82N beltpacks in “Push-to-Transmit”

operation (half-duplex), you can expand your system

to multiple users on one BTR-80N base station.

When the TR-80N or TR-82N are placed in “Push-to-

Transmit” operation, the intelligence of the narrow

band system provides a “First-On-Latch-Out” feature

that will not allow the beltpacks to interfere with

each other when operating on the same frequency.

This feature provides future expansion possibilities

and will allow multiple users on the same channel

whose primary function is to listen all the time and

talk infrequently.

• Enhanced ClearScan™ Frequency Scan and Auto

Selection — This powerful frequency scanning and

selection feature is easily activated and progress is

easily monitored on the TR-80N, TR-82N and BTR-80N

display screens. Results are provided and users have

the option to review, accept or reject the results.

This dynamic feature allows system frequency

selection and setup in just minutes in a new or

unknown venue.

• Battery Options — The TR-80N and TR-82N beltpacks

can operate from standard alkaline AA batteries or

from the optional NiMH battery packs. Operation

on alkaline batteries provides up to 12 hours of

continuous duty and up to 10 hours on NiMH. Drop-

in chargers are available in single and four-gang

configurations.
