Introduction
General Description
Telex RadioCom™ BTR-80N UHF Synthesized Wireless In--
tercom system offers reliable, high-performance, high-fidelity
full-duplex communications delivered with minimum spec--
trum usage.
The BTR-80N system includes the BTR-80N frequency agile
base station, working with up to four TR-80N or TR-82N fre--
quency agile beltpacks operating in full-duplex communica--
tions. An almost unlimited number of beltpacks may be used
with a base station if the beltpacks are in Push-to-Tx mode
(half-duplex).
The BTR-80N system incorporates two audio channel opera--
tion, permitting the beltpack operator to choose between two
separate audio channels of communication, with the base sta--
tion tracking the beltpack selection. This allows the user the
flexibility to create a party-line and a private line within the
same beltpack.
The BTR-80N system is perfectly suited for stand-alone oper--
ation and can also interface with Audiocom® (Telex), RTS®
TW, Clear-Com®, as well as RTS®, Matrix systems and other
4-wire intercom systems. In addition to the external intercom
systems interfaces listed above, the system provides connec--
tions for auxiliary balanced audio input and output, as well as
wireless talk-around (WTA) and stage announce (SA) fea--
tures.
The RadioCom™BTR-80N system has been designed for re--
liable, efficient operation. Operating in the 482 to 722 MHz
range the units operate reliably at line-of-sight distances of
1,000 feet. With available antenna systems from Telex, the ef--
fective operating range can be extended. The high-efficiency
beltpacks provide between 8 and 11 hours of uninterrupted op--
eration using NiMH rechargeable battery packs.
System Features
•Frequency-agile base station and beltpacks. No external
computer/device required to select frequencies.
•Backlit base-station LCD allows the user to easily moni-
tor the beltpack’s status as well as change base station fre-
quencies.
•Squelch adjust on BTR-80N and TR-80N, TR-82N
beltpacks.
•Beltpack's battery level displayed on the base station and
in beltpack's menus.
•ClearScan™ function on base station and beltpack to au-
tomatically find the best channels on which to operate.
•Full-duplex (simultaneous talk and listen) or Push-to-TX
(half-duplex) operation.
•Compatible with Audiocom® (Telex), RTS® TW, Matrix,
Clear-Com® , and other wired intercom types.
•Two independent channels of intercom audio with the
ability to operate partyline and RTS Matrix on the same
intercom channel at the same time.
•WTA (Wireless Talk Around) beltpack control. This fea-
ture allows beltpacks to talk to each other, but their audio is
lifted from any wired system connected to the base station.
•SA (Stage Announce) beltpack control. Allows the user to
direct their audio to a jack on the back of the base for P.A.
systems or other external audio systems.
•Relay contact closure on the base when the SA button is
pressed.
•TR-82N features two audio channel binaural operation in
either stereo or mono mode.
•TR-82N has 1/8 inch (3.5mm) jack for auxiliary input
from another audio source, such as an IFB, iPod®,or
other similar device.
•Beltpack units contained in a weather and shock resistant
die cast magnesium case.
•Convenient IEC power connector on the base station so
the unit can plug directly to outlets. No in-line or wall
plug power supply.
•Base station has option for DC on the receive coaxial ca-
ble line for powering in-line low noise amps.
•Dark mode settable on TR-80N and TR-82N beltpacks.
This shuts down all LEDS.

Antenna Connection
The base station is supplied with two (2) antennas. One
1/2-wave antenna for Transmit and one 1/2-wave for Receive.
The antennas have TNC male connectors.
The frequency range of the antennas should match the receiver
and transmitter of the base station. Match the color code on
the antenna with the color code on the base station.
Attach the transmit 1/2-wave antenna to the antenna input re--
ceptacle labeled “Transmit” on the right side of the rear panel.
The antenna should be vertically aligned.
Figure 5-1
Attaching Transmit 1/2-Wave Antenna
Attach the receive 1/2-wave antenna to the antenna input re--
ceptacle labeled “Receive” on the left side of the rear panel.
The antenna should be vertically aligned.
Figure 5-2
Attaching Receive 1/2-Wave Antenna
Antenna Polarization
The Telex Wireless Intercom System is “Vertically Polarized”.
This means both the transmitting and receiving antennas
should operate in the vertical position.
Figure 5-3
Vertically Polarized Antennas
Distance between Antennas
The distance between the base station’s receive and transmit
antennas is not adjustable when the antennas are connected di--
rectly on the back of the unit.
The antennas can be remotely mounted for a better signal
path. A Telex coax assembly with remote antennas may be re--
quired. See "Accessory" section for ordering information.
NOTE: If your base station is to be located in a shielded rack
mount enclosure or other poor RF location, you must remotely
mount the 1/2-wave antennas with coax assemblies. See "Ac--
cessories and Replacement Parts" section for remote mounting
hardware.
Antenna Placement
Proper antenna placement probably has the most effect on
your TELEX Wireless Intercom System’s overall perfor--
mance. The following suggestions will result in optimum per--
formance.
Proper placement of the beltpack can be critical. The antennas
should be in the open. Bending the antennas up and placing
the beltpack in a pocket, etc., will reduce system distance.
It is suggested that the unit be worn on the belt or pocket with
both antennas vertical for best operating range and perfor--
mance.
