CHAPTER 1
Introduction
General Description
RTS Wireless BTR-80N UHF Synthesized Wireless Intercom
system offers reliable, high-performance, high-fidelity fullduplex communications delivered with minimum spectrum
usage.
The BTN-80N system includes the BTR-80N frequency agile
base station and up to four (4) TR-80N or TR-82N frequency
agile beltpacks operating in full-duplex communications. 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 (2) audio channel
operation, permitting the beltpack operator to choose between
two (2) separate audio channels of communication, with the
base station 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 standalone
operation and can also interface with other RTS wired intercom
systems. In addition to the external intercom systems interfaces,
the system provides connections for auxiliary balanced audio
input and output, as well as wireless talk-around (WTA) and
stage announce (SA) features.
The BTR-80N system has been designed for reliable, efficient
operation. Operating in the 482 to 722MHz range, the units
perform reliably at line-of-sight distances of 1000 feet. With
available antenna systems from RTS, the effective operating
range can be extended. The high-efficiency beltpacks provide
between 8 and 11 hours of uninterrupted operation 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 monitor
the beltpack’s status and change base station frequencies.
• Squelch adjust on the BTR-80N, TR-80N, and 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
automatically 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 and Clear-
Com wired intercoms.
• Two (2) independent channels of intercom audio with the
ability to operate party line and RTS matrix on the same
intercom channel at the same time.
• WTA (Wireless Talk-Around) beltpack control. This feature
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 (2) audio channel binaural operation in
either stereo or mono mode.
• TR-82N has a 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.
• Dark mode configurable on TR-80N and TR-82N beltpacks.
This shuts down all LEDs.

Antenna Connection
The base station is supplied with two (2) antennas. One 1/2wave 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
receptacle labeled Transmit on the right side of the rear panel.
The antenna should be vertically aligned.
Attach the receive 1/2-wave antenna to the antenna input
receptacle labeled Receive on the left side of the rear panel. The
antenna should be vertically aligned.
FIGURE 10. Attaching Transmit 1/2-Wave Antenna
FIGURE 11. Attaching Receive 1/2-Wave Antenna
Antenna Polarization
The RTS Wireless Intercom System is vertically polarized. This
means both the transmitting and receiving antennas should
operate in the vertical position.
FIGURE 12. Vertically Polarized Antennas
BTR-80N, TR-80N, TR-82N Installation 21
Distance between Antennas
The distance between the base station’s receive and transmit
antennas is not adjustable when the antennas are connected
directly on the back of the unit.
The antennas can be remotely mounted
An RTS coax assembly with remote antennas may be required.
See “Accessory” section for ordering information.
NOTE: If you
r base station is to be located in a shielded
rack mount enclosure or other poor RF locations,
you must remotely mount the 1/2-wave antennas
with coax assemblies. See “Accessories and
Replacement Parts, for remote mounting hardware.
for a better signal path.
Antenna Placement
Proper antenna placement probably has the most effect on your
RTS Wireless Intercom System’s overall performance. The
following suggestions result in optimum performance.
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., reduces the system’s distance. The
unit should be worn on the belt with both antennas vertical for
best operating range and performance.
FIGURE 14. Distance Between Base Station and Beltpack
FIGURE 13. Proper Dressing of the Antenna
Keep the distance between the base station and the beltpacks as
short as possible. The greater the distance, the weaker the signal.
Make sure the “signal paths” between the base station and
beltpacks are unobstructed. You should be able to visibly locate
the base station antennas at all times for best performance.
FIGURE 15. Keeping Site Clear to Antenna
22 Installation BTR-80N, TR-80N, TR-82N
Attempting to operate the wireless intercom system through or
around walls, ceilings, metal objects, etc. reduces system range
and performance.
FIGURE 16. Operating System Near Obstructions
IMPORTANT: DO NOT mount the base station 1/2-
wave antennas on or next to: metal, such
as beams; walls with metal studs; or
equipment racks, etc. This also applies to
antennas assembled directly to the Base
Station. Mounting antennas near metal
detunes the antennas, which can result in
noise or loss of RF signal at the Base
Station. See Figure 17.

FIGURE 17. Antenna Placement
Improving Reception and Increasing Range
Keeping the distance from the base station and beltpack as short and unobstructed as possible produces the most reliable antenna
performance.
The base station is supplied with two (2) antennas. This provides satisfactory system performance in most applications. System
range can be enhanced by remotely mounting the 1/2-wave antennas. The 1/2-wave antennas are ground plane independent, so a
ground plane is not required for good performance.

Operation
This section discusses the operation and features of the BTR80N base station, opening with base operation and quick system
setup. It then discusses basic interfacing and setup of a base
station, then ends with the connection of multiple base stations
and discussion of the links between them.
Basic Operational Description
The BTR-80N narrow band wireless intercom system offers the
most comprehensive, user-friendly, and versatile set of features
available in wireless intercom systems anywhere in the world.
The base station accommodates up to four (4) full-duplex TR80N or TR-82N beltpacks, and can be used with an unlimited
number of beltpacks in push-to-TX (half-duplex) operation. In
push-to-TX mode, the unit provides a First On Latch Out feature
which allows only one beltpack transmitter to be active at a time
when multiple users are on a single base receive channel.
The base station, via the beltpacks or it’s local headset, allows
communications with other wireless or wired users. The
2-wire and 4-wire intercoms may even be used at the same time.
The wired audio interfaces to the base are:
• 2-Wire (Telex, RTS, Clear-Com) - 2 intercom channels
• 4-Wire - 2 audio channels
• Auxiliary (both input and output)
• SA (Stage Announce) (output)
• WTA (Wireless Talk-Around)/ 2 channels of private
2-wire intercom among TR-80N and TR-82N beltpacks
• Local base station headset
The base station also features:
• A relay closure activated when the SA button is pressed at
any beltpack
• Four (4) easily accessible portable connect buttons on the
front panel. Use the buttons to turn off the audio from any of
the four (4) base receivers while at the same time killing the
talk/transmitter at the associated beltpack
• 36 engineering selected, intermodulation avoiding, factory-
defined groups
• The ability for users to enter frequencies of their own via 12
user-defined groups
System Quick Start
The following is a list to quickly get a base station and beltpacks
operating.
1. Unpack the base.
2. Connect the power cord and antennas.
3. Connect the base to audio interfaces, such as: 2-wire,
4-wire, SA, Auxiliary, or local headset.
4. Press and hold MENU while powering up the base station.
5. When the base station displays FACTORY SETUP, release
MENU.
6. Unpack the beltpacks.
7. Press MENU while powering up the beltpack(s).
8. Using the UP and DOWN arrow buttons, change the
beltpack channel to an unoccupied receive channel on the
base station.
9. Press SET twice to set channel and group.
The base should now display the audio channel of the
beltpack and a battery symbol appears shortly.
10. Plug a headset into each beltpack.
11. Adjust the microphone gain in the software menu so the
overmodulation light flashes only on some of the words at
normal speech levels.
