Introduction
General Description
The Telex RadioCom™ BTR-1 UHF wireless intercom sys--
tems is the ultimate in reliable, high performance, encrypted
full duplex communications.
The BTR-1 system includes the BTR-1 frequency agile base
station and a TR-1 frequency agile beltpack. The BTR-1
system provides full duplex, encrypted digital communication.
The base station provides the beltpack with access to a six in--
tercom port matrix of 2-wire systems or communication to a
4-wire intercom system. The system can interface with
Audiocom® (Telex), RTS® TW, Clear-Com® 2-wire inter--
com systems as well as 4 wire communication systems.
In addition to the 2 and 4-wire intercom systems the base sta--
tion provides connections for auxiliary balanced audio input
and output, as well as relay closure and the ability for using
one of the six intercom lines as a wireless only communication
intercom. The system is also perfectly suited for stand-alone
operation.
The BTR-1 has been designed for reliable, efficient operation.
Operating in the 482 to 746 MHz range. The unit has ex--
pansion ability to add dozens of base stations to create a sys--
tem. The high-efficiency beltpack provides up to 9 hours of
uninterrupted operation using standard alkaline batteries.

Rack Mounting
The rack mounting brackets come with each BTR-1. These
brackets may be used to mount a single base station in a 19"
wide rack or mount two base stations side by side in a rack.
Figure 5-1 shows the three brackets that come with a base sta--
tion.
Rack Mounting a Single Base Station
1. Remove the four pan head screws (two on each side) clos-
est to the front panel.
2. Place the double unit side bracket on the side of the base
station you wish closest to the edge of the rack.
3. Replace the two pan head screws and use a third pan head
screw (2 supplied with base station) to screw into the up-
per middle location of the bracket.
4. Place the single unit rack mount bracket on the other side
of the base station.
5. Replace the two pan head screws and the other pan head
screw that came with the base to secure the bracket. Screw
the third screw into the upper middle hole of the bracket.
6. Use the rack mount screws (not supplied) to secure the
unit to the rack.
Figure 5-2
Rack Mounting of a Single Unit
Rack Mounting Two Base Stations
Side-by-Side
1. Remove the four pan head screws (two on each side)
closes to the front panel.
2. Place the double unit side brackets on the sides of the base
stations you wish closest to the edge of the rack.
3. Replace the two pan head screws and use a third pan head
screw (2 supplied with base station) to screw into the up-
per middle location of the rack mount middle bracket.
4. Place the dual bracket on the other sides of the base sta-
tions. Make sure the bracket is flipped so the front bend is
toward the front of the base station. As you face the rack,
the right base station will have the middle bracket front
bend high and left base station will have the bend low.
5. Replace the two pan head screws and the other pan head
screw into the upper middle hole of each bracket.
6. Use the four flat head screws (2 supplied with base sta-
tion) to secure the top and bottom of the middle brackets
together.
7. Use rack mount screws (not supplied) to secure the unit to
the rack.

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 “TRAN” on the right side of the rear panel.
The antenna should be vertically aligned.
Figure 5-4
Attaching Transmit 1/2-Wave Antenna
Attach the receive 1/2-wave antenna to the antenna input re--
ceptacle labeled “RCV” on the left side of the rear panel. The
antenna should be vertically aligned.
Figure 5-5
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 5-6
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 remoted for better signal path. A Telex
coax assembly with remote antennas may be required. See
“Accessory and Replacement Parts” section for ordering infor--
mation.
NOTE: If your base station is to be located in a shielded rack
mount enclosure or other poor RF location, you must remote
the 1/2-wave antennas with coax assemblies. See “Accessories
and Replacement Parts” section for remote mounting hard--
ware.
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 antenna’s vertical for best operating range and perfor--
mance.

ANTENNAS SHOULD BE VERTICAL

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 perfor--
mance.
Figure 5-8
Distance Between base station and beltpack
Figure 5-9
Keeping Site Clear to Antennas
Attempting to operate the wireless intercom system through or
around walls, ceilings, metal objects, etc. will reduce system
range and performance.
Figure 5-10
Operating System Near Obstructions
DO NOT - mount the base station 1/2-wave antennas on, or
next to metal, such as beams, walls with metal studs, equip--
ment racks, etc. This also applies to the antennas when assem--
bled directly to the Base Station. This will “detune” the
antennas which can result in noise or loss of RF signal at the
base station.
Keeping the distance from the base station and beltpack as
short, and unobstructed as possible will produce the most reli--
able performance.
The base station is supplied with two antennas. This should
provide satisfactory system performance in most applications.
System range can be enhanced by remoting the 1/2-wave an--
tennas.

1. Placing BTRsin a shelf or
equipment rack and using re-
mote antennas is OK.
2. Placing the BTR on top of a
shelf or equipment rack un-
obstructed without remoting
the antennas is OK.
3.Placing BTRs in a shelf or
equipment rack with the an-
tennas mounted on the back
of the BTR or the side of the
rack is BAD.

BTR-1 Operation
Basic Operational Description
The BTR-1 is a full duplex (simultaneous talk and listen) base
station that works in conjunction with a TR-1 beltpack.
The base station, via the beltpack, allows communication with
other wireless or wired users. The A, B and C buttons on
beltpack are assigned their functions at the base station. The
base station also has the ability to program the frequencies of
the beltpack over-the-air. The sidetone for the base station's lo--
cal headset and the beltpack are also adjusted at the base sta--
tion.
If base stations are being used stand alone (no 2-wire power
supply) but interconnected via the 2W interconnect cables, all
used intercom channels must be loaded or a loud squeal may
result.
System Quick Start
The following is a list to quickly get a base station and
beltpack operating.
1. Ensure the base station and beltpack are of the same
frequency bands.
2. Attach antennas to base station.
3. Power-up the base station.
4. Press <MENU> + <SET> + <UP> + <DOWN> on the
base station once it is powered up.
5. Load the base station with a AudioCom power supply
on intercoms 1 and 2 or place a load on intercoms 1
and 2.
6. Press <MENU> as powering-up the beltpack.
7. Set the encryption code on the base station.
8. Set the encryption code on the beltpack to match the
base station.
9. Set the serial number of the base station in the
beltpack.
10. The base should now indicate a battery voltage indicat-
ing the base station and beltpack are communicating.
11. Plug a headset into the base station and beltpack. Ad-
just the microphone gain on both so the
overmodulation light flashes only on the loudest ex-
pected speech level.
