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 as well as change base station fre-

quencies.

The BTR-700 system is perfectly suited for stand-alone operation and also can interface with Audiocom® (Telex), RTS® TW, Clear-Com® as well as RTS Matrix systems and other 4 wire communications systems. In addition to the external intercom systems interfaces listed above, the system provides connections for auxiliary balanced audio input and output.

The RadioCom™ BTR series has been designed for reliable, efficient operation. Operating in the 518 to 868 MHz range, the units operate reliably at line-of-sight distances of 1,000 feet. With available antenna systems from Telex, the effective operating range can be extended. The high efficiency beltpacks provide 12-14 hours of uninterrupted operation using standard alkaline batteries.

•ClearScan™ function on base station and beltpack to automatically find the best channels on which to operate.

•Full duplex (simultaneous talk and listen) operation.

•Compatible with Audiocom® (Telex), RTS TW, RTS Matrix, Clear-Com®, and other wired intercom types.

•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

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 8

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.

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” 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 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 with both an- tenna’s vertical for best operating range and performance.

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.

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, see Figure 13.

2.Placing the BTR on top of a shelf or equipment rack unobstructed without remoting the antennas is OK.

3.Placing BTRs in a shelf or equipment rack with the antennas mounted on the back of the BTR or the side of the rack is BAD.

Improving Reception and Increasing

Range

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.

Base Station - Rear Panel

Location

Locate the base station with the front and rear of the unit ac- cessible so that switches may be set and connections made. Place the transmit and receive antennas on the base station. Make sure the antenna’s color band match the color dot near each antenna. See “Antenna Information” section for more in- formation on choosing a proper operating location.

Power Connection

Plug the supplied power cord into the unit. The base station has an IEC power receptacle that accepts 100 – 240VAC, 50 – 60Hz. The specific receptacle type is an IEC 60320/C14. The cord it ac- cepts is an IEC 60320/C13. These cords are common and avail- able through many retail hardware/electronic stores if the cord is lost.

Transmit Switches

There are two switches located on the lower left side of the rear panel. The upper switch sets the transmit power level to high or normal. The lower switch turns the transmitter on or off.

Transmit Power

Set the power level to normal if using the beltpacks at c l o s e t o me d i u m d i s t a n ce s ( <2 0 0 f e e t, 1 6 1 m, line-of-sight) from the base station. Set the power level to high if using the beltpacks at a distance (>200 feet, 161m, line-of-sight) from the base station.

On/Off

Set the transmitter switch to on for normal use. In the off position the base station transmitter is disabled. Setting the switch to off will disables all the beltpacks from hear- ing anyone else or even their own sidetone.
