Introduction The Radiocom BTR series has been designed for reliable, efficient operation. Operating in the 520 to 760 MHz range, the units operate reliable at distances of 1,000 feet. With available antenna systems from Telex, the effective operating range can be extended. The high efficiency beltpacks provide 12 hours of uninterrupted operation using standard alkaline batteries.

Initial Equipment Set-Up Unpacking Contact the shipper or your dealer immediately if anything is damaged or missing. Fill out the registration card and return it to Telex to properly register your unit. Unpack your RadioCom System.
Attach the transmit 1/2-wave antenna to the antenna input receptacle labeled “Transmit” on the left side of the rear panel. The antenna should be vertically aligned. The antennas can be remoted for better signal path. A Telex coax assembly and/or a signal splitter/ combiner with remote antennas may be required. See “Accessory” section for ordering information.
Keep the distance between the BTR and the TR as short as possible. The greater the distance, the weaker the signal. Make sure the “signal paths” between the BTR and TR are unobstructed. You should be able to visibly locate the antennas at all times for best performance. Attempting to operate the wireless intercom system through or around walls, ceilings, metal objects, etc. will reduce system range and performance.
Telex 2. Placing the BTR on top of a shelf or equipment rack unobstructed without remoting the antennas is OK. Telex 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. 1. Placing BTRs in a shelf or equipment rack and using remote antennas is OK.
Base Station Set-Up Location Locate the base station on a level surface with the rear of the unit facing you. See “Antenna Information” section for more information on choosing a location. Rack Mounting Two kits are available for rack mounting the base station. The first kit rack mounts a single base station in a 19" rack. The second kit rack mounts two base stations, side by side, in a 19" rack. Instructions are included in the rack mount kits.
RF Transmit Mode Switch Dual Listen Switches Allows the operator to select three different types of transmitting modes; continuous transmit, transmitter off, or remote transmitter. For most operations, place the transmitter switch in the “CONT” position (Continuous mode). These two switches allow the mixing of the intercom channels. The mixing of audio channels occurs locally, only at the base station and its beltpack. The switches do not affect the audio in the intercom lines into the base station.
Audio Channel Switch Intercom Type Set to Telex Selects either “IC 1 or 2" (and corresponding pins on ”IC Loop-thru"). In “Auto” position the switch allows selection of channels 1 or 2 from the beltpack. AUX Figure 25 Auxiliary Switch AUDIO CHANNEL 1 Auxiliary to I/C Switch (Program Audio) AUTO This switch is located inside the base station. Its function is to provide a user with the ability to input a third channel of listen only audio via the “AUX” jack.

Auxiliary Audio Connection Dummy Load The 6 pin telephone jack (RJ-11) may be used to supply audio into and out of the base station. RTS Matrix type intercoms may be interfaced to the base station through this jack. In the case where a wired intercom will not be used with the base station or only one of the audio channels are connected to the unit, it is important that the dummy load(s) (supplied) be installed.

Battery Installation Insure that the OFF/ON volume control knob is turned OFF. Press down the battery release latch and remove battery pack. Pack slides off in opposite direction. Replace batteries as follows: 1. Open the battery pack by inserting finger nail and lifting as shown. 2. Pull battery strap to remove low or dead batteries. 3. Load new batteries with negative end against the spring. 4. Start loading at hinged end of case. 5. Be sure strap goes under batteries and over the top of the ribs. 6.
Pre-Walk-Thru Checklist Following the instructions fully to this point you have successfully completed the following checklist: ❒ ❒ ❒ ❒ ❒ ❒ ❒ ❒ ❒ ❒ Located the base station properly. Connected power to base station transceiver. ❒ Connected the 1/2-wave antennas to the base station. Check frequency range of the antenna with the frequency of the base station by correctly matching color codes.
System Operation Base Station Operation LOCAL HEADSET VOLUME Power TALK / OVERMODULATION INDICATOR If you have followed the instructions until this point you should now be ready to turn both the beltpack and the base station “ON” HEADSET MIC GAIN VOL Place the power switch on the base station in the “ON” position. The green power on indicator LED should illuminate.
Aux OUT Adjusts the level of the base station’s audio out to the auxiliary connector. The auxiliary “OUT” control should be adjusted so that its audio is equal to other devices on the auxiliary system. The base station’s audio is always supplied to the auxiliary jack regardless of the auxiliary switch position. Dual Listen Level This control is related to the dual listen switches. It controls the level of the audio mix.
Beltpack Operation Power/Local Headset Volume Push-to-Talk/Lock-to-Talk You should now be ready to turn the beltpack “ON”. Rotate the OFF/ON Volume Control Switch on the beltpack clockwise to turn the unit on. To enable the talk function on the beltpack press and hold down on the talk button and begin talking. Releasing the talk button will discontinue the microphone audio. For continuous talk, quickly press and release the talk button. This locks on the talk function.
Specially ordered beltpack to beltpack (Mirror Image) direct communication units have their sidetone controlled by a control on the beltpack. To adjust the voice feedback to the earphone (sidetone) of these units, simply turn the control until the sidetone is at a comfortable level.

Example System Configurations Single Base Station Audiocom (Telex) System The audio out of the base station’s RCA jack is the audio channel currently switched to at the BTR-500. The audio out RCA jack on the back of this unit is used for the public address system. The unused Audiocom channel must be terminated to avoid loud feedback if audio channel two was switched to by the beltpack.

Beltpack to Beltpack System The following is an example of a beltpack to beltpack system. The two operators need to be in constant, full-duplex communication with each other in a noisy paper press environment.
System Walk-Thru Now that you have successfully “set up” your Telex Wireless Intercom System and turned on any auxiliary equipment you are ready to test the overall performance by “Walking” the Telex system through the areas in which you will be using it. The “system walk-thru” can detect problems of weak signal strength caused by: Before you begin your walk-thru, check the following: ❒ ❒ ❒ ❒ ❒ · Poor antenna location · Wrong antenna for receiver and/or transmitter.
TROUBLESHOOTING Reread the sections of this manual to make sure you have completed system set-up properly If you are unable to solve the problem, contact the dealer from whom you purchased the system for assistance. PROBLEM SOLUTION DISTORTION - System’s audio quality seems distorted at medium to high input levels. R e d u c e m i c ro p h o n e g a i n microphone gain control. by adjusting HISS - System seems to produce a “hiss” which is undesirable.
Tech Tips Codes Settings and the BTR600C Frequency Interaction While the BTR-600C and corresponding TR-600C have over 65,000 different codes that may be selected by the user, there are actually over 16 million different codes in the units. The microprocessor in each base station and corresponding beltpack has two unique numbers programmed into them from the factory.
Battery Information Nickel-Metal Hydride Batteries: These batteries can save you money in the long run, as they can be recharged. Typical battery life is 8 to 9 hours, which is about 70% of the length of time alkaline batteries last. Improper battery selection, use, installation and care are the cause of numerous wireless system failures. Alkaline Batteries: Alkaline batteries such as Mallory’s DURACELL® or Eveready’s ENERGIZER® provide the most reliable operation in wireless transceivers.
