Section 4 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 register the unit. Unpack your RadioCom™ System. Below are the items that should come with your base station and each belt pack.
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. RadioComä MENU ClearScan UP ON/O.M. 2 WIRE TM 1 2 3 4 BTR-700 IN 4 WIRE OUT COPY DOWN PORTABLE STATION CONNECT VOLUME IN TALK/O.M.
Attempting to operate the wireless intercom system through or around walls, ceilings, metal objects, etc. will reduce system range and performance. Keep the distance between the base station and the beltacks 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.
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. 1. Placing BTRs in a shelf or equipment rack and using remote antennas is OK. RadioComä MENU ClearScan UP ON/O.M.

Section 6 System Operation Frequency Plan Overview System Quick Start The BTR/TR-700 has 36 factory defined frequency groups and 12 user-programmable frequency groups. A Group defines the base station transmit frequency and thus the receive frequency on all the beltpacks. A Channel defines a base station receive frequency and thus a beltpack transmit frequency. A base station receive channel that does not have a frequency set for it will have a dash to the right of it on the Group/Channel select screen.

Section 7 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 problem of weak signal strength caused by: Before you begin your walk-thru, check the following: ❒ ❒ ❒ ❒ ❒ ❒ Beltpack Battery Check. Set microphone gain in both the beltpack(s) and the base station.

Section 8 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. Reduce microphone gain by adjusting microphone gain control. HISS - System seems to produce a “hiss” which is undesirable. Check the gain setting on all beltpacks and the base.

Section 9 Tech Tips Frequency Interaction Unfortunately, radio frequency (RF) channels cannot be randomly selected for use in radio devices. They must be selected to avoid known frequencies in use, FCC restrictions on the location of devices, and even interference between your own RF devices. The factory defined frequencies (Groups 01A-24) selected by Telex for this RadioCom™ system are chosen to minimum possible interference.

Section 10 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.
