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 BTR-800 UP ON/O.M. 2 WIRE 2 WIRE VOL IN IN OFF ClearScan 1 2 3 4 OUT OUT SA WTA Te le x A B BAT/OM TALK SELECT 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.
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. Attempting to operate the wireless intercom system through or around walls, ceilings, metal objects, etc. will reduce system range and 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.

Internal Transmit Switches Intercom Switch Internal to the BTR-800 are two transmit switches which enable a user to turn on or off the two transmitters individually. See Figure 19 for the location. The top cover of the base station must be removed for access. The switch closest to the front panel controls transmitter 1 (audio channel A). The switch behind that is transmitter 2 (audio channel B). The default switch position is to the left if you are facing the front of the base station.

Dual Listen Functionality They will also have the ability to control the level of the mix (-4 dB to -24 dB down from main channel). Removing two surface mount resistors and installing two SPDT switches and two potentiometer enables dual listen. The parts to be installed are shown in Table 1. The two resistors on the board to be removed are in Table 2. The base stations's main audio board has the option of placing additional parts to enable dual listen.
Auxiliary Input/Output The output auxiliary audio is also taken from the intercom B base local headset, beltpack(s), headsets, and any wired intercom connected to the base station. A modification document is available from Telex Communications for those who wish to modify the base station so that auxiliary input audio is heard only locally; base local headset and beltpack(s) headsets.

Section 9 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.
