RACK MOUNTING To rack mount the BTR-300 base transceiver do the following: Remove the front two #6-32 x 3/8” screws on each side of the transceiver as shown in Figure 9. Place the rack mount brackets (supplied) on either side of the unit and insert three #6-32 x 3/8” screws for each bracket.
ANTENNA INFORMATION ANTENNA CONNECTIONS The BTR-300 is supplied with two (2) anten- nas. One 5/8-wave antenna for Transmit and one 5/8-wave antenna for Transmit and one 5/8-wave for Receive. Assemble the 5/8-wave antenna by screwing the two sections together as shown in Figure 10.
Remoting Antennas: It will be necessary to remote both the transmit and receive antennas on the BTR-300 when it is rack mounted. Connect the coax cable assembly (not sup - plied), to the receive antenna receptacle and mount the 5/8-wave antenna. The antenna can be attached to either a wall mount bracket or a microphone stand bracket (not supplied).
ANTENNA POLARIZATION The Telex Wireless Intercom System is “Ver- tically Polarized”. This means both the trans- mitting and receiving antennas should operate in the vertical position.
Attempting to operate the wireless intercom system through or around walls, ceilings, metal objects, etc. will reduce system range and performance. SIGNAL REFLECTION OFF A MET AL OBSTRUCTION CAUSES RE.
LOCAL HEADSET CONNECTION Insert the headset/microphone into the 4 pin XLR connector on the front panel. See the mi- crophone connection diagram (Figure 2) if other than a Telex Headset is used.
INTERCONNECTION to a HARD-WIRED INTERCOM SYSTEM The RADIOCOM wireless system can be integrated into Telex intercom systems and most existing wired intercom systems includ- ing RTS and Clearcom.

ENABLING AUDIO PORTABLE TRANSCEIVERS Select the TR-300 portables that will be used with the BTR-300. Push in the portable enable switches that correspond to the TR-300 remotes that you will be using. The numbers of the portable stations (1, 2, 3, and 4), are the last digit of the product number on the back of the TR-300.
SETTING SYSTEM GAIN LEVELS ADJUSTING GAIN The gain may need to be adjusted for various audio conditions. The overmodulation light will indicate when the gain is too high. If the light is illuminated when you are talking, the gain is too high and will need to be decreased.
INTERCOM GAIN If the audio volume at the intercom input is too high, the light will be illuminated when the person on the intercom is talking. De - crease the gain until the light does not illumi- nate while talking at normal volume. Occasional flashing of the light is allowable.
