Initial Equipment Set-Up Unpacking Unpack your RadioCom System. A system package should contain the following Items: Contact the shipper or your dealer immediately if anything is damaged or missing. Fill out the regis- tration card and return it to T elex to properly regis- ter your unit. Antenna Information Antenna Connection The base station is s[...]

Attach the transmit 1/2-wave antenna to the antenna input receptacle labeled “T ransmit” on the left side of the rear panel. The antenna should be vertically aligned. Figure 10 Attaching T ransmit 1/2-W ave Antenna Antenna Polarization The T elex W ireless Intercom System is “V ertically Polarized”. This means both the transmitting and re- [...]

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” be- tween the BTR and TR are unobstructed. Y ou should be able to visibly locate the antennas at all times for best performance. Figure 13 Distance Between base station and beltpack Figure 14 Keeping S[...]

Figure 16 Antenna Placement Improving Reception and Incr easing Range Keeping the distance from the base station and beltpack as short, and unobstructed as possible will produce the most reliable performance. The base station is supplied with two antennas. This should provide satisfactory system performance in most applications. System range can be[...]

Base Station Set-Up Location Locate the base station on a level surface with the rear of the unit facing you. See “Antenna Informa- tion” section for more information on choosing a lo- cation. Rack Mounting T wo kits are available for rack mounting the base station. The first kit rack mounts a single base sta- tion in a 19" rack. The secon[...]

RF T ransmit Mode Switch 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). In the Continuous mode the RF transmitter will be on at all times regardless of whether the [...]
