CHAPTER 5 Initial Equipment Setup Unpacking Unpacking your RTS System. Below are the items that should come with your base station and each beltpack. Contact the shipper or your dealer immediately if anything is damaged or missing. Fill out the registration card and return it to Bosch to register the unit.
22 Initial Equipment Setup BTR-800, TR-800, TR-825 Antenna Connection The base station is supplied with the two antennas. One 1/2wave antenna for Transmit and one 1/2-wave for Receive. The antennas have TNC male connectors. 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.
BTR-800, TR-800, TR-825 Initial Equipment Setup 23 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. FIGURE 15.
24 Initial Equipment Setup BTR-800, TR-800, TR-825 FIGURE 17. Antenna Placement Improving Reception and Increasing 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 enhanced by remoting the 1/2-wave antennas. The 1/2-wave antennas are ground plane independent.
BTR-800, TR-800, TR-825 Initial Equipment Setup 25 Base Station Set-up FIGURE 18. Base Station – Rear Panel Location Transmit Switches Locate the base station with the front and rear of the unit accessible so that switches may be set and connections made. Place the transmit and receive antenna’s on the base station. Make sure the color band match the color dot near each antenna. See “Antenna Placement” on page 22 for more information on choosing a proper operating location.
26 Initial Equipment Setup BTR-800, TR-800, TR-825 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).

28 Initial Equipment Setup BTR-800, TR-800, TR-825 Dual Listen Functionality The base station’s main audio board has the option of placing additional parts to enable dual listen. Dual listen allows the mixing of the intercom channels. The mixing will occur locally, within the base station, and is only heard on that base station’s beltpacks. The user will have the ability to enable/disable the mix of I/C A into I/C B or vise versa. If you have TR-825 beltpacks, there is no need to install this base option.
BTR-800, TR-800, TR-825 Initial Equipment Setup 29 Auxiliary Input/Output The input and output 3-pin XLR auxiliary connections are for supplying additional balanced audio into and receiving balanced audio from the base station. The output auxiliary connection only interfaces to intercom B. However, there is an internal switch to control the routing of the input auxiliary audio. See “Internal Auxiliary Input Routing Switch” on page 29. The input and output auxiliary audio is global.
30 Initial Equipment Setup BTR-800, TR-800, TR-825 FIGURE 24. Base Station – Rear Panel Stage Announce / Relay Contacts The stage announce output connector is where the audio exits the base when any of the beltpacks press the [SA] button. The output is balanced audio though a male 3-pin XLR. The state announce output level is set at the factory for 2 Vrms typical output at rated deviation into 600 Ohms. This should be adequate for most applications.
