Local Power Input (BP-2002 only) Normally the BP-2002 is powered from the intercom system and will turn on with the intercom system. The BP-2002 belt pack may also be powered from an optional power supply (18-30 VDC) connected between pin 2 (+) and pin 1 (-) of the intercom channel connector. 8. INTERCOM CHANNEL CONNECTORS: On the BP-1002, the intercom channel is connected via a pair of 3-pin connectors (one male and one female).
Changing Modes of Operation: Perform the following steps to change the mode of operation. 1. Both the Talk and Call indicators should be off. 2. Press and hold the Talk key, then press and hold the Call key, then release both keys. The Call indicator should now glow red. (The number of beeps heard in the headset indicates the current mode of operation.) 3. Press the Call key to change to the next mode of operation.
INTERNAL SWITCHES, JUMPERS AND ADJUSTMENTS There are several internal switches, jumpers and an adjustment that affect operation. These are described below. To gain access to the switches, jumpers and the adjustment, disconnect all power and line connections. Remove two screws from the top of each side and two screws from bottom of each side. Switch, jumper and adjustment locations are shown in Figure 2. Figure 2. Internal Switches, Jumpers and Adjustments.
NOTE: On the BP-1002, jumper JP6 must always have pins 2 and 3 shorted. Side Tone Adjustment (R145) The side tone adjustment is accessible either internally (refer to Figure 2) or by removing the belt clip mounting screw (callout 5 in Figure 1). To adjust the level of your own voice heard in the headphones, tap the Talk button once to turn on the headset microphone. Then, use a small flatblade screwdriver to increase or decrease your voice level while talking into the microphone.
