The configuration, shown in Figure 9, the PS2001L Combine/Isolate switches are set to the Combine position. With this
setting all intercom stations connected to the one (1) PS2001L are combined on intercom channel 1 and all intercom stations
connected to the other PS2001L are combined on channel 2. Typically, a headset is connected to the front panel of the US-
2002, and the US-2002 dip switches are set to monaural operation (default setting) so that both intercom channels are heard in
the monaural headphones (binaural headphone operation is not supported). The PA-KP local power supply is optional. When a
PA-KP is connected, the US-2002 automatically disconnects from system power. Since the US-2002 is not drawing power
from the intercom system, more system power is available for additional belt packs, etc.
