Program Interrupt DIP Switches

Program Interrupt DIP Switches
If you plan on using external program sources with the US2002, you have a choice of whether or not you want the program
audio to shut OFF on the intercom channel while you are talking. By default, program audio does not interrupt during talk. You
can change this as follows:
For channel 1 program interrupt during talk, set SW1-7 to ON.
1.
For channel 2 program interrupt during talk, set SW1-8 to ON
2.
If call signal receive is enabled (switches SW1-3 and SW1-5), incoming calls will be indicated by red-flashing Call keys. An
optional beep tone can also be used. Internal switches enable the beep tone. You can then turn the beep tone ON or OFF via the
front panel during normal operation. Enable the beep tone as follows:
Make sure the call signal receive DIP switches are ON (SW1-3 and SW1-5).
1.
For incoming call beep in a headset, set SW3-1 to OFF.
2.
For incoming call beep in speaker 1, set SW3-1 to OFF and SW3-3 to ON.
3.
For incoming call beep in speaker 2, set SW3-1 to OFF and SW3-4 to ON.
4.
The procedure to turn incoming call beep ON or OFF during operation can be found on page 29.

Monaural or Binaural Operation DIP Switches

The US2002 can be used with a single speaker or monaural headphones (single- or double-sided) for monaural operation. In
this case, all audio signals are combined and sent to the headphones and the Speaker 1 jack on the back panel. The US2002 can
also be used with two speakers for binaural operation. In this case, channel 1 is sent to the Speaker 1 jack and channel 2 is sent
to the Speaker 2 jack. Binaural headphone operation is not supported.

For Monaural operation with headphones or one speaker (factory default):

Set SW3-2 to OFF.
1.
Set SW3-5 to ON.
