Mic Kill Receive
Audiocom intercom stations, such as the US2002A, can transmit an inaudible signal to turn off the microphones in all remote
intercom stations on an intercom channel. This is useful when a remote intercom station has been left unattended with the
microphone on. The procedure to send a mic kill signal from a master station is a two-step process, so it is very unlikely
microphones are ever turned off by accident. However, you may wish to disable the Mic Kill Receive feature at the intercom
unit. You might do this, for example, if communications are of a very critical nature, where it is absolutely essential the
microphone never be remotely deactivated.
To enable the mic kill function , do the following:
>
Set DIP switch 1 to the open position.
To disable the mic kill function , do the following:
>
Set DIP switch 1 to the closed position.

Incoming Call Beep

DIP switch 3 must also be in the OPEN position if you want to activate incoming call beep to the speaker using DIP
switch 5
.
Microphone Type
If you are using a headset, telephone handset, or dynamic handheld microphone:
If the specifications indicate the microphone type is balanced , do the following:

If the specifications indicated an unbalanced microphone , do the following:

Set this switch to the closed position.
NOTE: If you are not sure, leave the switch in the open position for now. Try both positions during operations. Use the
position that produces the best audio quality at other stations.
