In Audiocom® Intercom Systems, the Mic-Kill feature is used to turn OFF any

activated microphones on a selected channel. The Mic-Kill feature is activated when

the beltpack receives a 24kHz signal from the channel. In some application the Mic-

Kill and Call Signal features are not desired and need to be disabled.

made by qualified technicians.

line connections from the beltpack.
