Stuck Mic

The SL30 helps protect you from a situation where the microphone may get stuck in the
ON or Transmit position. If the microphone is keyed for longer than 35 seconds, the SL30
will return to the receive mode on the selected frequency.
A "Stuck Mic" message will display until the transmit key is released.
Note: In an emergency situation, if the "Stuck Mic" message remains after you
have stopped keying the mic, turn the power off and then back on. You will then
get another 35 second time-out period to transmit.

Intercom Function

When two headphone and microphone jacks are connected to the SL30. Headsets can be
used in conjunction with the internal voice-activated intercom.
When you select the Intercom function with the installed selector switch, the intercom
function is enabled. The Volume control may control the headphone listening level. See the
System Mode information for setting up the Mic squelch, transmitting mic, and Intercom
volume.
