When the transmit key is activated this indicator lights up to show that the audio panel is in the transmit
mode.

7 - ICS Switch
This switch selects the ICS mode. In the “up” position the audio panel is connected to the common ICS
buss. This enables the audio panel to communicate with any other audio panels also connected to the
common ICS buss. In the “center” position ( OFF ) the audio panel is disconnected from all other panels.
In the “down” position ( HOT ICS ) the headphone mic becomes active and its signal is fed into the ICS buss
without having to depress the ICS key switch. This provides for “ hands-off ” ICS operation.
