AUTOMATIC FEEDBACK CONTROL ( AFC )
If acoustic feedback would occur while PTT or INTER are on (caused, for instance, by the
opening of a door or window), the equipment will detect and automatically fi x the issue
by decreasing the volume. After the event takes place, the equipment will attempt to rise
the volume back to the level defi ned by the user, as long as AFC is not triggered again.
ENERGY SAVING FEATURES (Automatic Shut Down, ASD )
Partial Shut Down (PSD)
The equipment constantly tracks the incoming voltage status. If the incoming voltage
drops below 13 VDC, after 20 seconds of inactivity the equipment activates PSD mode.
This change is indicated by the turning off the keyboard’s backlights. While on PSD mode,
upon pressing any key the respective function will execute normally and the equipment
will return to normal energy consumption mode.
Total Shut Down (TSD)
If the incoming voltage drops below 11 VDC, after 60 seconds the equipment will
automatically shut down any function and auxiliary load. While on TSD , upon pressing any
key the backlights will blink 3 times and the function controlled by the pressed key will not
execute.
Once the equipment detects that the incoming voltage exceeds 13VDC again, the
equipment will return to its normal operation.
HAND MICROPHONE (OPTIONAL)
The microphone has 3 buttons to control public address and siren functions.

Setting up SIREN 2 tone
SIREN 2 function allows to choose among 5 different tones (WAIL, Hi-Lo, PHASER, CHIRP,
and YELP). The selection of a SIREN 2 tone is independent from the other sirens, so that
changing tones for SIREN or AUX SIREN will not affect SIREN 2 . To set up the SIREN 2 tone,
follow the procedure described below.
1. Press and hold SIREN 2 , this will change the tone to the next option.
2. Release SIREN 2 to save the heard confi guration.
