alert monitor switches to F1 cutting off any
transmission on F2. When switching from F2
to F1, the alert monitor listens for any tones
and alerts if the proper tones are detected. It
should be noted that the detection of tones is
very dependent on the duration of the tone...

 
10 BATTERY LIFE

received, length of each call, capacity and

low battery pulse tone is sounded. The LED
continues to flash and voice communication
deteriorates until the batteries are replaced. If
the unit is recharged without being turned off,
the low battery alert signal will continue until
the RESET button is pressed....
