ALERT TONES
The radio generates a number of alert tones to
indicate various events. The following section describes
the alert tones.
STANDARD TONES
Power-UP
If programmed, a tone will sound on
power-up after the radio passes the
self test.
Low Battery
A low pitch tone will sound every 130
seconds when the battery is low and
needs charging.
Carrier Control
Timer
The Carrier Control Timer (CCT)
alert is a pulsed tone signal that
sounds whenever the PTT button is
continuously pressed for a pre-
programmed length of time. After
nine seconds of pulsing the
transmitter shuts down and
communications is interrupted. To
maintain communications, release
and re-key the PTT switch. This
resets the timer and turns the
transmitter back on. The CCT is a
built-in precaution against in-
advertent use of the system.
