GENERAL OPERATION
18
One use of this feature is to prevent a channel from being kept busy
for an extended period by an accidentally keyed transmitter. It can also
prevent possible transmitter damage caused by transmitting for an exces-
sively long period. Conventional channels can also be programmed with
the Penalty and Conversation timers that are described starting on
page 27.
Tone Enable/Disable
The supervisory tones (see page 48) can be enabled and disabled by
the
TONES
option switch if it is programmed. When tones are enabled
by this switch, “TONE ON” is momentarily displayed on the lower line
and a tone sounds. Conversely, when tones are disabled, “TONE OFF” is
displayed and no tone sounds. If the
TONES
option switch is not
programmed, tones are fixed in the on or off mode by dealer
programming.
Power Turn-Off Delay
Your transceiver can be installed so that the vehicle ignition switch
as well as the front panel power switch control transceiver power. If this
is the case, both the ignition switch and the front panel power switch
must be on for transceiver power to turn on.
When the ignition switch controls power, a turn-off delay of up to
254 minutes can be programmed. The delay can be overridden at any
time by turning power off using the front panel power switch or turning
the ignition switch back on. A turn-off delay allows calls to be received
for a time after the ignition switch is turned off. At the same time, advan-
tages of ignition switch control are utilized such as preventing the battery
discharge that may occur if the transceiver is left on for an extended
period (see page 51).
