PAC•RT
IF Bandwidth
Timeout Timer
Battery Saver
Use the UP/DOWN arrow keys to enable/disable the operation of the
radio with a PAC•RT on this channel in conjunction with the Mode
switch. The Mode switch MUST be set up for PAC•RT in order for this option
to work. PAC•RT forces PL Transmit, Carrier Squelch Receive, and Low
Power.
The default is Disabled.
Use the UP/DOWN arrow keys to select the IF channel bandwidth.
Valid settings are 12.5 kHz, 20 kHz, and 25/30 kHz.
The default is 25/30 kHz.
Use the UP/DOWN arrow keys to enable/disable this feature. If this
feature is enabled, radio transmission will be permitted for the time
specified in the Timeout Timer field on the SYSTEM CONFIGURATION
screen (F4/F3/F2). If the radio is transmitting and the time-out timer
time runs out, the radio will be automatically de-keyed and a
continuous alert tone will be generated for as long as the PTT button
is pressed. To continue transmitting, the PTT button must be released
and the radio re-keyed.
The default is Disabled.
Use the UP/DOWN arrow keys to enable/disable this feature. If this
feature is enabled, battery life will be prolonged because the radio
powers down the receiver and synthesizer during periods of no
channel activity. If there is no activity, the radio will unmute for a
period of 10 seconds and then enter "sleep" mode. During the "sleep
period", changes in condition on the channel will not be detected. The
radio will exit sleep mode periodically to check the state of the
channel. The sleep times which apply to the different channel options
are:
1. Carrier Squelch Sleep Period and PL Sleep Period in the SYSTEM
CONFIGURATION screen (F4/F3/F2).
2. Quik-Call II Sleep Period in the QUIK-CALL II OPTIONS screen
(F4/F3/F7/F2).
Note: The default sleep periods are calculated to provide battery
savings while minimizing the chances of missing a call. If sleep
periods are increased, battery savings will also increase but the
chances of missing a call become significantly greater.
Another parameter which is important in battery saver is the Battery
Saver PL Lockout on the SYSTEM CONFIGURATION screen (F4/F3/
F2). When this feature is disabled, Battery Saver operates as described
above and in the description of PL Sleep Period on page 75.
When Battery Saver PL Lockout is enabled, PL will NOT be decoded when
the radio periodically comes out of sleep mode until carrier drops. Therefore,
a radio which enters sleep mode while a carrier is on the channel with
wrong PL or no PL will not unmute to another call until carrier drops.
This method of operation (not decoding PL) significantly increases
battery savings but can cause problems in some systems.
The default is Disabled.
