14-4 CONFIG Power save
The POWER SAVE facility may be used to help the receiver to operate for longer periods of time
between battery recharging. Power save is default OFF to prevent confusion while the AR8200 is in a
“dormant” cycle as the receiver is effectively asleep and only wakes up for short periods to check for
activity before going to sleep and becoming dormant again.
&Note: While in a dormant state (waiting to cycle), the AR8200 behaves sluggishly.
When power save is ON, the AR8200 will automatically switch ‘off and on’ but the display will appear
permanently on as only the AR8200 “receive” circuitry is switched off and on (switching the receiver off
for short periods of time is what saves power!), the microprocessor is left on permanently but in a
reduced operating condition.
When activated, two parameters may be varied to affect the way the receiver behaves, these are
“DELAY” and “CYCLE”.
DELAY: This parameter determines how long the AR8200 will remain active before going to
sleep and becoming dormant and is timed from when the squelch last closed or keypad was last
used. The available range is 01 to 30 seconds plus OFF (default off). When OFF, the power
save does not operate. The key may be used as a short cut to OFF.
CYCLE: When the receiver becomes dormant (delay has expired), the cycle parameter
determines how long the AR8200 will remain dormant before its ‘wake up’ period begins. If a
transmission takes place while dormant it will be missed, if however a transmission occurs
during the wake up period, the AR8200 will continue to monitor until the transmission ends and
DELAY / CYCLE takes place again. The available range is 0.5 to 9.5 seconds (default 3.0
seconds). The key may be used as a short cut to 3.0 seconds.
The POWER SAVE parameters are setup in the CONFIG menu. To access the config menu
. ò three times to move
the cursor to the POWER SAVE “DELAY” selection point. Use the
main dial or ï ð keys to vary the delay value, the key
may be used as a short cut to OFF.
ò to move the cursor to the POWER SAVE “CYCLE”
selection point.
