D Power saver duty cycle
This item sets the power saver duty
cycle — the ratio of receive circuit ON
to receive circuit OFF while standing
by. The duty cycle can be set to
AUTO, 1:4 or OFF. Setting to AUTO
conserves the most battery power.
D Battery voltage indication ON/OFF
This item sets the battery voltage
indication ON or OFF. When set to
ON, the battery voltage is indicated
for 2 sec. at power ON (LOW V, 4.5-
–16 V in 0.5 V steps). If the voltage
surpasses 16 V, “OVER V” appears
and flashes regardless of this setting.
D DTMF speed
When slow DTMF transmission
speeds are required (such as for
some repeaters) the transceiver’s
rate of DTMF transmission can be
adjusted.
D LCD contrast
This item sets function display con-
trast to one of 2 levels. “1” is for low
contrast and “2” is for high contrast.
fastest (100 msec. intervals)
slowest (500 msec. intervals)

AUTO
Selects “1:4” duty ratio
when receiving no signal for
5 sec., then “1:8” 60 sec.
after that.
1:4
Standby : 125 msec.
circuit idle : 500 msec.
OFF No power save function.
The power saver is deacti-
vated when more than 12
V DC is connected to the
[DC13.5V] jack.
