An important feature of the
VR-160
is its Receive Battery Saver, which “puts the radio to
sleep” for a time interval, periodically “waking it up” to check for activity. If somebody is
talking on the channel, the
VR-160
will remain in the “active” mode, then resume its
“sleep” cycles when the signal drops. This feature significantly reduces quiescent channel
battery drain. You may change the amount of “sleep” time between activity checks using
the Set Mode:
1.
Press and hold in the [
BANK
] key for one second to enter the Set mode.
2.
Rotate the
DIAL
knob to select Set Mode Item 42:
RX SAVE
.
Note
: Do not forget to pull the
DIAL
knob to rotate the
DIAL
knob.
3.
Press the [
BANK
] key briefly to enable adjustment of this Set
Mode Item.

DIAL
knob to select the desired “sleep” duration.
