The
VR-120D
includes a useful "Battery Saver" feature, which significantly reduces bat-
tery consumption during operating sessions where little incoming traffic is being received.
The Battery Saver "puts the radio to sleep" for a time interval programmed via the Menu;
periodically, the radio will "wake up" and check briefly (250 ms.) for activity on the cur-
rent operating frequency. If a station is found, full operation of the radio will resume.
To engage the Battery Saver, we use the radio's "Set" (Menu) mode, described in detail on
page 34:
1.
Be certain the
VR-120D
is in the "VFO" mode. Press the [
V/M
] key, if not in the VFO
mode.
2.
Press and hold in the [
FUNC
] key; while holding it in, press the [
SCAN
] key to
activate the "Set" (Menu) mode.
3.
Rotate the
DIAL
knob to select Menu #3 [SAVE].
4.
Press and hold in the [
FUNC
] key; while holding it in, rotate the
DIAL
knob to select
the desired "Sleep" time for the Battery Saver. The selections include 1/3/5/7/9 sec-
onds, and "Off."
5.
Press and hold in the [
FUNC
] key; while holding it in, press the [
SCAN
] key to exit to
the VFO mode.
Longer "Sleep" times will reduce battery consumption. However, longer "Sleep" times
also increase the possibility that you might miss a brief transmission.

Rotating the
DIAL
allows frequency tuning in steps pre-programmed at the factory. Clock-
wise rotation of the
DIAL
causes the radio to be tuned to toward a higher frequency, while
counter-clockwise rotation will lower the operating frequency.
If you rotate the
DIAL
while pressing the [
FUNC
] key, the frequency will change in 1 MHz
steps. This feature is extremely useful for making rapid frequency excursions over the
wide tuning range of the radio. This step size (1 MHz) can be changed; see the "Changing
the Channel Steps" section on page 15 for details.
