An important feature of the
VX-5R
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
VX-5R
will remain in the "active" mode, then resume its "sleep"
cycles . This feature significantly reduces quiescent battery drain, and you may change the
amount of
"sleep" time between activity checks using the Menu System :
Press the [FfW]
key, then press the [BAND(SET)AR]
key to enter the Set mode .
Rotate the DIAL

is 200
Ms .
When you have made your selection, press the PTT key to save the new setting and

When you are operating on Packet, switch the Receive Battery Saver OFF, (is
the sleep cycle may "Collide" with the beginning of an incoming Packet trans-
mission, causing your TNC not to receive thefull data burst.
The VX-5R also includes a useful Transmit Battery Saver, which will automatically lower
the power output level when the last signal received was very strong . For example, when
you are in the immediate vicinity of a repeater station, there generally is no reason
to use
the full 5 Watts of power output in order to achieve full-quieting access to the repeater .
With the Transmit Battery Saver, the automatic selection of Low Power operation
con-
serves battery drain significantly.
Further battery conservation may be accomplished by
disabling the
BUSY/TX LED . U:
