ETUP
An important feature of the
VX-7R
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-7R
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:
1.
Press the
key, then press the
key to enter the Set mode.
2.
Rotate the
DIAL
to select the Menu Item labeled (
Save Modes #2: RX SAVE
).
3.
Press the
or
key to select the desired “sleep”
duration. The selections available are 200 ms, 300 ms,
500 ms, 1 second, and 2 seconds, or OFF. The default
value is 200 ms.
4.
When you have made your selection, press the
PTT
key to save the new setting and
exit to normal operation.
When you are operating on Packet, switch the Receive Battery Saver OFF, as
the sleep cycle may “collide” with the beginning of an incoming Packet trans-
mission, causing your TNC not to receive the full data burst.
