RECEIVE BATTERY SAVER SETUP
An important feature of the VX-3R 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-3R 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
[
TXPO
]
key for one second to enter the Set mode.
2. Rotate the DIAL knob to select Set Mode Item 72:

5. When you have made your selection, press the PTT switch 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.
