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 [MON/F] key, then press the [0(SET)] key to enter the Set mode.
2. Rotate the DIAL to select Menu Item (Save Modes #2: RX SAVE).
3. Press the [MAIN] or [SUB] 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.

the sleep cycle may “Collide” with the beginning of an incoming Packet transmission,
causing your TNC not to receive the full data burst.

The VX-7R 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 conserves battery drain significantly.
To activate the Transmit Battery Saver:
1.
Press the [MON/F] key, then press the [0(SET)] key to enter the Set mode.
2. Rotate the DIAL to select Menu Item (Save Modes #3: TX SAVE).
3. Press the [MAIN] or [SUB] key to set this Menu Item to “ON” (this activating the
Transmit Battery Saver).
4. When you have completed your selection, press the PTT key to save the new setting
and exit to normal operation.
