Att (Front End Attenuator); Receive Battery Saver Setup - Yaesu VX-3E Operating Manual

The attenuator will reduce all signals (and noise) by 20 dB, and it may be used to make
reception more pleasant under extremely crowded conditions.
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 3: ANT.ATT.
Note: Do not forget to pull the DIAL knob to rotate the DIAL knob.
3. Press the [ TXPO ] key momentarily to enable adjustment of this
Set Mode Item.
4. Rotate the DIAL knob to change the setting from "OFF" to "ON".
5. When you have made your selection, press the PTT switch to
save the new setting and exit to normal operation.
6. If you wish to disable the attenuator, just repeat the above procedure, rotating the
DIAL knob to select "OFF" in step "4" above.
When the attenuator is activated, the Operating Mode
icon (AM or FM) will blink on the display.
An important feature of the VX-3R/E 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/E 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: SAVERX.
Note: Do not forget to pull the DIAL knob to rotate the DIAL knob.
3. Press the [ TXPO ] key momentarily to enable adjustment of this
Set Mode Item.
4. Rotate the DIAL knob to select the desired "sleep" duration. The
selections available are 200 - 1000 ms (100 ms/step), 1 - 10
seconds (1 sec/step), or
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.
