The TOT feature provides a safety switch which limits transmission time to a pre-pro-
grammed value. This will promote battery conservation by not allowing you to make ex-
cessively-long transmissions, and in the event of a stuck
PTT
switch (perhaps if the radio
or a Speaker/Mic is wedged between car seats) it can prevent interference to other users as
well as battery depletion. As configured at the factory the TOT feature is set to 3 minutes,
and here is the procedure for activating it:
1. Press the [ F/W
] key, then press the [
0
(
SET
)] key to enter the Set mode.
2. Rotate the
DIAL
knob to select Set Mode Item 67:
TOT
.
3. Press the [ 0
(
SET
)] key momentarily to enable adjustment of this
Set Mode Item.
4. Rotate the DIAL knob to set the Time-Out Timer to the desired
“Maximum TX” time (2.5/5/10 minutes), or OFF.
5. When you have made your selection, press the PTT switch to
save the new setting and exit to normal operation.
1) When your transmission time is within 10 seconds of the Time-Out Timer
expiration, an Alert bell will provide an audible warning from the speaker.
2) Since brief transmissions are the mark of a good operator, try setting up
your radio’s TOT feature for a maximum transmission time of one minute. This will
significantly improve battery life, too!

In many areas of the world, channel congestion has required that operating channels be
closely spaced. In such operating environments, it often is required that operators use
reduced deviation levels, so as to reduce the potential for interference to users on adjacent
channels. The
VX-6R
includes a simple method of accomplishing this:
1. Press the [
F/W
] key, then press the [
0
(
SET
)] key to enter the Set mode.
2. Rotate the DIAL knob to select Set Mode Item 27: HLF.DEV .
3. Press the [
0
(
SET
)] key momentarily to enable adjustment of this
Set Mode Item.
4. Rotate the
DIAL
knob to set this Set Mode Item to “
ON
.” In this
configuration (HALF DEVIATION active), the transmitter’s de-
viation will be approximately ±2.5 kHz, and the received audio
output level will be increased, for easier listening on the narrow signal.
5. When you have made your selection, press the
PTT
switch to save the new setting and
exit to normal operation.
The “normal” setting for the deviation (when this Set Mode Item is set to
“OFF”) is ±5 kHz.
