Vertex Standard VXA-700 ユーザーズマニュアル

r Press the 

 key again to enable adjustment of this

Menu Item.

r Rotate the DIAL selector knob to select the desired

time period after which the radio will automatically
shut down.

r When you have made your selection, press the 

key to save the new setting, then press the PTT key
repetitively until the radio exits to normal operation.

When the APO is activated, the “

” icon will appear at

the center bottom on the LCD. If there is no action by you
within the time interval programmed, the microprocessor
will shut down the radio automatically.

Just press and hold in the 

(PWR) switch for 3 seconds

to turn the transceiver back on after an APO shutdown, as
usual.

The TOT feature provides a safety switch which limits
transmission to a pre-programmed value. This will pro-
mote battery conservation by not allowing you to make
excessively-long transmissions, and in the event of a stuck
PTT switch (perhaps if the radio or a Speaker/Mic is
wedged between aircraft’s seats) it can prevent interfer-
ence to other users as well as battery depletion. As config-
ured at the factory the TOT feature is set to OFF, and here

is the procedure for activating it:

r Press the 

 key, then press the 

 key to activate

the Menu (“SET”) mode.

r Rotate the DIAL selector knob to select Menu Item

“4. Transmit,” then press the 

 key..

r Rotate the DIAL selector knob to select Sub Menu

Item “6. T.O.T.” then press the 

 key..

r Press the 

 key again to enable adjustment of this

Menu Item.

r Rotate the DIAL selector knob to set the Time-Out

Timer to the desired “Maximum TX” time (1 minute,
3 minutes or 5 minutes).

r When you have made your selection, press the 

key to save the new setting, then press the PTT key
repetitively until the radio exit to normal operation.

Note: Since brief transmissions are the mark of a good
operator, try setting up your radio’s TOT feature for a
maximum transmission time of 1 minute. This will signifi-
cantly improve battery life, too!
