MISCELLANEOUS SETTING

rPress the key again to enable adjustment of this Menu Item.

rRotate the DIAL selector knob to select the desired time period after which the radio will automatically shut down.

rWhen 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.

Transmitter Time-Out Timer (TOT)

The TOT feature provides a safety switch which limits transmission to a pre-programmed value. This will promote 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 interference to other users as well as battery depletion. As configured at the factory the TOT feature is set to OFF, and here

is the procedure for activating it:

rPress the key, then press the key to activate the Menu (“SET”) mode.

rRotate the DIAL selector knob to select Menu Item

“4. Transmit,” then press the key.

rRotate the DIAL selector knob to select Sub Menu

Item “6. T.O.T.” then press the key.

rPress the key again to enable adjustment of this Menu Item.

rRotate the DIAL selector knob to set the Time-Out Timer to the desired “Maximum TX” time (1 minute, 3 minutes or 5 minutes).

rWhen 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 significantly improve battery life, too!
