MISCELLANEOUS SETTING

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 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 OFF, and here is the procedure for activating it:

1.	Press and hold the		key for one second to enter the Set Mode.
2.	Rotate the DIAL knob to select Set Mode Item 102: TOT.
3.	Press the	key briefly to enable adjustment of this Set
	Mode Item.
4.	Rotate the DIAL knob to set the Time-Out Timer to the de-
	sired “Maximum TX” time. The available selections are 0.5

- 10.0 minutes (0.5 minute/step).

5.When you have completed your selection, press the PTT switch to save the new setting and exit to normal operation.

To disable the Time-Out Timer, just repeat the above procedure, rotating the DIAL knob to select “OFF” in step 4 above.

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 1 minute. This will sig- nificantly improve battery life, too!
