You can select between a total of three transmitter power levels on your VX-150. The
exact power output will vary somewhat, depending on the voltage supplied to the trans-

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/

battery depletion. As configured at the factory the TOT feature is set to OFF, and here is
the procedure for activating it:

Once you've made the selection you wish to use, press the PTT key to save the new
setting and exit to normal operation.
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 im-
prove battery life, too!
