EATURE
The APO feature helps conserve battery life by automatically turning the radio off after a
user-defined period of time within which there has been no dial or key activity.
The available selections for the time before power-off are 0.5/1/3/5/8 hours, as well as
APO Off. The default condition for the APO is OFF, and here is the procedure for activat-
ing it:
1.
Press the
key, then press the
key to enter the Set mode.
2.
Rotate the
DIAL
to select the Menu Item labeled (
Save Modes #1: APO
).
3.
Press the
or
key to select the desired time period
after which the radio will automatically shut down.
4.
Once you have made your selection, press the
PTT
key to
save the new setting and exit 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 2 seconds to turn the transceiver back on
after an APO shutdown, as usual.

IMER
(
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 the
key, then press the
key to enter the Set mode.
2.
Rotate the
DIAL
to select the Menu Item labeled (
Save Modes #4: TOT
).
3.
Press the
or
key to set the Time-Out Timer to the
desired “Maximum TX” time (1 minute, 2.5 minutes, 5
minutes, or 10 minutes).
4.
Once you’re 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 improve battery life, too!
