AUTOMATIC POWER-OFF FEATURE

The APO feature helps conserve battery life by automatically turning the transceiver 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 1 ~ 6 hours, as well as “APO Off.” The default condition for the APO is OFF, and here is the procedure for activating it:

1.Press and hold in the [FUNC] key for one second to enter the Menu mode.

2.Rotate the SELECT knob to recall Menu Mode No-007[APO TIME].

3.Rotate the DIAL knob to select the desired time period after which the radio will auto- matically shut down.

4.Press and hold in the [FUNC] key for one second to save the new setting and exit to normal operation.

Once you have programmed a time interval, the APO countdown timer will start whenever some front panel action (tuning, transmission, etc.) is completed.

When the APO is activated, the “ ” icon will appear at the center top 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 POWER switch for one second to turn the transceiver back on after an APO shutdown, as usual.

The APO feature will be disabled while using the Beacon or ARTS features, even if the APO feature is set to “ON.”
