BATTERIES
When using the AirMap 300 with batteries, the
backlights automatically turn off after 30 seconds.
(Remember, you can change the time interval.)
Pressing the PWR key turns the lights on again.
If the batteries become weak, the message shown
at right appears on the display. When the battery
voltage drops below a certain level, the unit auto-
matically turns itself off. The unit can shut off anytime after displaying the
"Low Battery" message without further notice.
When switching from external power to the batteries, a tone sounds which
alerts you to the fact that you're now on battery power.
Store your unit with the battery pack attached. Do not remove the batter-
ies. This will increase the internal memory's battery life.
