BATTERIES
When using the AccuMap 12 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. A message shows on the
screen about a minute before it shuts down.
When switching from external power to the batter-
ies, 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.
