2.8.6 Actions Taken for Low Battery Charge Level
Decreasing in remaining battery level during battery driving
If the battery power remains only a little, the power LED on N22A illuminates in orange or red to
inform that the battery should be charged
If so, perform either of the following operations depending on situations:

Possible supply of AC power through AC outlet
Connect the AC adapter to an outlet, or connect the car adapter to a cigar lighter
receptacle.
Then the battery charge LED illuminates in orange and battery charge is started.

When power outlet or car cigarette socket is not available
Close applications currently in use, then turn off the power of the N22A.

In the lower battery charge level, do not access to a card such as a memory card if used.
Accessing to the card may fail because the time taken for the accessing can be longer than
the full discharging time. If the battery is discharged fully before data storage, the data is lost.
