2.8.5 Replacing Battery

If a battery of an invalid type is substituted for the old one, it may explode. Always use a spare
battery of an option. For used batteries, see "6 Recycling Batteries".
 Prepare a new battery valid for the N22A model to be used.
 Do not disassemble batteries.
 Batteries are consumables. Repeating charging and discharging a battery causes its charging
ability to decrease.
 If the full discharging time becomes shorter, initialize the battery. If the time cannot be
recovered still, replace the battery with a spare.
To replace the battery, follow the procedure below:
1
Leave N22A in the power-off state and unplug the AC adapter.
2
Release the LCD display lock, and then open the LCD display panel.
See "Opening/Closing LCD Display Panel and Setting Tablet Mode" in "Chapter 2 Uses of N22A")
