2.8 BATTERY
The battery is the power supply built in N22A. The battery can be recharged by using the AC
adapter, optional battery charger FC-BC01N or optional car adapter FC-VA01N.
Installing the charged battery in N22A allows it to be operated without AC power.
The available time of the battery fully charged varies depending on the environment and
condition in which N22A is used. The time may be shortened if applications access to
peripheral devices frequently.
2.8.1 Notes on Batteries

Batteries are consumables. Repeating charging and discharging a battery causes its
charging ability to decrease. Batteries are not charged fully at purchase.

Charge batteries in temperature range 5 to 40ºC. Charging the battery at a higher
temperature may cause it to be deteriorated or damaged.

It takes a longer time to charge the battery fully at a low temperature than to charge it fully
at a normal temperature.

The time taken to charge the battery fully may vary depending on conditions under which
N22A is used.

At a lower temperature, N22A can operate only for a shorter period.

Batteries should be fully charged if possible. Repeating little charge and discharge of the
battery at a low battery level may cause the low remaining battery level to be erroneous.

In use of an external power, leave the battery installed in N22A. This allows the battery to
be kept in the full charge state.

If N22A is not used for a long period (two weeks or longer), remove the battery from N22A.

To remove the battery, do not make the battery pins contact with conductors including
metals and water. Short of the pins may cause the battery to be unavailable.

Save the battery in a low-temperature and dry place if saved. Do not leave the battery in a
place where the temperature exceeds 60ºC.

Do not leave the battery for three months or longer without recharging.

The battery driving time specified in the brochure and User
’
s Guide of the battery is
calculated based on the battery operation time measurement method (Ver. 1.0) defined by
the Japan Electronics and Information Technology Industries Association.
The actual battery driving time varies depending on the operation environment, the
brightness of the LCD display and the system settings.

When a vibration or shock exceeding the installation environmental conditions is applied to
the N22A with a battery installed, or a strong vibration or shock is applied to a battery itself,
the battery may damaged, resulting in smoke or fire. In this case, stop using the battery.
To use N22A only with the battery, you should often check the remaining battery level.
