Note 1: The vibration resistance of N22A does not assure that it has sufficient strength against resonance
generated when the frequency of added vibration is close to the natural frequency of N22A.
Note 2: Use the product with an ambient temperature of from 5ºC to 40ºC in tablet mode or while the battery is
being charged.
* The specification does not assure that N22A can operate continuously under the described environmental
conditions in which N22A is installed.
In addition, if N22A is equipped with one or more NEC or commercial options, the most severe environmental
condition among those for N22A and the options is applied. Installation environment conditions for external
optional devices are different that those for the main unit, see the document that comes with each device for
detailed conditions.
When N22A is stored at high/low temperatures, the clock built in N22A may be shifted. Set the clock before
N22A is used again.
