(2) Operating temperature range
N22A of wide temperature type can operate in the temperature range between -20ºC
and 50ºC while N22A of other types operate in temperature range between 5ºC and
45ºC.
To allow N22A to be used in the wide temperature range (-20 to 50ºC), the main unit,
HDD and battery should all be available in the wide temperature range.
In environment at a high temperature, the main unit may be heated. If so, wear gloves
not to make your hands contact with the unit directly.
To suppress heat generation, the performance of N22A may be restricted automatically.
In environment at a low temperature, the battery driving time is shortened.
In addition, the LCD display can make responses slower.
(3) Shock resistance
The chassis of N22A is made of magnesium die-casting alloy and equipped with a hard
disk drive subjected to shock resistance.
N22A is designed to have the strength of enduring the test in which it is dropped from a
height of 90 cm to plywood or concrete floor.
(4) Vibration resistance
The vibration resistance of N22A does not assure that it has sufficient strength against
resonance generated when added vibration is close to the natural frequency of N22A.
(5) Continuous operation of N22A for long period
If N22A is operated continuously for a long period, deterioration of life parts in N22A may
be accelerated. Therefore, NEC may charge the repair of N22A defected due to
continuous operation for a long period within the warranty period.

N22A in the tablet mode or the battery charging state should be used in ambient temperature
range 5 to 40ºC.

The AC adapter can be used where the ambient temperature is -20ºC to 50ºC.

Note that, if a hard disk drive (wide temperature range type: FC-HD40KN/S) and replacement
battery (wide temperature range type: FC-BP01N/W) are mounted in models other than wide
temperature range types, they cannot be used in a wide temperature range (-20ºC to 50ºC).
IP54

Dust-proof performance:
Protection class IP5x means that a device of the class cannot completely avoid entry of dust
but the dust do not interrupt the defined operations and safety of the device.

Drip-proof performance:
Protection class Ipx4 means that a device of the class is not affected by spray from every
angle (by a spray nozzle).
Use optional dust-proof and drip-proof cables (FC-SC01N/FC-SC02N/FC-SC03N) as
connection cables for the LAN, serial, or USB ports. For the power connector or PC slot cover,
use an optional dust-proof, drip-proof cover (FC-SC04N/FC-SC05N).
For other connection ports, securely close the connector covers during operation.

When relocating the product, close the LCD panel display and fix the latches.

This product has excellent shock-proof characteristics, but prevention of damage or failure is not
guaranteed.
N22A damaged by shocks may reduce its dust-proof and drop-proof performance as well as the
shock resistance. Accordingly, it is recommend to repair damaged N22A.
