Maintenance
•
When cleaning the product, make sure to turn it off.
•
When cleaning the product, wipe it with a soft, dry cloth. An alcohol-based disinfectant may be used if
necessary.
–
If the product is particularly dirty, thoroughly wring a cloth soaked in water, wipe off the dirt, and then
wipe with a dry cloth.
–
Do not clean the product with solvents such as benzene, thinner, or strong alkaline detergent because
they may affect the surface of the product.
•
If the product has difficulties reading magnetic or smart cards, clean the card readers with cleaning
cards.
Battery
•
The battery is a consumable item. Depending on the usage conditions, it may swell as it reaches the
end of its life. When the typical battery life of approximately one year or about 500 charge cycles is
exceeded, the battery deteriorates. If the battery begins to swell, or the amount of time it can be used
after a full charge becomes dramatically shorter, the battery should be replaced with a new one. Contact
your technical support representative.
•
Do not touch the terminals of the battery. Failure to observe this may cause poor contact.
•
When the battery is left installed in the product, it discharges electricity gradually in small amounts even
if the product's power is off. If left for a long period (several months or more), the battery will over
discharge and its performance may deteriorate.
•
Store the battery in environments with an ambient temperature of -20 °C to 35 °C (-4 °F to 95 °F). If the
battery is stored in other environments, battery performance and battery life may be reduced.
•
When storing or transporting the battery, make sure that the battery's terminals do not become dirty and
that no foreign objects or debris become attached to the battery's terminals.
•
If battery charging is not completed after the specified charging time has passed, remove the battery
from the product. The battery protection device may be damaged.
•
You cannot charge an installed battery if it is not recognized by the product. Make sure that you use the
specified battery.
•
Dispose properly in compliance with local waste regulations.

•
Observe the following to prevent leakage and malicious use of the password.
–
Make sure customers input the password.
–
Customers should hold the product in hand during input.
–
Customers should use their hands or body to hide the password from people nearby and security
cameras.
