Protecting your data
•
To prevent accidental loss of data, we recommend that you regularly back up any important data that
you store in the product, SIM card, and SD card.
•
To prevent the unintended disclosure of private information, always confirm the destination before
sending messages, file attachments, or any other communications, such as email.
•
To prevent the unintended disclosure of sensitive information stored in the product or the SD card, we
recommend using the product’s encryption feature (page 27).
•
Before disposing of the product or handing the product over to a third party, remove the SIM card, SD
card, and any other accessories.
•
Before disposing of the product or handing the product over to a third party, perform a factory data reset
(page 49) to erase any data stored in the product.
•
Before using Wi-Fi or Bluetooth features, take appropriate action to secure your data.
Waterproof/dustproof
•
The product is waterproof/dustproof when the interface cover is closed, and the battery is attached.
Therefore, keep water and dust away from product’s internal components, accessories, and optional
products.
•
To prevent liquids, sand, dust, or any foreign objects from entering the product, always keep the battery
cover and battery clean and make sure to firmly close the cover after opening. Take care not to get
anything caught between the cover or battery and the product.
•
If the product is exposed to water droplets, wipe them off with a dry, soft cloth and shake the product to
remove the water droplets, then dry thoroughly.
•
Do not leave any water droplets on the product. Water droplets may cause the micro USB port or headset
jack to short circuit, or create smears on the screen.
•
If the product is wet, wipe off the moisture before connecting with peripheral devices.
•
Do not dry the product with an appliance or heat source such as a microwave oven or dryer.
•
Use the optional charger while dry and do not use it in places with water such as bathrooms because it
is not waterproof/dustproof.
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.
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.
