Cleaning and Maintenance
• The device, battery, and charger are not water-resistant. Keep them dry.
Protect the device, battery, and charger from water or vapor. Do not touch
the device or the charger with a wet hand. Otherwise, it may lead to a short
circuit, a malfunction of the device, and an electric shock to the user.
• Do not place your device, battery, and charger in places where they can get
damaged because of collision. Otherwise, it may lead to battery leakage,
device malfunction, overheating, fire, or explosion.
• Do not place magnetic storage media such as magnetic cards and floppy
disks near the device. Radiation from the device may erase the information
stored on them.
• Do not leave your device, battery, and charger in a place with an extreme
high or low temperature. Otherwise, they may not function properly and may
lead to a fire or an explosion. When the temperature is lower than 32°F
(0°C), performance of the battery is affected.
• Do not place sharp metal objects such as pins near the earpiece. The
earpiece may attract these objects and hurt you when you are using the
device.
• Before you clean or maintain the device, power off the device and
disconnect it from the charger.
• Do not use any chemical detergent, powder, or other chemical agents (such
as alcohol and benzene) to clean the device and the charger. Otherwise,
parts of the device may be damaged or a fire can be caused. You can clean
the device and the charger with a piece of damp and soft antistatic cloth.
• Do not dismantle the device or accessories. Otherwise, the warranty on the
device and accessories is invalid and the manufacturer is not liable to pay
for the damage.
• If the device screen is broken by colliding with hard objects, do not touch or
try to remove the broken part. In this case, stop using the device
immediately, and then contact an authorized service center in time.
Emergency Call
You can use your device for emergency calls in the service area. The
connection, however, cannot be guaranteed in all conditions. You should not
rely solely on the device for essential communications.
