Cleaning and maintenance
 Keep the device and accessories dry. Do not attempt to dry it with
an external heat source, such as a microwave oven or hair dryer.
 Do not expose your device or accessories to extreme heat or cold.
These environments may interfere with proper function and may
lead to fire or explosion.
 Avoid collision, which may lead to device malfunctions,
overheating, fire, or explosion.
 Before you clean or maintain the device, stop using it, stop all
applications, and disconnect all cables connected to it.
 Do not use any chemical detergent, powder, or other chemical
agents (such as alcohol and benzene) to clean the device or
accessories. These substances may cause damage to parts or
present a fire hazard. Use a clean, soft, and dry cloth to clean the
device and accessories.
 Do not place magnetic stripe cards, such as credit cards and phone
cards, near the device for extended periods of time. Otherwise the
magnetic stripe cards may be damaged.
 Do not dismantle or remanufacture the device and its accessories.
This voids the warranty and releases the manufacturer from liability
for damage. In case of damage, contact an authorized service
center for assistance or repair.
 If the device screen is broken in a collision, immediately stop using
the device. Do not touch or attempt to remove the broken parts.
Promptly contact an authorized service center.
