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.
