Cleaning and maintenance

During storage, transportation, and operation of the device, keep it dry and
protect it from collision.

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.

If the device is not going to be used for an extended period of time, power it off,
and remove all cables connected to it.

If anything unusual occurs (for example, if the device emits smoke or any unusual
sound or smell), immediately stop using it, power it off, remove all cables
connected to it, and contact an authorized service center.

Do not trample, pull, or excessively bend any cable. Doing so may damage the
cable, causing the device to malfunction.

Before you clean or maintain the device, stop using it, stop all applications, and
disconnect all cables connected to it.

