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, which 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,
close all applications, and disconnect all cables
connected to it.
Do not use chemical detergents, powders, or other
agents (such as alcohol or benzene) to clean the device
or accessories. These substances may cause damage to
