Cleaning and maintenance

cold. These environments may interfere with proper function
and may lead to fire or explosion.

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

parts or present a fire hazard. Use a clean, soft, and dry cloth
