Cleaning and maintenance
•   Before you clean or maintain the device, power it off, and 
disconnect it from the charger.
•   Do not use any chemical detergent, powder, or other chemical 
agents (such as alcohol and benzene) to clean the device or 
charger. These substances may cause damage to parts or 
present a fire hazard. Use a clean, soft, and dry cloth to clean the 
device and charger.

and humidity. Do not touch the device or the charger with wet 
hands. Doing so may lead to short circuits, malfunctions, or 
electric shocks.
•   Avoid collision, which may lead to battery leakage, device 
malfunctions, overheating, fire, or explosion. 
•   Do not place magnetic storage media, such as magnetic cards 
and floppy disks, near the device. Radiation from the device may 
erase the information on magnetic storage media.
•   Do not expose your device, battery, or charger to extreme heat 
or cold. These environments may interfere with proper function 
and may lead to fire or explosion. Battery performance is affected 
at temperatures lower than 0°C.
