• Unplug the power adapter from electrical outlets and the device when not in use.
• Do not drop or cause an impact to the power adapter.
• If the power cable is damaged (for example, the cord is exposed or broken), or the plug loosens, stop using it at once.
Continued use may lead to electric shocks, short circuits, or fire.
• Do not touch the power cord with wet hands or pull the power cord to disconnect the power adapter.
• Do not touch the device or the power adapter with wet hands. Doing so may lead to short circuits, malfunctions, or electric

• 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.
