Power adapter safety 

 

The power plug is intended to serve as a disconnect device. 

 

For pluggable devices, the socket-outlet shall be installed near the devices and 

shall be easily accessible. 

 

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 it is damaged, take it to 

an authorized service center for inspection. 

 

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 shocks. 

 

If your power adapter has been exposed to water, other liquids, or excessive 

moisture, take it to an authorized service center for inspection. 

 

Ensure that the power adapter meets the requirements of Clause 2.5 in 

UL60950-1 and has been tested and approved according to national or local 

standards. 

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. 

 

Do not use any chemical detergent, powder, or other chemical agents (such as 

alcohol and benzene) to clean the device or accessories. These substances 

may cause damage to parts or present a fire hazard. Use a clean, soft, and dry 

cloth to clean the device and accessories.
