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.
