Safety Precaution
Back Panel LEDs
Power source should be removed before cleaning switches. Do not use wet rags to wipe
switches and clean switches with liquid.
The following precautions should be followed to avoid equipment damage and personal injury
caused by improper use:
Do not place switches near water or in a wet environment, and prevent water or moisture
from entering switch chassis.
Do not place switches on an unstable case or table, since the dropping would cause serious
harm to switches.
Maintain good indoor ventilation and clear air holes of switches.
Switches shall work normally under correct voltage, so make sure the operating voltage
agrees with the voltage marked on switches.
To reduce the risk of electric shock, do not remove its enclosure when a switch is working,
and don't do so at will even if it is not powered.
