PRECAUTIONS
English
7 Wall or ceiling mounting — The unit should not be mounted on a wall or ceiling, unless specified in the Operating Instructions.
Electric Power
1Power sources — Connect this unit only to power sources specified in the Operating Instructions, and as marked on the unit.
2Polarization — As a safety feature, some units are equipped with polarized AC power plugs which can only be inserted one way into a power outlet. If it is difficult or impossible to insert the AC power plug into an outlet, turn the plug over and try again. If it still does not easily insert into the outlet, please call a qualified service technician to service or replace the outlet. To avoid defeating the safety feature of the polarized plug, do not force it into a power outlet.
3AC power cord
–When disconnecting the AC power cord, pull it out by the AC power plug. Do not pull the cord itself.
–Never handle the AC power plug with wet hands, as this could result in fire or shock.
–Power cords should be firmly secured to avoid being severely bent, pinched, or walked upon. Pay particular attention to the cord from the unit to the power socket.
–Avoid overloading AC power plugs and extension cords beyond their capacity, as this could result in fire or shock.
