When Installing the Unit
Never plug in or remove the power supply • 
plug with wet hands, as doing so may 
cause electric shock.
When unplugging the power supply cord, • 
be sure to grasp the power supply plug; 
never pull on the cord itself. Operating the 
unit with a damaged power supply cord 
may cause a fire or electric shock.
When moving the unit, be sure to remove • 
its power supply cord from the wall 
outlet. Moving the unit with the power 
cord connected to the outlet may cause 
damage to the power cord, resulting in 
fire or electric shock. When removing the 
power cord, be sure to hold its plug to 
pull.
Do not block the ventilation slots in the • 
unit’s cover. Doing so may cause heat to 
build up inside the unit and result in fire.
Avoid installing the unit in humid or dusty • 
locations, in locations exposed to direct 
sunlight, near heaters, or in locations 
generating sooty smoke or steam as doing 
otherwise may result in fire or electric 
shock.
When the Unit is in Use
Do not place heavy objects on the unit as • 
this may cause a fall or break the unit and\
or additional objects which may result in 
personal injury and\or property damage.
Make sure that the volume control is set • 
to the minimum position before power is 
switched on. Loud noise produced at high 
volume when power is switched on can 
impair hearing.
Do not operate the unit for extended • 
periods of time with the sound distorting. 
This is an indication of a malfunction, 
which in turn can cause heat to generate 
and result in a fire.
Contact your dealer in regards to how to • 
correctly clean the unit. If dust is allowed 
to accumulate in the unit over a long 
period of time, a fire or damage to the unit 
may result.
If dust accumulates on the power supply • 
plug or in the wall AC outlet, a fire may 
result. The power supply plug cleaned 
periodically with a dry cloth. Also ensure 
that the power supply plug is always 
securely inserted into the wall.
Switch off the power, and unplug the • 
power supply plug from the AC outlet for 
safety purposes when cleaning or leaving 
the unit unused for 10 days or more. Doing 
otherwise may cause a fire or electric 
shock.
