For Safe Use of This Unit
m@ Use a standard electrical AC wall outlet
1. Use from an AC power source of high voltage, such as for air
conditioners, is very dangerous.
Be extremely careful not to make a connection to the elec-
trical outlet for a large air conditioner or central-heating unit
which uses high voltage, because there is the possibility of
fire.
2. ADC power source cannot be used.
Be sure to check the power source carefully, especially on a
ship or other place where DC is used.
™@ Connection and removal of the power cord plug
. Wet hands are dangerous. |
Adangerous electric shock may result if the plug is touched
by wet hands.
2. Don’t pull the power cord.
Always grasp the plug; never pull the cord itself.
mh
@ Never attempt to repair or reconstruct this unit
A serious electric shock might occur if this unit is repaired,
disassembled or reconstructed by unauthorized persons, or if
the internal parts are accidently touched.
@ For families with children
Never permit children to put anything, especially metal, inside
this unit. A serious electric shock or malfunction could occur if
articles such as coins, needles, screwdrivers, etc. are inserted
through the ventilation holes, etc. of this unit.
@ Turn off after use
If the unit is left for a long time with the power on, this will not
only shorten its useful operation life, but may also cause other
unexpected trouble.
@ If water is spilled on the unit
Be extremely careful if water is spilled on the unit, because a fire
or serious electric shock might occur. Immediately disconnect
the power cord plug, and consult with your dealer.
M@ Place the unit where it will be well ventilated, and
away from direct sunlight
Place this unit at least 10 cm (4”) away from wall surfaces, etc.,
and away from direct sunlight. Be careful that curtains and
similar materials do not obstruct the ventilation holes.
M@ Keep the unit away from heaters, etc.
Heat can damage the external surfaces as well as internal cir-
cuits and components.
@ Avoid spray-type insecticides
Insecticides might cause cracks or “cloudiness” in the cabinet
and plastic parts of this unit. The gas used in such sprays might,
moreover, be ignited suddenly.
M@ Never use alcohol or paint thinner
These and similar chemicals should never be used, because
they may damage the finish.
M if trouble occurs
If, during operation, the sound is interrupted or indicators no
longer illuminate, or if abnormal odor or smoke is detected,
immediately disconnect the power cord plug, and contact your
dealer or an Authorized Service Center.
