Placement
Avoid placing the unit in areas of:
e direct sunlight
*high temperature
@ high humidity
e excessive vibration
uneven surfaces (Place the unit on a flat level surface.)
Such conditions might damage the cabinet and/or other compo-
nent parts and thereby shorten the unit's service life.
Ventilation
¢ Place the unit in a well ventilated position at least 10 cms away
from wall surfaces etc.
Ensure that curtains and similar materials do not obstruct the
ventilation holes.
Stacking
Never place heavy items on top of the unit or the power cord.
Voltage
e It is very dangerous to use an AC power source of high voltage
such as for an air conditioner.
A fire might be caused by such a connection.
¢ A DC power source can not be used.
Be sure to check the power source carefully, especially on a
ship or other place where DC is used.
Power cord protection
® Avoid cuts, scratches or poor connection of the AC mains cord,
as this may result in fire or electric shock hazard.
Excessive bending, pulling or slicing of the cord should also be
avoided.
© Do not pull on the cord when you are disconnecting the power,
as this could cause an electric shock. Grasp the plug firmly
when you disconnect the power supply.
® Never touch the plug with wet hands or a serious electric shock
could result.
Foreign materials
eEnsure that no foreign objects, such as needies, coins,
screwdrivers etc., accidentally fall into the unit or through the
ventilation holes.
Otherwise, a serious electric shock or malfunction could occur.
e Be extremely careful about spilling water or liquid on/into the
unit, as a fire or electric shock could occur.
(Disconnect the power plug and contact your dealer immediate-
ly if this occurs.) :
e Avoid spraying insecticides onto the unit as they contain flam-
mable gases which can be ignited.
eln secticides, alcohol, paint thinner and similar chemicals
should never be used to clean the unit as they can cause flaking
or cloudiness to the cabinet finish.
Maintenance
Clean the cabinet, panei and controls with a soft cloth lightly
moistened with mild detergent solution.
Do not use any type of abrasive pad, scouring powder or solvent
such as alcohol or benzine.
Service
© Never attempt to repair, disassemble or reconstruct the unit if
there seems to be a problem.
A serious electric shock could result if you ignore this precau-
tionary measure.
¢ if a problem occurs during operation (the sound is interrupted,
indicators fail to illuminate, smoke is detected, etc) contact
your dealer or Authorized Service Center immediately.
¢ Disconnect the power supply if the unit will not be used for a
long time. Otherwise the operation life could be shortened.
CAUTION
Do not place a tape deck or CD player on top of this unit.
Heat radiated from the top of this unit may cause damage to
the tape or CD software.
