Suggestions for safety

Placement Power cord protection

Avoid placing the unit in areas of:

•direct sunlight

•high temperature

• high humidity

•excessive vibration

•uneven surfaces (Place the unit on a flat level surface.) Such conditions might damage the cabinet and/or other component parts and thereby shorten the unit s service life. To protect the unit against sound distortion and acoustical effects, please place the unit at least 15 cm away from wall surfaces etc.

Ventilation

Place the unit in a well-ventilated position at least 10 cm 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

• ft 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 if on a ship or other pface where DC is used.

• Avoid cuts, scratches or poor connection of the AC main cord, as this may result in fire or electric shock. 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

• Ensure that no foreign objects, such as needles, coins, screwdrivers etc., accidentally fail into the unit or through the ventilation holes. Otherwise, a serious electric shock or malfunction could occur.

• 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 immediately if this oc

curs.)

• Avoid spraying insecticides onto the unit as they contain flammable gases

which can be ignited.

• Insecticides, 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.

Service

• Never attempt to repair, disassemble or reconstruct the unit if there seems to be a probiem. A serious electric shock could result if you ignore this precautionary measure,

• If a problem occurs during operation (the sound is interrupted, indicators fail to

light up, 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.
