Suggestions for safety

Placement

Avoid piiicin^ the unit in ureas ot :

• 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 awav from wall surfaces etc.

Stacking

Never place heavy items on top of the unit

or the power cord.

Voltoge

• 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 con nection.

• A DC power source can not be used.

Be sure to check the power source care fully, especially if on a ship or other place

where DC is used.

Power cord protection

• 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 puli on the cord when you are disconnecting the power, as this could cause iin electric shock. Grasp the plug

firmly when you disconnect the power supply.

• Never touch the plug with w^et hands or

a serious electric shtKk could result.

Foreign moteriols SSîi

• Ensure that no foreign objects, such as needles, coins, screwdrivers etc., acciden tally fall into the unit or through the ven tilation holes. Otherwise, a serious electric shock or malfunction could occur.

• Be extremely careful about spilling wa ter 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 tKcurs.)

'iv. --t:m Iff • ,Vi m.iiri 'K (fii w-15cm w ±

• 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 dean the unit as they can cause flak ing or cloudiness to the cabinet finish.

Service

• fi' ni 411 l’If ) n ff-j ff.'i m AC -t fiâi ' i

• Never attempt to repair, disassemble or reconstruct the unit if there seems to be

• friti'imDC'.iiï));;-

a problem. 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. Other wise the operation life could be short ened.

Use of batteries

Do not mix old and new batteries, or batteries of different types {manganese and alkaline, etc,). Never subject batteries to excessive heat or flame; do not attempt to disassemble them; and be sure they are not short-circuited. If the remote control is not to be used for a long period of time, remove the batteries and store them in a cool, dark place.

Do not attempt to recharge alkaline or manganese batteries.

Do not use rechargeable type batteries.

Battery life

The battery life is about one year.

The batteries should be replaced if commands from the remote control

transmitter do not operate the unit even when the transmitter is held

close to the front panel.

Correct method of use

Operations notes

Do not place obstacles between the remote control signal sensor and remote control unit. Do not expose the remote control signal sensor to direct sunlight or to the bright light of an invertor fluorescent light. Take care to keep the remote control signal sensor and end of the remote control unit free from dust. If this system is installed in a rack with glass doors, the glass doors' thickness or color might make it necessary to use the remote control a shorter distance from the system.

Metal net

iuill-e 4¡Í,iaaáu

To prevent damage

• Never place heavy items on top of the unit.

• Do not disassemble or reconstruct the unit.

• Do not spill water or other liquids into the unit.

Tape the antenna to a wall or column, in a position where

radio signals are received with the least amount of interference

For best reception sound quality:

An FM outdoor antenna is recommended, {See page 10.)

AM loop antenna

After attaching the antenna, turn on the system and tune in a broadcast station. Then, turn the antenna to the angle of best

reception and least interference.

0 Connect the right (R) and left (L) speaker cords

(pin type).

0 Connect the right (R) and left (L) speaker cables.
