only of the type described in the operating instructions or as marked on the unit.
2. Polarization—If the unit is equipped with a polarized AC power plug (a plug having one blade wider than the other), that plug will fit into the AC outlet only one way. This is a safety feature. If you are unable to insert the plug fully into the outlet, try reversing the plug. If the plug should still fail to fit, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the polarized plug.
3. Power Cord Protection—AC power supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them. Never take hold of the plug or cord if your hand is wet, and always grasp the plug body when connecting or disconnecting it.
4. Nonuse Periods—When the unit is not used, turn the power off. When left unused for a long period of time, the unit should be unplugged from the household AC outlet.
Installation
Environment
1. Outdoor Antenna Grounding—If an outside antenna is con nected to the receiver, be sure the antenna system is grounded so as to provide some protection against voltage surges and built-up static charges. Section 810 of the National Electrical Code, ANSl/NFPA No, 70-1990, provides information with respect to proper grounding of the mast and supporting structure, ground ing of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna-discharge unit, con nection to grounding electrodes, and requirements for the
grounding electrode. See figure below.
3. Heat—The unit should be situated away from heat sources such as radiators and the like. It also should not be placed in temperatures less than 5“C (41°F) or greater than 35“C (95“F).
4. Condensation—Moisture may form on the lens in the following conditions...
•immediately after a heater has been turned on.
•in a steamy or very humid room.
•when the unit is suddenly moved from a cold environment to a
warm one.
If moisture forms inside this unit, it may not operate properly. To
correct this problem, turn on the power and wait about one hour for the moisture to evaporate.
Placement
1.
Ventilation—The unit should be situated so that its location or position does not interfere with its proper ventilation. Allow
10 cm (4") clearance from the rear of the unit.

Concerning the remote control
Listening caution
Selecting fine audio equipment such as the unit you've just pur chased is only the start of your musical enjoyment. No%v it's time to consider how you can maximize the fun and excitement your equip ment offers. This manufacturer and the Electronic Industries Association's Consumer Electronics Group want you to get the most out of your equipment by playing it at a safe level. One that lets the sound come through loud and clear without annoying blaring or distortion—and, most importantly, without affecting your sensitive hearing.
We recommend you to avoid prolonged exposure to excessive noise.
Sound can be deceiving. Over time your hearing "comfort level" adapts to higher volumes of sound. So what sounds "normal" can actually be loud and harmful to your hearing. Guard against this by setting your equipment at a safe level BEFORE your hearing adapts. To establish a safe level:
•Start your volume control at a low setting.
•Slowly increase the sound until you can hear it comfortably and clearly, and without distortion.
Once you have established a comfortable sound level:
•Set the dial and leave it there.
Battery installation
• 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 con trol transmitter do not operate the unit even when the transmitter is held close to the front panel.

Taking a minute to do this now will help to prevent hearing damage or loss in the future. After all, we want you listening for a lifetime.
Correct method of use
• Do not place obstacles between the remote control signal sensor and remote control unit,
• Do not expose the remote control signal sensor to direct simlight 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.
To prevent damage
• Do not place heavy items.
• Do not disassemble or reconstruct.
• Do not spill water or other liquids.

For your reference
•You can take the front net off speakers,
• For your listening pleasure, keep your speakers from touching the system.
Caution Use the speakers only with the recommended system. Failure to do so may lead to damage to the amplifier and/or the speakers, and may result in the risk of fire. Consult a qualified service person if damage has occurred or if you
experience a sudden change in performance.
Placement of surround speakers
We recommend that surround speakers be placed on the side of or slightly behind the listener at ear level. However the position should be adjusted to your personal prefe rence, because the effect varies to some degree depending upon the type of music and the music source.
Optional surround speaker connections
Connecting the surround speakers produces a feeling of depth and movement of sound, and provides the listener with a feeling of presence like that of a movie theater.

Before moving your system to another location, be sure to remove all discs from the rack and turn off the system. The changer mechanism automatically locks when the system is turned off, to protect it against damage in transport. Therefore, always press POWER and make sure "GOOD BYE" appears on the display before you unplug the system. Failure to do so will expose the CDs and the system to the risk of severe damage.
