Before use

Placement precautions

• Do not install this unit in a location that could become hot. This includes places that are exposed to direct sunlight or near a radiator, heater, stove or other heating equipment. Moreover, do not place it on top of an amplifier or other equipment that generates heat. Doing so could cause discoloration, deformation or malfunction.
• When installing this unit, leave a little space (at least 3 cm or 1") between it and walls and other devices in order to allow good heat dissipation.
  If you put it in a rack, for example, leave at least 5 cm (2") open above it and at least 10 cm (4") open behind it.
  Failure to provide these gaps could cause heat to build up inside and result in fire.

Note about pinpoint feet

High-precision metal pinpoint feet are attached firmly to the bottom plate of this unit.
The stands for these feet are loose, but when the unit is placed in position, it is supported by these pinpoint feet, which will effectively disperse vibrations.

• The included felt pads are intended to protect the surface where the unit is placed. Apply them to the bottoms of the foot-stands.

Maintenance

Wipe dirt from the top cover and other panel surfaces using a soft cloth that has been slightly dampened with a diluted neutral cleanser.
Do not wipe with chemical cleaning cloths, thinner or other chemical agents. Doing so could damage the surface.
For your safety, disconnect the power cord from the outlet before cleaning.

Using the remote control

Precautions for use

Misuse of batteries could cause them to rupture or leak, which might result in fire, injury or the staining of nearby materials. Please carefully read and observe the precautions.

• When using the remote control, point it toward the remote control signal receiver on the main unit from a distance of 5 m (16 ft) or less. Do not place obstructions between the main unit and the remote control.
• The remote control might not work if the remote control signal receiver on the unit is exposed to direct sunlight or bright light. If this occurs, try moving the unit.
• Beware that use of this remote control could cause the unintentional operation of other devices that can be controlled by infrared rays.

Installing batteries

Remove the cover from the back of the remote control and insert two AAA batteries with their / oriented as shown in the case. Replace the cover.

When to replace batteries

If the distance required between the remote and the main unit decreases or if the unit stops responding to the remote buttons, replace both batteries with new ones.
Dispose of the used batteries according to the instructions on them or requirements set by your local municipality.

Discs

The following marks appear on disc labels and disc cases. This unit can play discs that have these marks without using an adapter. This unit cannot play discs that do not have these marks.

Types of discs that can be played on this unit and their marks
CDs with the "COMPACT disc DIGITAL AUDIO" logo (12 cm, 8 cm)

• This logo appears on disc labels and packages.

If you try to play any other type of disc with this unit, loud noises that could damage speakers or harm hearing might occur. Never try to play any type of disc other than those shown above.

• This unit cannot play DVD video, DVD audio, video CD, DVD-ROM and CD-ROM discs, for example.
• This unit might not be able to properly play Dual Discs, Copy Control CDs or other special CDs that do not conform to the Red Book CD standard. Operation and sound quality cannot be guaranteed when special discs are used in this unit. If playback of a special disc should cause trouble, contact the seller of the disc.

CD-R/CD-RW discs
This unit can play CD-R/CD-RW discs that are in audio CD format.

• Be sure to finalize discs created by CD recorders.

Depending on the quality of the disc and the condition of the recording, playback might not be possible. For details, see the operation manual for the device you are using.

Handling discs

• Load discs with their labeled sides up.
  (CDs only have one playable side.)
• To remove a disc from its case, always press down on the center of the case first and then hold the disc by its edges.
  
• Be careful when handling discs. If the side that contains the data (unlabeled side) is scratched, smudged with fingerprints or otherwise dirty or marred, errors could occur during playback.
• If the side of the disc that has the data encoded on it (unlabeled side) becomes dirty with fingerprints or dust, use a soft cloth to wipe the surface from the center directly toward the edge.
  Always clean discs before storing them. Leaving a disc in an unclean state might degrade its sound quality.
  
• Never use record cleaners, antistatic treatments, thinners or similar chemicals to clean discs. Such chemicals could harm the surface of the disc.
• Do not leave discs in places that are exposed to direct sunlight or that are very humid or hot.
• When writing something on the label side of a disc, use a felt tip permanent marker. The use of a ballpoint pen or other pen with a hard tip could damage the disc, making it unplayable.
• After you finish playing a disc, always put it back into its case for storage. Failure to do so could result in warping and scratches.
• Do not apply labels or other materials to discs. Do not use a disc that has sticky residue left on its surface after removing tape or a sticker, for example. If such a disc is loaded, it might become stuck in the unit or damage the unit.
• Never use commercially-available CD stabilizers. Doing so could make the disc unplayable or damage the unit.
• Do not use cracked discs because they could damage the unit.
• Never use discs with irregular shapes, including heart-shaped and octagonal discs, because they could damage the unit.
  
• Do not use printable discs, which allow printing on the label side. Since the surface of such a disc has been specially treated, if loaded, it might become stuck in the unit or damage the unit.

If you have any questions about how to handle a CD-R or CD-RW disc, contact the manufacturer of the disc directly.

Connecting speakers

Notes about speaker cables

• Use commercially-available speaker cables to connect the speakers.
• Use the shortest speaker cables possible. The longer the cable, the greater the resistance value and the more that damping performance is reduced. Moreover, length also increases impedance and capacitance, degrading the sound quality of high frequencies.
• Use left and right speaker cables that have the same length.

How to connect speaker cables

Use commercially-available speaker cables to connect the terminal of the unit to the terminal of the speaker and the terminal of the unit to the terminal of the speaker.

• Use speakers with at least 4Ω impedance.
• If the exposed tip of the core wire of a speaker cable contacts another cord or terminal, a short could occur. Never allow a speaker cable to short.
• Do not connect more than one amplifier to a speaker.
• Do not bundle speaker cables with power cords. Doing so could cause noise.

The power plug should always be disconnected when connecting speaker cables.

When using bare wires
Loosen the cap and insert the core wire into the hole in the terminal. Then, tighten the cap.

When using spade lugs
Loosen the cap and insert the lug between the cap and base of the terminal. Then, tighten the cap.

• When using a spade lug to connect, use one with an inside diameter of at least 8 mm (3/8").

When using banana plugs
With the cap tightened, insert the plug into the opening in the end of the terminal.

• Carefully read the instructions for the banana plugs that you are using.

Notice about the European model
In accordance with European safety regulations, connecting banana plugs to speaker terminals is not allowed on European models.
The holes into which banana plugs could be inserted have been covered with black caps.
Connect speakers using bare wires or spade lugs.
If a black cap should become separated from its terminal, return it to its original position.
