PRECAUTIONS Product Cleaning Use a soft dry cloth for periodic cleaning of the product. For more severe stains, please dampen the cloth with water only. Anything else has the chance of dissolving the paint or damaging the plastic. Temperature Do not operate your unit in ambient temperature above +60°C (+140°F) or below -10°C (+14°F). Moisture Condensation You may notice the disc playback sound wavering due to condensation. If this happens, remove the disc from the player and wait about an hour for the moisture to evaporate. Damaged Disc Do not attempt to play cracked, warped, or damaged discs. Playing a bad disc could severely damage the playback mechanism. Maintenance If you have problems, do not attempt to repair the unit yourself. Return it to your Alpine dealer or the nearest Alpine Service Station for servicing. New Discs When a newly purchased disc is inserted into the changer magazine, the disc may fail to play after initial loading. This is caused by small bumps around the center hole and outside of the disc, which prevent stable loading into the correct position. To remove the bumps, rub the inside edge of the hole and outside edge of the disc with a ball-point pen or other such instrument, then insert the disc again. • The mechanism automatically prevents this type of disc from playing as a protective measure. This is not an indication of faulty operation. Center Hole Center Hole New Disc Bumps Outside (Bumps) Irregular Shaped Discs Be sure to use round shaped discs only for this unit and never use any special shaped discs. Use of special shaped discs may cause damage to the mechanism. Installation Location Make sure the DHA-S690 will not be installed in a location subjected to: • Direct sun and heat • High humidity and water • Excessive dust • Excessive vibrations Correct Handling Do not drop the disc while handling. Hold the disc so you will not leave fingerprints on the surface. Do not affix tape, paper, or gummed labels to the disc. Do not write on the disc. CORRECT INCORRECT CORRECT Disc Cleaning Fingerprints, dust, or soil on the surface of the disc could cause the DVD changer to skip. For routine cleaning, wipe the playing surface with a clean, soft cloth from the center of the disc to the outer edge. If the surface is heavily soiled, dampen a clean, soft cloth in a solution of mild neutral detergent before cleaning the disc. Disc Accessories There are various accessories available on the market for protecting the disc surface and improving sound quality. However, most of them will influence the thickness and/or diameter of the disc. Using such accessories can cause operational problems. We recommend not using these accessories on discs played in Alpine DVD changers. Transparent Sheet Disc Stabilizer 4-EN
