Appendix Looking after discs Storing discs Always keep discs in their cases and store them vertically in a place that's not subject to extreme temperatures, extreme humidity, or direct sunlight. Always read the precautions supplied with the discs. Handling discs • Always hold discs by the edge to protect them against fingerprints, scratches, and dirt. About specially shaped discs The DRX-730 cannot play discs with a special shape, such as heart and hexagonal-shaped discs. Such discs may cause a malfunction, so do not load them. Cleaning the pickup lens If dirt or dust collects on the DRX-730's pickup lens, the sound may jump or the picture may be disturbed. In such cases, contact your Yamaha dealer. Do not use commercially available pickup lens cleaners, as they may damage the lens. • Discs with fingerprints, scratches, or dirt may not play properly. In such cases, using a soft, dry cleaning cloth, wipe the disc from the center outward in straight lines. Do not wipe the disc in a circular motion, as this may damage it. Never use a dirty cleaning cloth. • For very dirty discs, try using a soft, damp cloth, and be sure to dry the disc afterward. Never use benzine, thinner, or other cleaning agents, such as those designed for cleaning vinyl records. • Do not load badly damaged, cracked, or warped discs into the DRX-730, as they may damage it. • Do not affix stickers or labels to discs, as they may cause the disc to warp and become unplayable. Rental discs often have stickers or labels attached. Make sure there's no glue jutting out from behind the label before playing such discs. • Do not load more than one disc in the DRX-730 at a time. • For more details on disc handling, refer to the precautions supplied with the disc. 60 En
