The Calendar display track listing will indicate the selected program.

NOTE: In the Program-entry mode, the SKIP CD-R AUDIO DISCS and

buttons have a “wrap-around” function: if you SKIP Back MAINTENANCE repeatedly from Track 01, the number counts down from the final track on the disc. This provides a convenient way to select high- numbered tracks.

INSTALLING AND REPLACING BATTERIES

The remote control requires two 1.5-volt AAA-size (i.e. UM-4 or IEC RO3) cells. Alkaline cells are recommended, to obtain maximum operating life. To open the battery compartment, place your fingertip in the recess on the rear of the remote control, push against the flexible edge of the battery cover and lift the cover upwards. Install fresh cells, orienting them as shown on the diagram within the compartment.

The coil springs should contact the (-) end of each cell. Push the battery compartment cover back and press gently until it latches. In some cases, corrosion or fingerprint oil on the battery contacts may cause poor operation. Remove both cells, rub the metal contacts at both ends of each cell with a clean cloth or a pencil eraser, and re-install the cells, being careful to orient them correctly.

Developed by Pacific Microsonics in the USA, HDCD® (High Definition Compatible Digital®) is a patented encode/decode process for delivering the full richness and detail of the recording.

HDCD® encoded CDs sound better because they are encoded with 20-bits of real musical information, as compared to 16-bits for all other CDs. HDCD® overcomes the limitation of the 16-bit CD format by using a sophisticated system to encode the additional four bits onto the CD while remaining completely compatible with the existing CD format.

The result is a larger dynamic range, a more focused 3-D soundstage, and natural vocal and musical timbre. An HDCD- encoded disc played on the HDCD-equipped NAD C541 CD player produces audibly superior clarity and depth. Enhanced performance will also be obtained from standard CDs.

The NAD C541 CD player will automatically identify an HDCD® encoded disc and activate its HDCD® decoder. The red indicator will light up when it’s playing an HDCD® encoded disc.

CD-R AUDIO DISCS

The C541 can play back CD-R audio discs that have been recorded on a computer or CD-recorder. It should be noted however that it will not play back CD-RW discs. The quality of CD-R audio discs varies widely which may affect playability.

Some factors that affect playability:

The quality of the disc itself. Generally speaking, CD-R blanks from well-renowned companies give better results than unbranded ones.

The quality of CD-recorder or computer CD re/writer. Some recorders and writers produce better results than others.

The CD-R was created with high-speed writing. In general, the quality of a CD-R is better when produced at a lower speed against a higher speed on the same recorder or re/writer.

MAINTENANCE

At periodic intervals, open the disc drawer and wipe with a damp cloth to remove any loose dust.

HANDLING COMPACT DISCS

Handle Compact Discs with care. The playback of a disc will not be impaired by small dust particles, a few light fingerprints, or slight scratches. But large scratches, or a thick layer of oily fingerprints, can pre-vent the player from tracking the disc. (Incidentally, although the tracking optical pickup “plays” the disc through its clear side, the actual data surface is embedded directly beneath the label, protected only by a very thin coating of lacquer. So a scratch that cuts through the label may damage the disc more than a similar scratch on the transparent “playing” surface. Thus you should treat both surfaces of the disc with care.) Severe scratches or fingerprints may cause the player to mis-track (skipping ahead, or repeating the same passage). Less severe damage may produce very brief bursts of high-frequency noise. The tracking and error-correction circuits of this NAD CD player are unusually sophisticated, providing secure tracking of flawed discs that are unplayable on some other players. Nevertheless, the discs should not be abused or handled carelessly. For best results, grasp the disc only by its edges.

CLEANING DISCS

Soiled discs may be cleaned by wiping with a soft cloth, either dry GB or moistened, with water. Do NOT use conventional LP record-

cleaning products (cleaning solutions, sprays, treated cloths, or anti-static preparations), nor any kind of chemical solvent (alcohol, benzene, et al). A severely soiled disc may be washed in a warm-water spray, possibly with a small amount of a mild kitchen detergent added, and then wiped dry with a clean, soft towel.

When cleaning the disc, use only RADIAL strokes (from centre to edge). Never use a circular wiping motion like that used for cleaning ordinary LP records, because in wiping the disc there is a risk of scratching it. A radial scratch will do the least harm because it affects only a small portion of each circular data track, which can be fully compensated by the player’ s error-correction circuits. But a circular scratch that follows a data track may damage such a long continuous segment of data that it cannot be corrected.
