NOTES ON INSTALLATION.

Your NAD 510 should be placed on a firm, level surface. Avoid placing the unit in direct sunlight, near sources of heat and damp or in poorly ventilated positions.

The CD player comes with phono leads for connection to your amplifier or receiver. Switch the unit off before making any connections. Ensure that leads and connectors are not damaged in any way and all connectors are firmly pushed home.

If the unit is not going to be used for some time, disconnect the plug from the AC socket. Should water get into your NAD 510, shut off the power to the unit and remove the plug from the AC socket. Have the unit inspected by a qualified service technician before attempting to use it again.

Do not remove the cover, there are no user-serviceable parts inside.

Use a dry soft cloth to clean the unit and the CD Tray. If necessary, lightly dampened the cloth with soapy water. Do not use solutions containing benzol or other volatile agents.

As with most digital circuits, the processor inside your CD player may radiate a small amount of electrical 'noise' which could interfere with reception of very weak radio or TV signals. If this occurs, move the CD player away from the other devices or switch it off when viewing or listening to broadcasts.

WARNING TO UK USERS. If this apparatus is not fitted with a UK three-pin plug, do not attempt to insert the attached plug into a UK mains socket. Instead, cut the plug from the mains lead and attach a fused UK three-pin plug using the following safety advice on wiring.

IMPORTANT. The wires in this mains lead are coloured BLUE and BROWN;

BLUE:NEUTRAL BROWN:LIVE

The colours of these mains lead wires may not correspond with the coloured markings identifying the terminals in your plug. In this case the BROWN wire must be connected to the terminal which is marked

L(ive) or coloured RED. The BLUE wire must be connected to the terminal marked N(eutral) or coloured BLACK. No connection should be made to the terminal marked E or coloured green or green and yellow

Pressing Play again when the CD is already playing, will re-start playback from the beginning of the current track.

When the 510 is in Play mode, the Play mode indicator will be shown in the Display Panel. This will also show the current track number and position in the track in minutes and seconds.

5. PAUSE

Pressing PAUSE stops CD playback, without loosing the current position on the CD. Press PLAY to continue playback from that position on the CD.

Pressing PAUSE twice will cue up the beginning of the current track, whilst keeping the NAD 510 in Pause mode. Press PLAY to start playing the CD.

Both SCAN and SKIP can be used in the Pause mode to select other tracks, or another position on the current track before returning to play the CD.

When the 510 is in Pause mode, the Play mode indicator will flash and the Display Panel will show the current track number and position in the track in minutes and seconds.

6. STOP

The STOP button stops disc playing, cancels any Repeat mode, and returns the 510 to the start of the disk. In Stop mode, the Display Panel will show the total number of tracks and the total playing time of the disc.

7. TIME

The TIME button switches the Time Display through three different modes, showing either:

The time played of the current track, in minutes and seconds.

The playing time remaining for the current track, in minutes and seconds.

The total time played so far on the disc, in minutes and seconds.

The total playing time remaining on the CD, in minutes and seconds.

The 510 will normally display the current track number and position in the track in minutes, and seconds (the default display). Pressing the TIME button will cycle through the alternative display options and back to the default display.

8. DISPLAY PANEL

The Display Panel shows information about the NAD 510's operating modes and information about the CD currently loaded.

TRACK NUMBER. Displays the current track number being played or the track number that will be played when PLAY is pressed. When the disc is first loaded, Track Number shows the total number of tracks available on the disc.

TIME. Is used in conjunction with the TIME button. Normally in Play mode the Time Display shows the time played so far on the current track. The TIME button can switch this to display playing time remaining on the current track, time played so far on the disc, or playing time remaining on the disc current track. (See TIME Button)

TRACK LISTING. Displays a list of tracks available on the disc. As each track is played its number is blanked out on the Track Listing, giving a simple indication of how much of the disc has been played and how much remains. The display shows up to 20 numbered tracks. For CDs with more than 20 tracks, the 20+ indicator illuminates until all the tracks have been played.

The track Listing display does not operate in Random mode.

Pressing REPEAT a second time puts the player into Disc Repeat mode. This will continuously play the whole disc, returning to Track 1 each time the last track has been finished. In Disc Repeat, 'REPEAT' flashes in the Display Panel.

Pressing REPEAT a third time cancels the Repeat function and returns the NAD 510 to normal play from the current track. Pressing STOP also cancels the Repeat mode.

11. SKIP

The SKIP buttons will move the 510 on to the next track or back to the previous track on the disc.

In Stop mode, use Skip to select a particular track on the CD. Press SKIP Forward or SKIP reverse to select the required track number, which is shown in the Track Display. Pressing Play will then play the rest of the CD from that track number onwards.

In Play mode, pressing SKIP Forward jumps to the start of the next track. Pressing SKIP reverse jumps to the start of the previous track. After using Skip, the NAD 510 will then play all remaining tracks on the disc. If the disc is encoded with Index points within tracks, then Skip will jump to the start of the next or previous Index point.

Skip also functions in Random Mode, jumping to the start of the next or previous track in the Random Play sequence.

12. SCAN

The SCAN buttons fast forward or fast reverse through the tracks on the disc, giving an audible indication of the contents of the tracks.

To fast forward through a track in Play or Pause modes, press and hold down the SCAN Forward button and listen, or use the Track and Time displays, to find the required position on the track or disc. Release the SCAN button when the required position is located.

To move backwards through the track or the disk, press and hold down the SCAN Backwards button to find the required position.

Scan function stops when the beginning or the end of the disc is reached.

HANDLING AND LOOKING AFTER COMPACT DISCS

Compact discs need to be handled with care. Always hold the discs by the outer edges and avoid touching the playing (non-printed) surface of the disc. Remove the disc from the NAD 510 when it is not being played and store it in its CD case.

Minor scratches and finger marks will not affect the ability of the disc to play, although larger marks and damage may cause the disk to skip, repeat very short sections or stop altogether.

If this happens, inspect the disk for dirt or damage.

Clean CDs by wiping the playing surface with a soft dry cloth. Wipe from the centre of the disc outwards rather than radially. If the CD playing surface becomes dirty, lightly dampened the cloth with soapy water to remove any dirt and then wipe with a cloth lightly damped with water only. Do not use LP record cleaning solutions on your CDs.
