6.1 Disc Loading
To open the transport door press the player door button
or the handset open key. To load a disc place it on the
platter followed by the magnetic puck. Do not use a puck
from any other Naim CD player.
If the player is stopped the door will open automatically
when a hand is moved towards the proximity sensor
located in the player front panel display window.
To close the door press the player door button or the
handset open key. The door will also close if the player
play button or handset play key are pressed.
Note: If the door hits an obstruction the door indicator
will flash and the door will stop moving. Remove the
obstruction before attempting to open or close the door
again.
Note: If the door is left open for five minutes it will close
automatically to prevent inadvertent damage or dust
build-up within the player.
Note: If an HDCD
®
encoded compact disc is loaded the
CD 555 will automatically recognise and decode it. The
display will read HDCD for a few seconds after play is
pressed.
6.2 Player Maintenance
It is important for reliable operation of the CD 555 to ensure
that the surfaces of the transport platter and the underside
of the puck are free of dust or debris which can prevent
the disc from sitting properly and cause it to slip.
To clean the transport platter, take a piece of Blu-Tack and
lightly apply it to the top surface of the hub, picking up
any material attached to it. Brush the plastic outer edge
lightly with your finger or a soft brush to ensure that it is dust
and particle free. Similarly, clean the puck with Blu-Tack, to
remove debris from its underside.
Do not, under any circumstances, use any solvents or fluids
for the cleaning process.

6.3 Player Door Reset and Calibration
If at any time the player door fails to open or close
correctly, or the top panel door button flashes, the door
may need re-setting and calibrating. The procedures are
as follows.
It may only be necessary to carry out the Position
Calibration procedure.
6.3.1 Door Position Calibration
Switch the player off. Hold down the top panel door
button and switch the player on. The player display should
read
- - . Switch the player off and, after a short while,
back on again. If the door button flashes this indicates
that the Door
Reset and Motion Calibration procedures are
necessary. Carry out the following two procedures.
6.3.2 Door Reset
Note: Door Reset will also reset DIN/Phono Socket selection,
Display settings, RC5/RS232 settings and Control Mode
setting (see Section 19.2).
Switch the player off. Hold down the top panel stop button
and switch the player on. Switch the player off and carry
out the
Door Motion Calibration procedure.
6.3.3 Door Motion Calibration
With the door fully closed press and hold the top panel
door and play buttons and switch the player on.
The door will continually open and close and the level of
open/close gain adjustment will be displayed. Allow the
player to run until the values displayed for open and close
have settled to consistent values. The door should now
open and close consistently. Switch the player off and,
after a short while, back on again. The door should now
operate correctly.
