6. CD555 In Use

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
CD555 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 CD555 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.
Note: 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 16.2).
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.
