Update Procedure
Disassembly
Note: Take care not to subject the player to sudden
movement or shocks that might put undue load on the
printed circuit board and transport suspension systems.
The player must not be inverted.
1. Place the player feet down on a flat, clean work surface
with the back panel facing you. Identify the sub panel
located at the left hand end of the rear panel (behind the
CD Transport area). Using a No. 1 Pozi-Drive screwdriver,
unscrew the two screws holding the sub panel in place and
remove it.
2. The four foot/case retaining screws and one earthing bolt
on the underside of the player must now be removed. This
must be done however WITHOUT INVERTING THE PLAYER.
Rotate the player in stages so that each foot screw and
the earthing screw become accessible over the edge of
the work surface and, working from underneath, remove
each screw using a No. 2 Pozi-Drive screwdriver. These
screws/bolt are the only ones on the underside of the
player. There is no danger of removing an incorrect screw.
3. Place the player on the work surface with the front panel
facing you. Reaching behind the player, slowly push on the
rear panel so that the chassis begins to slide forward and
out of the external case. When the chassis is
approximately halfway out, detach the cable connecting
the lid sensor mechanism from its push-fit connector on
the main printed circuit board. Continue to slide the
chassis out of the case until it is completely clear.

4. Attach the earth strap around your left wrist (if right
handed) and connect its clip to any prominent internal
unpainted metallic feature of the CDS2 chassis.
5. Use the diagram below to identify the PIC Socket and PIC.
Note the PIC orientation in the socket. There is a
semicircular indent and a dot located at one end of the
PIC. The replacement PIC must be inserted with the same
orientation.
6. Use the PIC extraction tool, gripping the ends of the PIC,
to lift it from its socket. Discard the PIC.
7. Place the replacement PIC squarely into the socket so that
its “legs” line up with the individual sockets. ENSURE
CORRECT PIC ORIENTATION. Apply mild thumb pressure to
push the PIC into the socket so that it is fully home.
Remove the earth strap.
Reassembly
8. Place the player’s external case behind the chassis, lift
the chassis slightly and slowly slide it back into the case.
Re-connect the lid sensor cable to the board mounted
connector when the chassis is around halfway back into
the case. The chassis is positioned correctly when the
case overhang at the front and rear is equal.
9. Without inverting the player, replace the four foot/case
screws, and the single earth bolt and crinkle washer.
Replace the rear sub-panel.
10. Your CDS2 has now been updated. Re-connect it to the
system and power supply, and switch on. The PIC update
provides some enhanced programming and user interface
features. These are described on Page 1.
