PROTECTIVE SURFACE BEFORE COMMENCING
DISASSEMBLY.
! REFIT THE CD3.5 AND CD5 TRANSIT SCREWS BEFORE
BEGINNING.
! REFIT THE CDX AND CDX2 TRANSIT SCREWS AND
REMOVE THEM ONLY WHEN YOU ARE READY TO
REMOVE THE OUTER CASE. TAKE CARE THEN THAT THE
CD DRAWER DOES NOT FALL OPEN.
! DO NOT INVERT THE CDS2. WORK FROM UNDERNEATH
WHEN REMOVING THE CASE SCREWS.

Introduction
Enhancements
The PIC update brings each player up to the user interface
and play order programming feature set of CD players
manufactured after February 2003 (contact the Naim
Service Department for exact serial numbers).
User Interface
Front Panel Control
This multi-function mode provides an alternative front panel
interface in which fast forward, fast reverse and pause are
selected by pressing and holding next, previous and play
respectively.
To select multi function mode press and hold next while the
player is switched on. To select the standard control mode
press and hold previous while the player is switched on.
Static Pause
If a player is paused for more than 10 minutes it will enter
“static pause” mode in which the transport laser
deactivates and the disc stops spinning. The player can be
left in static pause indefinitely. Deselection of static pause
works in the normal way.
Display Defaults
Regardless of the selected display mode (track, time or off)
the display will default to time when fast forward or fast
reverse are operated or total programmed or disc time
when stopped.
Play Order Programming
Memory Limit
The play order program memory is now limited to 99 events
(program or delete) rather than the previous 20.
Preset Play Orders
Random and reverse play orders can now be selected from
the remote handset (from stop with no play order already in
place). Press prog followed by 1 for random play or prog
followed by 2 for reverse play.
Stop Function
Pressing and holding stop when a play order is
programmed will clear the play order but not reset the
display. A further press and hold of stop will reset the
display.
This PIC (programmable integrated circuit) update to the CD3.5, CDX, CDS2, CD5 and
CDX2 Compact Disc Players improves their ability to play “copy protected” compact
discs that do not comply with the Philips/Sony “Red Book” standard. The new PIC also
provides some user interface and play order programming enhancements. These are
described below. Updates should only be undertaken by authorised Naim distributors or
dealers.

Update Procedure
Disassembly
1. Ensure that the transit screws are fitted throughout the
update procedure. Invert the player on a clean work
surface covered with a protective material - a towel for
example
2. Identify the top cover fixings to be removed from the
diagram below. A diagram on the underside of the CD3.5
additionally illustrates one of two types of top cover to
chassis fixing that may be present on your player. Type
One fixing is four reusable plastic rivets. Type Two fixing is
four self tapping screws with plastic bushes.
For Type One fixing the male and female parts of each
plastic rivet must be prised apart and removed from the
cover. To do this, insert a flat bladed screwdriver or side-
cutters underneath the domed head of each rivet and
lever upwards removing the pin. Carry out the same
levering procedure to remove the female part of each
rivet. The rivets must be reused so do not discard them.
Put them safely to one side.
For Type Two fixing use a No. 2 Pozi-Drive screwdriver to
remove the four bushed self-tapping screws. Place the
screws and bushes safely to one side.
3. Using a No. 2 Pozi-Drive screwdriver remove the earth
screw and serrated washer located between the left hand
side top cover fixings. Place the screw and washer safely
to one side.
4. Hold the player at the front and back to retain the chassis,
top cover and CD drawer in place and turn it over.
5. With the player on the work surface facing away from you
slide the top cover towards you away from the chassis and
lift it clear. Put the top cover safely to one side.

PIC Replacement
6. Attach the earth strap around your left wrist (if right
handed) and connect its clip to any prominent internal
unpainted metallic feature of the chassis.
7. 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.
8. Use the PIC extraction tool, gripping the ends of the PIC,
to lift it from its socket. Discard the PIC.
9. 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
10. Slide the top panel back into place and, gripping the
player at the front and back to retain the chassis, top
cover and CD drawer in place, turn it over.
11. Align the top cover to chassis fixing holes and either refit
the plastic rivets by pressing the male section into the
female or insert and tighten the bushed self tapping
screws. Refit the earthing screw and washer.
12. Your CD3.5 has now been updated. Remove the transit
screws, re-connect it to the system and mains supply, and
switch on. The PIC update provides some enhanced
programming and user interface features. These are
described on Page 1.
