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.
