ISSUE 1

02/2003

Introduction

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.

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 not

CDS2) 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.

Case Disassembly

CD3.5, CDX, CDS2, CD5

1. Identify the appropriate case fittings from the diagrams

opposite. Remove the outer case or top panel (CD5) and

place the player chassis facing forwards on a clean work

surface.

2. Attach the earth strap around your left wrist (if right

handed) and connect its clip to any unpainted metallic

feature of the chassis.

3. Use the diagrams on the back page to identify the PIC

Socket and PIC. Note the PIC orientation in the socket -

there is a semicircular indent at one end. The replacement

PIC must be inserted with the same orientation.

4. Use the PIC extraction tool, gripping the ends of the PIC,

to lift it from its socket. Discard the PIC.

5. 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.

6. Disconnect the earth strap and replace the player outer

case or top panel.

7. The player has now been updated. Reconnect it to the

system and power supply, and switch on.

Procedure

CDX2

1. Identify the appropriate screws from the diagrams

opposite. Remove the outer case and place the player

chassis facing forwards on a clean work surface.

2. Attach the earth strap around your left wrist (if right

handed) and connect its clip to any unpainted metallic

feature of the chassis.

3. Use the diagrams on the back page to identify the PIC

Socket and PIC. Note the PIC orientation in the socket.

There is a chamfer with a dot located on one side of the

PIC. The replacement PIC must be inserted with the same

orientation.

4. You will notice two recesses on opposite corners of the

PIC Socket. Place the small barbed end of the PIC

extraction tool at a slight angle into one of the recesses in

the corner of the PIC Socket. Lever the PIC partially out of

its socket. Place the barbed end similarly into the opposite

recess and lever the PIC fully out of the socket.

5. Place the replacement PIC squarely into the socket.

ENSURE CORRECT ORIENTATION. Apply mild thumb

pressure to push the PIC into the socket so that it is flush

to the top of the socket.

6. Disconnect the earth strap and replace the player outer

case.

7. The player has now been updated. Reconnect it to the

system and power supply, and switch on.
