INFORMATION :During transportation the pin on the Crank (pos 96) might jump out of
the groove on the Tray (pos 108).
From production wk9835 onwards, the Tray and Crank have been
modified.The groove on the tray is now deeper and likewise the pin
on the Crank is 3mm longer.
Due to this change the new Crank does not fit into the old Tray
anymore.But it is still possible to use the old Crank on the new Tray.
The service code numbers for the Cranks are as follows:
4822 535 40105 Old Crank
4822 402 11241 New Crank
Service Newsletter 1999 – Audio Systems 1/10
Page 2
The new Tray can be recognized by its 10mm deep groove.
Because of limited stock of old Cranks, new Cranks have to be
reworked for sets with an old Tray. This is done by cutting the pin by
3mm with a sharp NT-cutter (give it a clean cut & do not deform its
circular cross-section) as shown below.

01.03 TYPENUMBER(S): ALL CDR TYPENUMBERS
INFORMATION: The user problems in this publication are separated into the following
categories:
1. Playback behaviour
2. Recording behaviour
3. Operating behaviour
1. PLAYBACK
1.1. Display indicates: No disc
◆ Indeed no disc inserted
◆ Inserted disc is not recognised by Loader CDR mechanism
(defective disc or damaged disc)
◆ Does the set work properly with another CDDA disc (pre-recorded Audio disc)?
❏ If Yes then disc is indeed defective
❏ If No then check the functioning of the set.
◆ Disc is not positioned correctly on tray at inserting and therefore not recognised by
Loader CDR mechanism, reposition disc on tray.
1.2. CD-RW disc is not recognised
◆ Is it a CD-RW Digital Audio disc?
❏ If Yes and if the set is working properly on other recording discs, this par ticular disc
should be “DC-Erased” (Power off, ERASE + RECORD simultaneously and switch
Power on) This operation takes about 37 minutes and returns that CD-RW disc to its
virginal status again.
2. RECORDING
2.1. Analogue input signal recorded is distor ted at Playback.
◆ When recording analogue signals via tape or cassetterecording customer is used to
overpower the input signal.This brings more dynamic in recorded signal.
◆ For digital recording there is enough dynamic space between 0 dB till about -95 dB, so
overpowering is not necessary, the opposite is true; by digitalizing an overpowered
signal ‘mutes’ are converted, resulting in the distorted stored signal
2.2. Digital connected, tracks are not incremented
◆ Is Auto track increment function switched on. If not switch on Automatic track increment
◆ Digital source is using another digital output than IEC958 format (consumer part). This
is due to the transmitted subcode information which contains other data than the subcode information in the CD-format.To have the advantage of digital recording, the
Digital Audio Data is recorded without any problem. However the track-increment bit is
not transferred.
Service Newsletter 1999 – Audio Systems3/10
Page 4
2.3. Disc full after some or a few tracks.
Disc full message can be the result after a misrecording.
◆ Misrecordings due to customer actions are:
• bumps against recorder: prevent bumps onto the set during recording process.
• dust on disc: prevent dust particles on disc
• scratches on disc: prevent scratches on disc
• set is suddenly powered off: prevent switching off!!
◆ Misrecording due to improper working of CD Recording Module:
• In case the error occurs always at the same time indication then Optical Pick-up Unit
is not exactly following the Pregroove track on that position: replace CD-Recording
Module (CDR765, CDR760, CDR560, CDR538; 4822 691 10737) or the CDRLoader
module part CDR870, CDR880: 4822 218 12745)
◆ In case a CD-R disc is used, each misrecording will automatically activate the finalizing
process of the recorder, because after a misrecording it is not possible to add further
recordings onto that CD-R disc.To have all proper recordings stored, the TOC of the
disc is filled.
◆ In case a CD-RW disc is used, the last recorded track will be overwritten when making
further new recordings. Here the disc is not finalized automatically, but PMA (program
memory area) is filled with the number of proper recorded tracks.
2.4. Analog input is so low that tracknumber is incremented and recording stops.
◆ If analog input signal starts very low (-35 dB) and automatic track increment is switched
on then track nummer x will be followed by next number (x+1) after 4 seconds. If this
low signal still continues the recording will be switched off after some seconds.
◆ By applying Manually track increment this signal can be recorded.
◆ Automatic switch off has been modified by adapting µP software program in CDR765,
CDR760, CDR560, CDR538.
2.5. Loud noise on CD-RW disc
◆ CD-RW erasings are only done in PMA.The or iginal signal will be overwritten later on. It
might occur that the overwriting does not start at exactly the beginning of the frame of
the track to be overwritten. In case overwritten signal consisted out of loud signal, then
this short remaining signal can give this suddenly loud noise.
◆ For this phenomenon no better solution is possible.
3. OPERATING
3.1. Finalizing takes approx. 5 minutes
◆ Normally finalizing takes approx. 2 minutes.
◆ Due to the fact that finalizing is done at speed N=2.
◆ In case something goes wrong finalizing is automatically switched over to speed N=1
and procedure will restart. (4 minutes)
◆ Now in IFU is stated:“ Finalizing takes at least 2 minutes”
3.2. CD-sync activated and in first track 1 second deviation upon original disc.
◆ Via CD-sync, the recorder is brought in record standby position at the last recorded
position on the program area.
◆ When CD-player is started the digital signal is brought to digital in.When this signal
arrives immediately the linking procedure starts. After reading the last recorded 14
frames the recording of the digital input signal starts. As no buffer is used the first
frames are not stored. (Max. about 400 msec. are lost)
Service Newsletter 1999 – Audio Systems4/10
Page 5
3.3. How to erase one track between other tracks on CD-RW disc?
◆ It is not possible to erase tracks between other tracks.Only the last recorded track can
be erased. In case of an erasure between tracks make first a copy of the to be safed
tracks to another disc and then erase track after track to the desired position and add
stored recording again.
3.4. Can a copy of another copy be made?
◆ For Philips Digital Audio CDR recorders SCMS protocol is valid
◆ This applies even to devices without a digital output
◆ SCMS allows any number of digital copies of original sound carriers, but prevents
further digital copies of this created master.
◆ copies of this created master can only be made via D/A -> A/D conversion.
◆ According to audio interface standard IEC958, via channel status bit (timeslot30), the
channel status word consists out of 384 bits per blok,each bit repeated twice so 192
channel status bits per blok are available. In channel status word every digital source is
identified by an 8-bit “category code” Category code is formed by bit 8-15 of the channel
status word.
◆ bit 15 of timeslot 30 or the last bit of the category code is called L-bit. This bit
indicates an original source, commercially released pre-recorded software (L=“1”) or a
personal recording or “home copy” (L=“0”) No indication.
◆ Control code gives the transmission mode and the copy protection status of the signal
that is transmitted.
◆ the transmission mode is given by the bits 0 and 1 of the channel status word.
◆ Bit 2 contains the copy status (C-bit).
◆ C-bit = “0” for protected and “1”for unprotected material ”alt” for “home copy of copyright
protected original”
◆ On recorded disc the copy bit defines the copy status:
◆ Q-control bit 1 (copy bit) copy protection status:
◆ Q-control bit 1 = “1” for protected,
◆ Q-control bit 1 = “0” for unprotected material
◆ Q-control bit 1 = alternating between “0” and “1” (alt) for “home copy of copyright
protected original”
On recorded disc the copy bit defines the copy status summarised in one table:
3.5. Can CD-i disc be copied to Audio CDRrecorder?
◆ Digitally connected only the CD DA tracks on that disc
◆ CD-i disc complete is not possible, only CD DA discs.
◆ Only via analogue connection the Audio signal can be copied
3.6. Can VCD disc be copied to Audio CDRrecorder?
◆ Digitally connected only the CD DA tracks on that disc
◆ VCD disc complete is not possible, only CD DA discs
◆ Only via analogue connection the Audio signal can be copied

3.7. Can CD-ROM disc be copied to Audio CDRrecorder?
◆ Digitally connected only the CD DA tracks on that disc.
◆ CD-ROM disc complete is not possible, only CD DA discs
◆ Only via analogue connection the Audio signal can be copied
3.8. Can more than one digital connection be made from one source?
◆ Only one digital connection per output can be made. Using more digital recorders which
are digitally connected via Input and Output sockets behind each other is very limited
because the IEC958 clockbit will deviate too much, resulting in a non proper recording.
3.9. Display indicates: No Audio
◆ Professional Recording Disc has been inserted in loader
◆ use Digital Audio CD-R or Digital Audio CD-RW discs.
01.04 TYPENUMBER(S): CDR538, CDR560, CDR760
INFORMATION: To solve “No copy“ problem in FW538 systems when recording
digitally new software version V2.4.has been introduced.
With SW V2.4 the unit will go into Record Standby after recording
instead of Stop.If no further audio signals are presented for recording
within 1 minute after going into Standby mode, the unit will go to
Stop.This solves the problem of recording with CD Changer systems.
The new SW V2.4 has to be implemented for IC 7322 on the CDR
Main Board and is available under service codenumber
4822 900 11306.
REMARKS: SW V2.4 has been introduced in production:
for CDR538/00S, CDR560/00S and CDR560/06S in week 9849
marked with AH-no.03.
for CDR560/11S in week 9902 with AH-no. 02.
for CDR560/17 in week 9902 with AH-no. 01.

SYMPTOM:
Shock sensitivity CD-Player part, audio-mutes on recorded CD after
dubbing
CURE: The CD-Player module is very sensitive to shocks.Also dur ing
dubbing of an audio-CD, mutes can be heard on the recorded CD.
These mutes are mostly located in track 1.Both of these problems
can be solved by a software upgrade to V1.6 for IC 7220 on the CD
Main Board. Service code number reads 4822 900 11309.
The shock sensitivity problem had already been addressed in item
08.06 of issue AS98.08 (98-10-30) of the Service Newsletter.The
cure for the above problem(s), as mentioned in that Service
Newsletter, needs to be changed as follows:
Upgrading IC 7220 on the CD Main Board to SW V1.6, solves the
problems of shock sensitivity and audio mutes, regardless of the
suspension grommets used in the CD-Player module.
REMARKS: Together with the new software V1.6, the original black suspension
grommets will be reintroduced into production from week 9903
onwards.
The CD-Loader unit with modified software has been marked VN03.
The set with built-in modified software has been marked VN04.
01.09 TYPENUMBER(S): CDR870
INFORMATION: A printing error has occurred on the front page of the CDR870
Service Information Issue A98-250. The service codenumber of part

after the source has stopped or after disconnection of the source
(Autostop).
REMARKS: SW V1.7 will be introduced from week 9904 onwards with AH-no.02
for CDR880/00, CDR880/00S, CDR880/06S and CDR880/17.
INFORMATION: Replacement of CDM12.1 for 7-Disc Changer
Production of CDM12.1 will stop.For service pur pose CDM12.1
(4822 691 30278) will be replaced by service kit VAM1201
(4822 310 11263) when stock depletes.
For the above mentioned sets with 7-Disc Changer the new
VAM1201 does not fit.
As an alternative, the CDM12.1 can be replaced by CDM12.1/T
(4822 691 30343) without any further modifications.
When CD tray was activated to open, the tray would move out and
immediately go in again or stop at half way.
When the CD tray is in motion the inside arm of the switch bracket
(pos 123) hits the micro switch earlier than the main lever.
CURE: The problem can be solved by cutting a section of the inside arm of
the switch bracket as indicated below:
REMARKS: The phenomenon can be simulated by tilting the set at either side for
CURE: The problem is caused by defective capacitors at positions 2617 and
2618 on the AF3-board.
It is resolved by replacing them with new ones.
