CHANGES IN COURSE OF PRODUCTION

•NEW SOFTWARE

- From production week 0152 onwards following new software versions have been implemented in the sets:

CDR80x:

Main µP 7414: V46
CDR module: MO2021, B0042 (MO stands for “Mozart Board”, B stands for “Basic Engine”)

CDR82x:

Main µP 7414: V34
CDR module: MO2021, B3201 (MO stands for “Mozart Board”, B stands for “Basic Engine”)

The upgrade of the CDR module addresses the following issues:

• Playback of Audio CD’s which do not comply with the Red Book standard

• New features in Service Testprogram

• Detection of corrupted mp3 files and proper handling of CRC errors

• Better track time prediction for VBR encoded mp3 files

• Improved CD-TEXT indexing

• Automatic Loader Detection during startup

• Several minor improvements
Software versions V34 (CDR82x) respectively V46 (CDR80x) of the main µP 7414 enable the extended Service Testprogram

which is already indicated in the Service Manual.
For updated flow charts of the Service Testprogram see attached sheets.

CDR820, CDR822

- From production week 0207 onwards the software of the Mozart Board has been upgraded to MO3001.

This upgrade addresses a major problem with the “Disc Recover Mode” of models CDR820, CDR822 and a few minor problems
valid for all sets.

Problem “Disc Recover Mode”:
After a power failure during recording, the set enters the “Disc Recover Mode” but it does never return from this mode. The
display shows “Disc Recover” even after disconnecting/reconnecting mains.
The faulty disc cannot be removed because the set does not react on any button (i.e. Open/Close).
The problem can be solved by a software upgrade of the Mozart Flash ROM to “MO3001”.
To remove the faulty disc from the tray proceed as follows:

1. Remove Top Cover

2. Connect mains → set will enter Recover Mode

3. Stop the disc manually until an error message is displayed

4. Press Open/Close

•

DISPLAY BOARD

The copper pattern has been changed to layout stage .7.

(The layout stage can be identified by the last digit of the 12-figure number, located at the upper left corner of the copper pattern)
Reason: To ensure a reliable startup with the flash-version of the µP over all tolerances, resistor 3497 has been added between

pin 9 of µP 7414 and ground.

The set does not automatically search for the place where a disc is inserted.
Only that disc will be played which is located on the compartment, which is just in PLAY position.
This will normally be

DISC 1

, except the carousel has been activated by the carousel test before.

It is therefore recommended to insert a CD-DA disc into compartment 1 before starting Service Testprogram.
