Introduction / Technical Specifications

1. Introduction / Technical Specifications
1.1 General
CD Recording Mozart Module is a module for playback of
Audio/Data CD’s (incl. CD R/W) and recording on Audio CDR and CD-R/W Disc consisting of:
• CD (Recording) Drive Mechanism
• Tray Loading Mechanism
• Front-end Board inclusive CD -Servo control Software
• Backend Board containing Application software
• Metal Encasing (for EMC Screening and mechanical
fixation)
Not included is the User Interface that has to be handled by
the Set front application. This user interface controls
functions that are set independently like: display and key
handling.
Note: The EMC screening is not mounted in some
applications.
The CD (Recording) Drive Mechanism, Tray Loading
Mechanism and Front-end Board part of the module can
have 2 different executions. One is called FREYA the other
RACOON. As information and repair activity about
RACOON is not defined yet, this part is not included in this
Service Manual.
Notice that both Mechanisms can not be interchanged, so
RACOON has to be replaced by RACOON, FREYA by
FREYA. As both parts can only be repaired with the help of
CDR-ComPair, the ComPair tool will contain the instructions
for both mechanisms.

Safety and Maintenance Instructions Warnings and Notes
GB 4 CDR Mozart2.
2. Safety and Maintenance Instructions Warnings and Notes
SHOCK, FIRE HAZARD SERVICE TEST:
CAUTION: After servicing this appliance and prior to returning to customer, measure the resistance between
either primary AC cord connector pins (with unit NOT connected to AC mains and its Power switch ON), and the
face or Front Panel of product and controls and chassis bottom,
Any resistance measurement less than 1 Megohms should cause unit to be repaired or corrected before AC
power is applied, and verified before return to user/customer.
Ref.UL Standard NO.1492.
NOTE ON SAFETY:
Symbol
: Fire or electrical shock hazard. Only original parts should be used to replace any part with symbol
Any other component substitution(other than original type), may increase risk or fire or electrical shock hazard.
F
ATTENTION
Tous les IC et beaucoup d'autres semiconducteurs sont sensibles aux décharges
statiques (ESD).
Leur longévité pourrait être considérablement
écourtée par le fait qu'aucune précaution
n'est prise a leur manipulation.
Lors de réparations, s'assurer de bien être
relié au même potentiel que la masse de
l'appareil et enfiler le bracelet serti d'une
résistance de sécurité.
Veiller a ce que les composants ainsi que les
outils que l'on utilise soient également a ce
potentiel.
D
WARNUNG
Alle IC und viele andere Halbleiter sind
empfindlich gegen elektrostatische
Entladungen (ESD).
Unsorgfältige Behandlung bei der Reparatur
kann die Lebensdauer drastisch vermindern.
Sorgen sie dafür, das Sie im Reparaturfall
über ein Pulsarmband mit Widerstand mit
dem Massepotential des Gerätes verbunden
sind.
Halten Sie Bauteile und Hilfsmittel ebenfalls
auf diesem Potential.
NL
WAARSCHUWING
Alle IC's en vele andere halfgeleiders zijn
gevoelig voor elektrostatische ontladingen
(ESD).
Onzorgvuldig behandelen tijdens reparatie
kan de levensduur drastisch doen
verminderen.
Zorg ervoor dat u tijdens reparatie via een
polsband met weerstand verbonden bent met
hetzelfde potentiaal als de massa van het
apparaat.
Houd componenten en hulpmiddelen ook op
ditzelfde potentiaal.
I
AVVERTIMENTO
Tutti IC e parecchi semi-conduttori sono
sensibili alle scariche statiche (ESD).
La loro longevita potrebbe essere fortemente
ridatta in caso di non osservazione della piu
grande cauzione alla loro manipolazione.
Durante le riparazioni occorre quindi essere
collegato allo stesso potenziale che quello
della massa dell'apparecchio tramite un
braccialetto a resistenza.
Assicurarsi che i componenti e anche gli
utensili con quali si lavora siano anche a
questo potenziale.
All ICs and many other semi-conductors are
susceptible to electrostatic discharges (ESD).
Careless handling during repair can reduce
life drastically.
When repairing, make sure that you are
connected with the same potential as the
mass of the set via a wrist wrap with
resistance.
Keep components and tools also at this
potential.
GB
WARNING
GB
Safety regulations require that the set be restored to its original condition
and that parts which are identical with those specified be used.
NL
Veiligheidsbepalingen vereisen, dat het apparaat in zijn oorspronkelijke
toestand wordt terug gebracht en dat onderdelen, identiek aan de
gespecifieerde worden toegepast.
D
Bei jeder Reparatur sind die geltenden Sicherheitsvorschriften zu beachten.
Der Originalzustand des Gerats darf nicht verandert werden.
Fur Reparaturen sind Original-Ersatzteile zu verwenden.
I
Le norme di sicurezza esigono che l'apparecchio venga rimesso nelle
condizioni originali e che siano utilizzati pezzi di ricambiago idetici a quelli
specificati.
F
Les normes de sécurité exigent que l'appareil soit remis a l'état d'origine et
que soient utilisées les pièces de rechange identiques à celles spécifiées.
“Pour votre sécurité, ces documents
doivent être utilisés par des

4. Mechanical instructions
4.1 CD Recording Drive Mechanism
The CD (Recording) Drive Mechanism, Tray Loading
Mechanism and Front-end Board part of the module (also
called CD R/W BASIC ENGINE) can have 2 different
executions. One is called FREYA the other RACOON. As
information and repair activity about RACOON is not defined
yet, this part is not included in this Service Manual.
Notice that both Mechanisms can not be interchanged, so
RACOON has to be replaced by RACOON, FREYA by
FREYA. As both parts can only be repaired with the help of
CDR-ComPair, the ComPair tool will contain the instructions
for both mechanisms.
