Introduction / Technical Specifications

General 1.3.2

CD Recording Mozart Module is a module for playback of

Audio/Data CDs (incl. CD RM) and recording on Audio CD-

R 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.

1.3.3

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.
