The password will be supplied to only service HQ, and 
service center name, q’ty and all of software registered 
information should be maintained by service HQ, and 
Audio will ask to report the registration information.
Optical device (KEM480AAA) for BD requires precise read out 
functions and secure contents protection system for more than past 
DVD/CD.
Therefore, in the case repaired as follows, the writing work of the 
OP data is necessary.
•  When the optical device (KEM480AAA) is replaced (The 
MB148 board doesn’t replace).
•  When both the optical device (KEM480AAA) and MB148 
board are replaced.
•  When the MB148 board is replaced (The optical device 
(KEM480AAA) doesn’t replace) (In this case, do the work of 
“3. Optical device (KEM480AAA) replacement” other than 
the replacement of new optical device).
Note: The servo adjustment is done while writing the OP data. The manual 
adjustment is unnecessary.
 
  LD ON TIME history doesn’t carry over.
 
  Do not touch any optical block parts, turn table and during 
replacing. BD laser diode is very sensitive.
1. Preparation
1-1. ESD Countermeasure
It is necessary to confi rm the state of static electricity in the work 
space before the repair is started.
The static electricity resistance of the BD laser is weaker than that 
of the DVD/CD laser.
Do work space and worker’s ESD countermeasures to prevent 
destruction by ESD.
