3-3. ATTENTION
Dielectric voltage withstand of Optical Device.
After repair complete. Dielectric voltage withstand test and Insulation resistance test to be conducted
according to the regulation of IEC-65 EN60065 or UL1492 or
.
About replacement of Optical Device.
Check the specification of RF level, Jitter, Eye pattern, Focus gain and Tracking error using Check jig before
replaceing the Optical Device.
When Optical Device satisfied those specification, Playback QA DISC or AGING DISC for checking double
speed ability and sleding mechanism.
