.
About replacement of Optical Device.
Before exchanging the Optical Device, Check the RF level, Jitter, Eye pattern, Focus gain and
Tracking error. When Optical Device is meet the specification, Playback the PS1 testing disc
“QA-DISC” or “AGING DISC” for checking the double speed and sled mechanism ability.
Optical Device should have to no exchange when spacification and ability are satisfied.
