4) Turn on the power in the test mode (F. Offset adjustment is found) and move the pickup to the vicinity of the center
of the disc.
5) Turn on the DVD LD and perform Focus Close.
6) Automatically adjust Tracking Balance and perform Tracking Close.
7) Observing RF waveform levels of an oscilloscope, slightly turn skew adjusting screw A and adjust the oscilloscope
so that the levels can be maximized. Repeat this operation three times and fix the levels where they are maximized.
8) Mix agents A and B of adhesive 601 at a ratio of 1 to 1 and coat a specified part with both agents of the adhesive.
The adhesive is cured about 15 minutes. The coating position is shown in Fig.1.
Note) Do not apply the adhesive to the pickup section and the mechanical unit section other than the specified part.
Because heat is generated, do not mix a great number of adhesives at a time. Use the same number of
adhesives as the original one. Do not apply vibration until the adhesive is fixed.
9) Apply the screw lock to the head of the skew screw and secure it.
