The 1st time carries out TOC
position memory by stepper
accuracy after power on.
If it is a program area, it
jump-backs to TOC area.
When TOC read is completion

CD-DRIVE
As CD-DRIVE is same as CDJ-200, CDJ-800MK2' Function is as same it too.

When a check fails three times,display EJECT.
When a check fails one times,S-curve waveform is
measured in RF gain up.
When S-curve waveform level is 0.88Vp-p or
less,focus on is carried out by OEIC and RG gain up.
