CAUSE
Focus point lost for at least 3ms.
CD7 indicates offtrack while radial
tracking is switched on.
The slide did not reach it´s inner pos.
(inner switch of CDM doesn´t close)
within approx. 6 seconds.
The slide did not come out of it´s inner
pos. (inner switch of CDM is open)
within approx. 250ms.
The DRAM controller was not able to
connect two consecutive audio frames.
The microcontroller had to perform a
direct audio connection that produces
audible clicks.
The offtrack values of CD7 don´t
decrease properly when jumping tracks,
the jump destination could not be found.
No valid subcode for approx. 230ms.
During start-up, the disc speed did not
reach 75% of the nom. speed within
approx. 6 seconds.
The focus point could not be found
within approx.
10 seconds (no valid TOC info), resp.
30 seconds (valid TOC info).
