The detection sensitivity for the fault detection function is set in four
levels.
A fault status is detected when a status where a normal signal can
not be detected consecutively for 5 tracks over the following track
values.
0: 1/2
1: 3/4
2: 7/8
3: 15/16

The strength of the frequency pull-in operation of the PLL phase
comparison characteristic expansion function is controlled in four
levels. The action is weakest with 0 and strongest with 3.
When the data acquisition ratio at the time of special playback is bad,
it can be improved by controlling this parameter.

Setting of the initial value of the output voltage adjusting the VCO
center frequency
Adjustment is performed automatically in standby mode, but the time
required for automatic adjustment can be reduced by setting this
value in advance to a suitable value.
The automatically adjusted value is read out and set.
• Read-out is possible only at the time of EJECT, STANDBY-OFF.
Yes Use for electrical adjustment
