: The number of times which focus zero cross points
  of each layer when lens down.

PI Reference : The average of PI reference voltage. (hexadecimal

  number)

PI Peak

: PI peak level voltage. It performs only when disc
  type judgment is successful. (hexadecimal number)

It sets up so that it may judge as a disc type of specification of the
disc with which the set was inserted.

[5]: DVD single layer disc (8 cm)
[6]: DVD dual layer disc (0 layer, 8 cm)
[7]: DVD dual layer disc (1 layer, 8 cm)
[8]: DVD-RW disc (8 cm)

It sets up so that it may judge as a disc type of specification of the
disc with which the set was inserted.

[1]: CD disc (normal speed, 12 cm)
[2]: CD disc (double speed, 12 cm)
[3]: CD disc (normal speed, 8 cm)

[6]: CD-RW disc (double speed, 12 cm)
[7]: CD-RW disc (normal speed, 8 cm)
[8]: CD-RW disc (double speed, 8 cm)

It sets up so that it may judge as a disc type of specification of the
disc with which the set was inserted.

[1]: SACD Hybrid disc (SACD layer, 12 cm)
[2]: SACD Hybrid disc (CD layer, normal speed, 12 cm)
[3]: SACD Hybrid disc (CD layer, double speed, 12 cm)
[4]: SACD Hybrid disc (SACD layer, 8 cm)
[5]: SACD Hybrid disc (CD layer, normal speed, 8 cm)
[6]: SACD Hybrid disc (CD layer, double speed, 8 cm)

Be sure to perform the disc type setup before performing this item.

On this screen, the servo on/off control necessary for replay is
executed. Normally, turn on each servo from 1 sequentially and
when CLVA is turned on, the usual trace mode becomes active. In
the trace mode, DVD sector address or CD time code is displayed.
This is not displayed where the spindle is not locked.
The spindle could run overriding the control if the spindle system is
faulty or RF is not present. In such a case, do not operate CLVA.
