Additional Laser Caution

1. Laser Interlock Mechanism
The position of the switch (S601) for detecting loading
state is detected by the system microprocessor, and the
design prevents laser diode oscillation when the switch
(S601) is not on CLMP terminal side (CLMP signal is OFF
or high level.). Thus, the interlock will no longer function if
the switch (S601) is deliberately set to CLMP terminal side
(low level).
The interlock also does not function in the test mode * .
Laser diode oscillation will continue, if pin 1 of M51593FP
(IC101) on the PRE-AMP BOARD ASSY mounted on the
pickup assembly is connected to GND, or pin 19 is
connected to low level (ON), or else the terminals of Q101
are shorted to each other (fault condition).
2. When the cover is opened with the servo mechanism block

removed and turned over, close viewing of the objective
lens with the naked eye will cause exposure to a Class 1
laser beam.

In the Test Mode, since each servo circuit operates independently, playing back a disc
requires that your operate the keys in the correct order to close the servo circuits.

3-5-1. Focus Offset Adjustment

Test Point CN354 - pin 6 (FE)
Adjustment Point RECORD and REC MUTE buttons
Adjustment Value 0 mW ± 10 mW
[Procedure]
(1) Press the AUTO/MANUAL button until “01_F4” appears on the FL display.
(2) Adjust with the RECORD and REC MUTE buttons until the value for Pin 6 of CN354 is 0 mV ± 10 mV.
(3) Press the SET button to register the adjustment. Once the adjustment is registered with the SET button, “?” will
disappear.

3-5-2. M-S Mix Ratio Adjustment

Test Point CN102 - pin 3 (TE) and pin 4 (MPP)
Adjustment Value Adjust until the value of output signal from pin 3 (TE) and pin 4 (MPP) of CN102 are the same,
or the differential output of these signals is minimal.
[Procedure]
(1) Press the AUTO/MANUAL button so that “02_F3” appears on the FL display.
(2) Press the FINALIZE button for focus-in.
(3) Press the PLAY button for CAV-servo spindle kick (the status where the spindle rotates with the focus servo on and
tracking servo off).
(4) Adjust with the RECORD and REC MUTE buttons until the value to be reached is obtained.
(5) Press the SET button to register the adjustment.
Once the adjustment is registered with the SET button, “?” on the FL display will disappear.
(6) Press the STOP button to stop the unit.
NOTE: For adjustment, use the following circuits.

Test Point CN354 - pin 1 (RF)
Adjustment Point DIGITAL SYNCHRO, RECORD and REC MUTE buttons
Adjustment Value Adjust until the RF jitter is minimal or that the eye pattern of the RF waveform is most open.
[Procedure]
(1) Press the DIGITAL SYNCHRO button in Stop mode.

NOTE: Make sure that the unit is in Stop mode.
(2) Check that “48” appears on the FL display.
(3) Press the AUTO/MANUAL button so that “04_34” appears on the FL display.
(4) Press the FINALIZE button for focus-in.
(5) Press the PLAY button for CAV-servo spindle kick.
(6) Press the PAUSE button to close the tracking servo, then set the unit to Playback mode.
(7) Adjust with the RECORD and REC MUTE buttons until the above adjustment value to be reached is obtained.

Notes) • PCMD is an MSB first, two's complement output.
• GTOP is used to monitor the frame sync protection status. (High: sync protection window released)
• XUGF is the negative pulse for the frame sync derived from the EFM signal. It is the signal before sync protection.
• XPCK is the inverse of the EFM PLL clock. The PLL is designed so that the falling edge of XPCK and the EFM signal transition point coincide.
• GFS goes high when the frame sync and the insertion protection timing match.
• RFCK is derived with the crystal accuracy. This signal has a cycle of 136us.
• C2PO represents the data error status.
• XROF is generated when the 32K RAM exceeds the ±28 Frame jitter match.
