LASER BEAM SAFETY PRECAUTIONS
CLASS 1 LASER PRODUCT
CAUTION
Invisible laser radiation when the unit is open.
Do not stare into beam.
CAUTION: USE OF ANY CONTROLS, ADJUSTMENT, OR
PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN
MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.
Do not look directly at the laser beam
coming from the pickup or allow it to
strike against your skin.
This compact disc player uses a pickup that emits a laser beam. The laser beam is emitted from the
location shown in the figure. When checking the laser diode, be sure to keep your eyes at least 1 foot away
from the pickup lens when the diode is turned on. Do not look directly at the laser beam.
CAUTION:
Using controls and adjustment, or doing procedures other than those specified herein, may result in
hazardous radiation exposure.

SAFETY PRECAUTIONS
This symbol is intended to alert the user to
the presence of uninsulated "dangerous
voltage" within the product's enclosure that
may be of sufficient magnitude to consti-
tute a risk of electric shock to persons.
This symbol is intended to alert the user to
the presence of important operating and
maintenance (servicing) instructions in the
literature accompanying the appliance.
Caution: To prevent electric shock do not use this
(polarized) plug with an extension cord, recep-
tacle or other outlet unless the blades can be
fully inserted to prevent blade exposure.
Attention: Pour prevenir les chocs electriques ne pas

WARNING partie a decouvert.
To prevent fire or shock hazard, do not
expose the unit to rain or moisture.
HANDLING LASER PICKUP
The laser diode in the optical system of this player can be damaged by electrostatic discharge from
your clothes or your body. Proper electrostatic grounding for service personal is required during servicing.
BEFORE REPAIRING THE COMPACT DISC PLAYER
Preparation
Human Body Grounding:
Many of the components used in this compact disc player, including the laser pickup, are sensitive to
electrostatic discharge. Service personal should be grounded with an electrostatic armband (1 Mohm).
Caution:
Static charge on clothing does not escape through a body grounding wrist band.
Be careful not to contact the pickup or electrical components with your clothing.
Workbench and Tool Grounding:
A properly-grounded electroconductive plate (1Mohm) or metal sheet should be fitted to the workbench
surface. Tools and instruments (such as soldering irons and scopes) should be grounded to prevent AC
leakage.
Note: Laser diodes are so susceptible to damage from static electricity that, even if a static discharge does
not ruin a diode, it can shorten its life or cause it to work improperly.

The tracking error output of E and F is given to Pin 25 (TEOUT). C8 is required for
oscillation-proof. R10 is chosen such that TEOUT of Pin 25 become 1.4Vp-p.
During alignment procedure, the DSP IC (MN662790) will adjust the tracking balance
voltage VTBAL from Pin 31. VTBAL varies with reference to the center voltage VREF2 (=1.65 V)
within ±0.5 V.
The tracking gain will change according to the type of disc. For normal disc or CDR disc,
VGCTRL is set to VREF2; for CDRW disc VGCTRL is set to VREF2 - 0.75 V. At the same time, the
focus gain is changed too.

The signals A, B, C and D input from PDIC are composed into the RF signal by the RF
Addition Amp, then output from RFOUT of Pin 5. This Amp is designed so that RFOUT is
about 0.5 Vp-p for normal CD disc (about 0.4 Vp-p for CDR and 0.12 Vp-p for CDRW).
RF signal from Pin 5 is then input to the AGC block through the EQ block (the EQ
characteristic is fixed for single speed operation in this design). It is then gain-controlled
and output to Pin 10 ARF. The AGC block maintains the output level of ARF to about
1.0Vp-p for all types of disc. C38 connected to Pin 9 is for the AGC loop filter.
The RF Detection block detects the amplitude of the RF signal inputted from the EQ block.
Inputted RF signal is detected after passing through a high-pass filter. Detection level is
changed in accrodance with the voltage of GCTRL Pin 28.
The ENV detection block detects the fluctuation of the 3T-composition in the RF signal
which is needed for focus balance adjustment. C39 connected to Pin 11 forms a filter for
detecting the signal fluctuation. The ENV output signal from Pin 12 is filtered by C29.

The laser diode has large negative temperature characteristic in its optical output when
driven with a constant current on laser diode. Therefore, the output on processing monitor
photo diode, must be a controlled current for getting regular output power, thus the APC
(Auto Power Control) circuit is composed.

For models: FL8350/FL8550/FL8380 TIP# HKTT2003-06
Complaint: Unit Will Not Play or Recognize a Disc, "Skipping".
Possible Problem: Misalignment of the top cover and rear panel.
To test, attempt to play the unit with the top cover OFF. If symptoms persist, troubleshoot further. If the
unit will play with the cover OFF, the problem is caused by a misalignment of the top
