WARNING!
The AEL (accessible emission level )of the laser power output is less than CLASS 1
but the laser component is capable of emitting radiation exceeding the limit for
A
CLASS 1.
A specially instructed person should do servicing operation of the apparatus.
Laser diode characteristics
Wave length:
DVD:660 nm to 670 nm
CD:780 nm to 800 nm
Maximum Output
DVD : 1.27 mW(Emitting period :9 sec.)
CD : 6.26 mW(Emitting period : unlimited) B
Additional Laser Caution
Transistors Q1103 and Q1104 in PCB drive the laser diodes for DVD and CD
respectively. When Q1103 or Q1104 is shorted between their terminals,
the laser diodes for DVD or CD will radiate beam. If the top cover is removed C
with no disc loaded while such short-circuit is continued, the naked eyes may
be exposed to the laser beam.

1. SERVICE PRECAUTIONS
1.1 SERVICE PRECAUTIONS
A - Service Precaution
1. You should conform to the regulations govering the product (safety, radio and noise, and other regulations),
and should keep the safety during servicing by following the safety instructions described in this manual.
2. Be careful in handling ICs. Some ICs such as MOS type are so fragile that they can be damaged by
electrostatic induction.
3. Before disassembling the unit, be sure to turn off the power. Unplugging and plugging the connectors
during power-on mode may ICs inside the unit.
4. To protect the pickup unit from electrostatic discharge during servicing, take an appropriate treatment
(shorting-solder) by referring to "the DISASSEMBLY".
5. After replacing the pickup unit, be sure to skew adjustment.
6. During disassembly, be sure to turn the power off since an internal IC might be destroyed when aconnector
B is plugged or unplugged.

1.2 NOTES ON SOLDERING
NOTES ON SOLDERING
For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit.
Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs A
accompanied by reworking of soldering.
Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 C.
Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 C in general, although
the temperature depends on the heat capacity of the PC board on which reworking is required and the weight of the tip of
the soldering iron.
Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting
temperatures (hard to melt/easy to harden).
The following lead-free solders are available as service parts:
Parts numbers of lead-free solder: B
GYP1006 1.0 in dia.
GYP1007 0.6 in dia.
GYP1008 0.3 in dia.
