SAFETY INFORMATION
This service manual is intended for qualified service technicians; it is not meant for the casual do-it-yourselfer.
A Qualified technicians have the necessary test equipment and tools, and have been trained to properly and safety repair
complex products such as those covered by this manual.
Improperly performed repairs can adversely affect the safety and reliability of the product and may void the warranty.
If you are not qualified to perform the repair of this product properly and safety, you should not risk trying to do so
and refer the repair to a qualified service technician.
Where in a manufacturer's service documentation, for example in circuit diagrams or lists
of components, a symbol is used to indicate that a specific component shall be replaced only
by the component specified in that documentation for safety reasons, the following symbol shall
be used:
B - Safety Precautions for those who Service this Unit.

CAUTION: USE OF CONTROLS OR
ADJUSTMENTS OR PERFORMANCE OF
PROCEDURES OTHER THAN THOSE
C
SPECIFIED HEREIN MAY RESULT IN
HAZARDOUS RADIATION EXPOSURE.
CAUTION: THE USE OF OPTICAL
INSTRUMENTS WITH THIS PRODUCT
WILL INCREASE EYE HAZARD.
This product is a class 1 laser product, but
this product contains a laser diode higher
than Class 1. To ensure continued safety,
do not remove any covers or attempt to
gain access to the inside of the product.
D

1. SERVICE PRECAUTIONS
1.1 SERVICE PRECAUTIONS
A
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 about an internal sharp edge.
3. Be careful in handling ICs. Some ICs such as MOS type are so fragile that they can be damaged by
electrostatic induction.
4. Be careful in handing made from metal parts. There might be burr at the edge of it.

1.2 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
D
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:
E Parts numbers of lead-free solder:
GYP1006 1.0 in dia.
GYP1007 0.6 in dia.
GYP1008 0.3 in dia.
