1. SERVICE PRECAUTIONS
1.1 SERVICE PRECAUTIONS
A
1. You should conform to the regulations governing 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. Before disassembling the unit, be sure to turn off the power. Unplugging and plugging the connectors
during power-on mode may damage the ICs inside the unit.
3. Be careful in handling ICs. Some ICs such as MOS type are so fragile that they can be damaged by
electrostatic induction.

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 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:
GYP1006 1.0 in dia. B
GYP1007 0.6 in dia.
GYP1008 0.3 in dia.
