1. SERVICE PRECAUTIONS

1.1 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
accompanied by reworking of soldering.
• Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 ºC.
Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 ºC 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.
Do NOT use a soldering iron whose tip temperature cannot be controlled.
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.
GYP1007 0.6 in dia.
GYP1008 0.3 in dia.

1.2 NOTE ON DISASSEMBLING/REASSEMBLING

• For improvement of audio quality, many special screws and acetate tapes are used in this unit. Be careful when
disassembling/reassembling this unit, and be sure to restore the unit to its original state.

1.3 NOTE ON REPLACING IC9011

• As IC9011 (ROM) on the SERVICE MAIN Assy is fixed to the board with a special adhesive, it is not provided as a
service part. If replacement of IC9011 (ROM) is required, replace the entire SERVICE MAIN Assy.

1.4 NOTE ON REPLACING THE TRAY PANEL BASE AND TRAY ALUMINUM

• As the tray aluminum (VAH1467) and the tray panel base (VNK6455) are strongly adhered with double-back tape,
replace both parts when either needs to be replaced.
For attachment, adhere the tray aluminum (VAH1467) so that it is placed at the center of the tray panel base (VNK6455).
