1.1 NOTES ON SOLDERING

• For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit.
A
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).
B
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 IMPORTANT SERVICE NOTICE

1. To replace the MAIN PWB Unit, perform the items 9 - 12 of "8.1 UPDATING SOFTWARE" and confirm the version: it is neces-
sary to update with a disc to the latest version if the MAIN PWB Unit version is old.
C
2. The IC7201 and IC8505 cannot be replaced because they have the BD-playback key already written. Accordingly, the IC8502
that has the software written together with the IC8505 cannot be replaced either. Keep also in mind that the IC8503 cannot
be replaced either because of the model information on it.

1.3 CHECK S7202 SLIDE SWITCH POSITION
