1.1 NOTES ON SOLDERING
1.2 NOTES ON REPLACING
1.3 SERVICE NOTICE
• 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.
Do NOT use a soldering iron whose tip temperature cannot be controlled.
The part listed below is difficult to replace as a discrete component part.
It the failure of suspected that are listed in the table, replace whole A

IC with heat-pad
• Performance pad was calibrated when the product is produced. If a relevant part is replaced with a new one, be sure to
carry out the calibration.
• For the method of calibration, refer to "PAD CALIBRATION MODE" in "6.1 TE
S
T MODE".
• If you forget to carry out the calibration, power for tapping the performance pad and degree of sound volume when
the sampler velocity mode is turned ON vary depending on the pad.
• Calibration execution data is memorized in the MAIN A
SS
Y. Be sure to carry out the calibration when the MAIN A
SS
Y is
replaced new one.

• Replacement of the NAND (IC2601) in the MAIN A
SS
Y is not possible during service, because writing of the MAC address
on the production line is required. Therefore, the NAND (IC2601) are not supplied as a service part. If the NAND is defective,
replace the whole MAIN A
