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.
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.
Do NOT use a soldering iron whose tip temperature cannot be controlled.

1.2 NOTES ON REPLACING

1.3 SERVICE NOTICE

Calibration of performance 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 TEST 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 ASSY. Be sure to carry out the calibration when the MAIN ASSY is
replaced new one.
About PADB ASSY of sensors (Pressure sensitive)
• Don`t touch the black parts of the PADB ASSY (side-A) and black mat parts of the Sensor (16 pieces each, which are
E
pressure sensitive ) with your bare hands.
Clear the dust between the PADB ASSY, Sheet, Sensor and Button by air blast when you assemble the sensor.
About SEQB ASSY and BARB ASSY
• Clear the dust between inside of the Cap, Buttons and PCBs by air blast to remove the foreign particles when you assemble
SEQB ASSY or BARB ASSY.
About the NAND:Flash ROM IC(IC1200) in the MAIN ASSY
• Replacement of the NAND (IC1200) in the MAIN ASSY is not possible during service, because writing of the MAC address
on the production line is required. Therefore, the NAND (IC1200) are not supplied as a service part. If the NAND is defective,
replace the whole MAIN ASSY.
Caution: Control Panel and Chassis unit in the state that has wire does not open 180 degrees.
