1. SERVICE PRECAUTIONS
1.1 NOTES ON SOLDERING
1.2 NOTES ON PARTS REPLACEMENT
• 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.
When youreplacing Front panel, JWring, it is necessary to remove Front panel.
NITTO No. 500
(5 mm × 30 mm)
NITTO No. 500
(5 mm × 40 mm)
When detaching the front panel
The front panel and the Chassis Assy are secured with 10 pieces of double-back tape at the locations shown in the illustration below.
Slowly peel off the tape, taking care that youwill not deform the front panel.
When reattaching the front panel
1Neatly remove any residue of double-back tape from the back of the front panel and the Chassis Assy.
2Stick 10 pieces (5 mm) of NITTO No. 500 double-back tape to the locations shown in the illustration belowthen remove the paper liner.
Note: Even if double-back tape was not used in the initial state, be sure to attach double-back tape when reattaching the front panel.
Before securing the front panel to the Chassis Assy with screws, never press on the places where the pieces of double-back tape are
attached.
Press on the places where the pieces of double-back tape are attached after securing the front panel to the Chassis Assy with screws.
Notes:
• Do not reuse the double-back tape.
• Put the double-back tape on the Chassis Assy side.

1.3 ABOUT DEMO MODE
Four washers have been added to the screw-mounted parts of the Pad & FSR Plate Assy to solve the problem that
a performance pad is only pressed halfway although it is fully pressed. This problem was revealed during production.
This emergency measure will be taken care of in the future, but the exact date when the improved products will be produced is
not determined yet. At least the first 20,000 products will have the added washers.
The initial service parts for the Pad & FSR Plate Assy will also require attachment of washers.
To prevent the washers from not being attached during replacement of the Pad & FSR Plate Assy with the one for service,
the Pad & FSR Plate Assy and the washers are to be enclosed in the same package as a kit.
The part number of the kit for service is GXX1374.
When a newPad & FSR Plate Assy for service is to be reassembled, be sure to attach the enclosed 4 washers to
the screw-mounted parts. (See the figure below.)
Note on Replacement of the Pad & FSR Plate Assy
Pad & FSR Plate Assy
Attach the washer.
This unit will automatically enter Demo mode if it is left unoperated for 10 minutes in Normal Operation mode, and a
demonstration with LED illumination will start.
To cancel this mode, operate any control or button of this unit.
To disable Demo mode, change the setting in the settings of Utilities mode 1. (For details, refer to the operating instructions.)
