Installing the Wave Expansion Board
An optional Wave Expansion Board (SRX series) can be installed in
the MC-909.
Waveform data, patches and rhythm sets are stored on the Wave
Expansion Board, so you can increase the number of available
sounds by installing the board in the MC-909.
Cautions When Installing a
Wave Expansion Board
901
• To avoid the risk of damage to internal components that can be
caused by static electricity, please carefully observe the following
whenever you handle the board.
1
• Before you touch the board, always first grasp a metal object
(such as a water pipe), so you are sure that any static
electricity you might have been carrying has been discharged.
2
• When handling the board, grasp it only by its edges. Avoid
touching any of the electronic components or connectors.
5
• Save the bag in which the board was originally shipped, and
put the board back into it whenever you need to store or
transport it.
• Use a Philips screwdriver that is suitable for the size of the screw
(a number 2 screwdriver). If an unsuitable screwdriver is used,
the head of the screw may be stripped.
• To remove a screw, rotate the screwdriver counter-clockwise. To
tighten the screws, rotate the screwdriver clockwise.
fig.Screw.e
• Be careful that the screws you remove do not drop into the
interior of the MC-909.
• Be careful not to cut your hand on the edge of the cover or the
opening edge while removing the cover.
911
• Do not touch any of the printed circuit pathways or connection
terminals.
912
• Never use excessive force when installing a circuit board. If it
doesn’t fit properly on the first attempt, remove the board and try
again.
913
• When circuit board installation is complete, double-check your
work.
914
• Always turn the unit off and unplug the power cord before
attempting installation of the circuit board (SRX series; Quick
Start p. 2).
915
• Install only the specified circuit board (SRX series). Remove only
the specified screws (p. 142).
928
• When turning the unit upside-down, get a bunch of newspapers
or magazines, and place them under the four corners or at both
ends to prevent damage to the buttons and controls. Also, you
should try to orient the unit so no buttons or controls get
damaged.
929
• When turning the unit upside-down, handle with care to avoid
dropping it, or allowing it to fall or tip over.
• Do not leave the bottom cover removed. After installation of the
Wave Expansion Board is complete, be sure to replace the cover.
