Installing a wave expansion board
• 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.
• Before you touch the board, 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.
• When handling the board, grasp it only by its edges. Avoid
touching any of the electronic components or connectors.
• 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 Phillips screwdriver that is suitable for the size of the screws.
If an unsuitable screwdriver is used, the head of the screws may be
stripped.
• To remove a screw, rotate the screwdriver counter-clockwise. To
tighten the screws, rotate the screwdriver clockwise.
• When installing wave expansion boards, remove only the specified
screws.
• Be careful that the screws you remove do not fall into the interior
of the G-70.
• Do not leave the bottom cover removed. After installation of the
wave expansion board, be sure to replace the cover.
• Be careful not to cut your hand on the opening for installing the
board.
• Do not touch any of the printed circuit pathways or connection
terminals.
• 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.
• When circuit board installation is complete, double-check your
work.
• Always turn the unit off and unplug the power cord before
attempting installation of the circuit board.
• Install only the specified circuit board(s) (Roland SRX series).
Remove only the specified screws.
How to install a wave expansion board
(1) Before installing a wave expansion board, turn off
the power of the G-70 and all connected devices,
and disconnect all cables, including the G-70’s
power cable.
(2) On the G-70, remove only the four screws shown
in the following diagram, and detach the cover.
The cover is located on the bottom panel.
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. Always orient the G-70 in
such a way that no buttons or controls get damaged.
When turning the G-70 upside-down, handle with
care to avoid dropping it, or allowing it to fall or tip
over.
(3) Plug the connector of the Wave Expansion Board
into the connector of the slot, and at the same
time insert the board holder through the hole of
the wave expansion board.
(4) Use the installation tool supplied with the wave
expansion board to turn the holders in the LOCK
direction, so the board will be fastened in place.
