Installing wave expansion boards
• 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 boards.
• Before touching a 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 a board, grasp it only by its edges. Avoid touch-
ing 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 remove it from the instru-
ment.
• 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.
• Always turn the unit off and unplug the power cord before
attempting installation or removal of a circuit board.
• 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 E-80.
• Do not leave the bottom cover removed. After installing or remov-
ing a wave expansion board, be sure to replace the cover.
• Be careful not to cut your hand on the opening for installing a
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.
• Install only a circuit board of the Roland SRX or SR-G01 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 E-80 and all connected devices
and disconnect all cables, including the E-80’s
power cable.
(2) On the E-80, remove the screws shown in the fol-
lowing 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. Always orient the E-80 in such a way
that no buttons or controls get damaged.
When turning the E-80 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 one of the slots and at the
same time insert the board holder through the
hole of the wave expansion board.
The slot you choose is of no importance. Be aware,
however, that there are two expansion sound groups
(“A” and “B”) and that the slot you choose here speci-
fies which group you need to select on the front
panel.
