Installing the Plug-in Board

• When installing or uninstalling the XG Plug-in board, the System Setup and

Multi Part settings of the MU128 are initialized to their default values.  Always
save your important settings to a computer or MIDI data filer (such as MDF3)
by using the Dump Out functions beforehand.

• To avoid injury, be careful while handling and installing/uninstalling the XG

Plug-in board.

1  Turn off the power of the MU128 and any connected devices.

Also remove all connected cables from the MU128, and unplug
the power adaptor.

• When installing/uninstalling an XG Plug-in board, and the power of the MU128

has been on for some time, make sure to let the installed board(s) cool down
for a while after turning the power off.

• Make sure to unplug the power adaptor from the MU128 before installing/

uninstalling the board.  Attempting to install/uninstall the board while power
adaptor is still connected may damage the board and/or the MU128.

2  Remove the large screw from the expansion bay cover on the rear

panel, and remove the cover (as shown below).

• Since the screw is tightened securely at the factory, you may need to use a

screwdriver to loosen it at first.  Normally, it can be fastened and removed
simply by using your fingers.

3  Remove the XG Plug-in board from its protective packaging.

Before handling the XG Plug-in board, make sure to discharge any static elec-
tricity from your body or clothes by touching a grounded metal surface.  Also be
careful not to touch any of the parts or connectors of the board.
