• 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.

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.
