Due to changes in the surrounding tempera-
ture, the display may on rare occasions be diffi-
cult or impossible to read. If this occurs,
perform the following procedure.

[GLOBAL] button will blink, and the Global
mode Update Global Setting dialog box will
If you are unable to read the display, or if the
Update Global Setting dialog box does not
appear, check whether the [GLOBAL] button
is blinking. If the [GLOBAL] button is lit or
dark, the microX may be writing data that
was received from an external connected
MIDI device, or may be responding to a
request for output. If so, make sure that the
microX is not writing data from an external
connected MIDI device or transmitting data

power of the microX off and on again, and
repeat this procedure from step 1.

3. Press the [MENU/OK] button.
The LCD contrast setting will be memorized.
Note: Other global settings will also be memorized
at this time.
The power is turned on, but the display
does not display normally, or an error
message is displayed. There is no sound
when you play the keyboard, and the
microX does not function normally.
This type of problem may occur if a data writ-
ing operation to internal memory was not com-
pleted correctly, for example if the power of the
microX was turned off while a program or
other data was being written. If this occurs, use
the following procedure to initialize the
microX's internal memory.
1. Turn off the power.
2. Hold down the [ENTER] button and the [0]
button, and turn on the power.
The microX will be initialized, and the factory
preload data will be written into internal
memory. While the data is being written, the
display will indicate "Now writing into
internal memory."
