If you experience problems, refer to the relevant item
and take the appropriate measures.
Power does not turn on
• Is the AC/AC power supply connected to an
outlet? ....................................................................
• Is the [POWER] switch turned on?
Turn on the rear panel [POWER] switch.
The power is turned on, but nothing is shown in
the LCD screen.
The TR functions normally when you play the key-
board or perform other operations.
• Due to changes in the surrounding temperature, the
LCD screen may on rare occasions be difficult or
impossible to read. If this occurs, perform the
following procedure. (
PG p.127)
1 Press the [EXIT] key three times, and press the
[GLOBAL] key.
2 Hold down the [EXIT] key, and press the [REC/
WRITE] key.
3 Rotate the [VALUE] dial to adjust the LCD
screen.
The power is turned on, but the LCD screen does
not display normally, or an error message is dis-
played. There is no sound when you play the key-
board, and the TR does not function normally.
• This type of problem may occur if a data writing
operation to internal memory was not completed
correctly, for example if the power of the TR was
turned off while a program or other data was being
written. If this occurs, use the following procedure
to initialize the TR's internal memory.
1 Turn off the power.
2 Hold down the [MENU] key and the [9] key, and
turn on the power.
The TR will be initialized, and data will be written
into internal memory. While the data is being writ-
ten, the LCD screen will indicate "Now writing into
internal memory."

mixer, or headphones?........................................
• Is your amp or mixer turned on?
• Is Local Control turned on?

On" check box. .............................................
