IDENTIFYING VERSION NUMBER
1. Turn the power off.
2. While pressing the USER/PRESET Key and PHRASE
TRAINER ON/OFF Key simultaneously , turn the
power on.
The version number is displayed on the LCD.
3. Turn the power off to exit this mode.
LOADING FACTORY PRESET DATA
CAUTION !!
The user data cannot be saved to a sequencer via
MIDI.
Inform the user of this fact upon receiving a service
request.
1. Turn the power off.
2. While pressing the PARAMETER_R Key and
VALUE - Key simultaneously , turn the power on.
The " PRESET " is displayed on the LCD.
3. Press the WRITE copy Key .
The " write " flashes on the LCD for a while.
When the initialization is complete , the unit returns
the Play Mode.
To cancel the initialization at this time , turn the
power off.
TEST MODE
The ME-30 provides six test modes ; from MODE 1 to
MODE 6. Use whichever appropriate for your situation.
CAUTION !!
The user data cannot be saved to a sequencer via
MIDI. Inform the user of this fact upon receiving a
service request.
The test program will stop upon detecting a failure
component or circuit, and may not proceed to the next
step.
After taking a corrective action, restart the test
program from the beginning.
Connection to OUTPUTs:
Unless otherwise specifically instructed, channels L
and R are independently monitored: first connect the
plug from the measuring
instrument (oscilloscope or noise meter, whichever
appropriate) into OUTPUT R, next, replace the
instrument plug with a blank
(open) plug and then connect the instrument to
OUTPUT L.
Note that the channel R signal is connected to the
OUTPUT L socket through the switch on the OUTPUT
R socket. To obtain pure
"L" channel signal, the R socket switch must be turned
off.
