IMPORTANT PRELIMINARY NOTES
Observe these important preliminary notes before using your instrument.
AVOID PLACING DISKS NEAR MAGNETS - Do not place floppy disks on top of speakers, near mag-
nets, telephones or other sources of electromagnetic fields. The disk contents could be damaged.
UPDATEABLE OPERATING SYSTEM - two disks containing the operating system are supplied with
the instrument. The disks can contain a more recent version of the operating system than the one
contained in the instrument’s Flash ROM.
To load the operating system contained in the floppy disks:
(1) turn off the instrument, (2) insert OS-disk 1 in the drive, (3) turn on the instrument, (4) When the
message “Loading OS-DISK clears ALL MEMORY !! < Enter to load / Escape to abort >” appears, press
ENTER to start the OS update, (5) when the message, “INSERT NEXT OS-DISK please < Enter to load
>” appears, extract the first disk, insert OS-Disk 2 and press ENTER to continue (6) when the operation
is complete, the instrument sets to the default Style/Preset situation. After completing this process,
proceed with the reset that follows below to ensure proper operation. Remember to extract the second
disk and store both OS-disks in a safe place.
SYSTEM RESET
SYSTEM RESET - If the data contained in the instrument’s memory has been damaged, either by being
exposed to the effects of a strong magnetic field, or other unknown reason, the instrument may not
operate properly. The remedy is a System Reset:
(1) press and hold the UPPER 1 selector button located to the right of the LCD display, (2) simultane-
ously press the three buttons 2, 3 & 4 of the PROGRAMMABLE PADS section while still holding the
UPPER 1 selector button, (3) the message «System Reset» appears for an instant then the instrument
resets to the factory-set situation. All user-programmed data is irremediably lost.
