Data Backup & Initialization - Yamaha Portatone PSR-550 Service Manual

PSR-550
DATA BACKUP & INITIALIZATION
Data Backup
Except for the data listed below, all PSR-550 panel settings are reset to their initial settings whenever the power is turned
on. The data listed below are backed up - i.e. retained in memory - as long as an AC adaptor is connected or a set of batteries
is installed.
• User Style data
• User Pad data
• Registration Memory data
• Registration Memory Bank Number
• Registration Memory/One Touch Setting status
• Freeze on/off
• MIDI Transmit settings
• MIDI Receive settings
• Voice Set on/off
• Voice L (Voice Change, Mixer)
• Fingering mode
Even though these settings are retained in memory, you
should save them — and all your important data — to
floppy disk for permanent, safe storage. To save all of the
data types listed above to floppy disk, use the Save
operation and select "All" as the file type.
Data Initialization
All data can be initialized and restored to the factory preset condition by turning on the power while holding the highest
(rightmost) white key on the keyboard. "Now Initializing" will appear briefly on the display.

• Split Point
• Sustain on/off
• Upper Octave setting
• Pitch Bend Range
• Scale Tuning
• Transpose
• Footswitch Function, Polarity
• Touch on/off, Sensitivity
• Multi Pad setting
• Master Tuning
• Metronome on/off
All data listed above will be lost if the power is interrupted
— in other words, if the power is turned off, the AC adaptor
is disconnected and the batteries are removed. When this
happens, the next time you turn on the PSR-550, a "Clear
Backup" message appears in the display, the Data
Initialization operation (below) is automatically executed,
and the PSR-550 is set to the Style mode.
CAUTION
• All registration and User Style/Pad memory data, plus the
other settings listed above, will be erased and/or changed
when the data initialization procedure is carried out.
• Carrying out the data initialization procedure will usually
restore normal operation if the PSR-550 freezes or begins
to act erratically for any reason.
