Appendix: Troubleshooting / Data Backup & Initialization
PROBLEM
The reverb and chorus types can not
be changed by changing the registra-
tion memory number.
Individual registration, song memory, or
multi pad data transmitted via bulk
dump from an external sequencer or
other device is not received by the
PSR-520.
Cartridge data cannot be selected or
cannot be played back correctly.
Appendix: Data Backup & Initialization
Except for the data listed below, all PSR-520 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.
• Registration Memory data
• User Song data
• User Pad Kit data
• Remote Channel
• Keyboard Out
• Song Out
• Accomp Out
• External Clock
Data Initialization
All data can be initialized and restored to the factory preset condition by
turning ON the power while holding the [–/NO] and [+/YES] buttons. "CLr:
Backup" will appear briefly on the display.

ACCOMP FREEZE function is turned ON. The reverb and chorus types are
memoried as accompaniment parameter. Press the [ACCOMP FREEZE] button
to turn OFF it.
Transmit the data with no more than a 2-second break between blocks, or trans-
mit as entirely separate data.
Make sure that an appropriate Yamaha Music Cartridge is properly plugged into
the cartridge slot (page 60)
The electrical contacts on the Music Cartridge are affected with dust. Insert and
remove the Music Cartridge several times. This may solve the problem. If the
problem still happens, wipe and clear the electrical contacts on the Music Car-
tridge with a dry soft cloth.
