Data Backup; Multi Play Mode - Yamaha SY99 Owner's Manual

Location
Avoid placing the SY99 in direct sunlight, or in locations where it will be subjected to temperature extremes,
moisture, excessive dust, or heavy vibration.

Data backup

It is possible for data in internal memory to be lost as a result of inappropriate operation or other reasons. We
recommend that you keep backups of important voice, multi, system, sequencer, sample, MDR data on a floppy
disk or memory card (MCD64). It is also possible for the data in a floppy disk or memory card to be lost as a
result of static electricity, magnetic fields, or other causes. For very important data it is always a good idea to
make double backups.

Multi Play mode

If many multi-element voices are played simultaneously when in Multi Play mode, note timing may sometimes
be slightly delayed. In such cases, select voices that use fewer elements, or reduce the number of notes.
Backup battery
The SY99 contains a backup battery which preserves settings such as for voice and multi data when the power
is turned off. The life of this battery is approximately 5 years. However depending on the date of purchase, battery
life may be shorter than this.
If the backup battery runs low, a message "Change internal Battery!" will appear in the display when the
power is turned on. If the backup battery runs down completely, the voice and multi data will be lost, so when this
display appears, immediately store your data to a floppy disk or memory card and contact the dealer where you
purchased the SY99 or your nearby Yamaha service center to have the battery replaced. Again, when the battery
is replaced, all internal voice data, multi data, and data contained in the MDR/sample RAM area will be lost. Be
sure to save the data to a floppy disk or memory card before having the battery replaced.
