About the Backup Battery
A backup battery (lithium battery) is used to keep internal data (settings) from being lost, even when
the power cord is unplugged. Internal data will be lost when battery power is depleted, so it is recom-
mended that data be stored to an external data recorder such as the Yamaha MIDI Data Filer MDF3
(

page 24), or keep records of settings in memo form. The average battery life span is about 3
years. When replacement becomes necessary contact the music store where the unit was pur-
chased, or a qualified service representative, to perform the replacement.
• Do not attempt to replace the backup battery by yourself.
• Keep the backup battery out of reach of children.
• “
E5

• Data may be lost if the unit is improperly handled or if repairs are performed.
