ory) has run down.
Contact your dealer or a nearby Roland service 
center to have the battery replaced.
Backup NG! Data in the TD-12’s memory may be corrupt-
ed. The TD-12’s internal backup battery (the 
battery used for saving User memory data) is 
fully drained; internal data has been lost.
Contact your dealer or a nearby Roland service 
center to have the battery replaced. Follow the

off for the MIDI device connected to the TD-

Check the power of the connected MIDI de-
vice.
