  • Page 12 • Hold pedal USERS DATA SAVE • Audio cables x 2 • MIDI cable x 1 Here’s how to back up (save) all settings of the JUNO-D on an external MIDI sequencer. Test items Procedure The JUNO-D has the following tests. For details on each test, refer to the corresponding item.
  • Page 13 While holding down the three buttons [DESTINATION TONE] + [ENV or DRAM:OK EEPROM:OK BALANCE/LFO] + [TAP TEMPO], turn on the power of the JUNO-D. The top page of Test mode will appear.

  • Page 14 Before you begin this test, verify that there are no objects within 50 cm of the JUNO-D. (If any such objects are within this range, the settings cannot be made Move the bender all the way to the right; if a value of “127” is reached, a correctly.)
  • Page 15 When all switches have been pressed, you will automatically proceed to the next test. If there is important data you’ve created that’s stored in the JUNO-D’s internal memory, you must note that all such data will be discarded when a Factory Reset is performed.
