Troubleshooting
If the JUNO-Di does not function in the way you expect, first check the following points. If this does not resolve the problem, consult your dealer or a nearby
Roland Service Station.
* If any sort of message is being displayed on the screen during an operation, refer to “Error Messages” (p. 92).
Q The power does not turn on.
A Check the following points.
• Make sure that the JUNO-Di’s AC adaptor is correctly connected to
an AC outlet and to the rear panel power connector, and that the
adaptor itself and AC power cord are connected correctly (p. 17).
• If you connect the AC adaptor and turn on the power when
batteries are installed, the AC adaptor will be used preferentially.
Even if batteries are installed, the power will not turn on unless the
AC adaptor is connected to an AC outlet.
• If you’re using batteries, disconnect the AC adaptor from the JUNO-
Di. If batteries are installed, connecting or disconnecting the power
cord from the outlet or connecting or disconnecting the DC plug of
the AC adaptor while the JUNO-Di is turned on will cause the power
to turn off.
Q There is no sound.
A
Check the following points.
• Is the power for connected amps and speakers turned on?
• Could you have lowered the volume of your connected equipment?
• Is the [VOLUME] knob turned all the way down?
• Have connections been made correctly?
• Can you hear sound through headphones?
If there is sound in the headphones, it is possible that the
connection cables are broken, or that your amp/mixer has
malfunctioned. Check your cables and amp/mixer system once
again.
• If you do not hear sound when you play the keyboard, check
whether the Local Switch is turned OFF.
Make sure that the Local Switch setting is turned on (p. 76).
• Could the level of the tone (patch) be too low?
Check the level setting.
• The Part level settings may be too low.
Check the level of each part (p. 60).
• Are the Effect settings correct?
Check the Effect settings ON or OFF (p. 61).
Also use the included “JUNO-Di Editor” to check the effect level and
other settings.
• Could the volume have been lowered by pedal operations,
operations of the D Beam controller, or by MIDI messages (volume
or expression messages) received from an external MIDI device?
Q
A specific Part does not sound.
A
Check the following points.
• Has the volume level of the part been lowered?

Q
The sound is distorted.
A
Check the following points.

If the sound for a specific tone (patch) or part is distorted, lower the
volume level on that part.
• If all sounds are distorted, use the [VOLUME] knob to lower the
volume level.
• Could the Output Gain be excessively high?
Check the system setting “SOUND” (p. 75).

Have the Coarse or Fine parameters been set for specific Parts?
Check the Coarse parameter and Fine parameter settings.
