Troubleshooting
High-pitched ringing is heard
If you hear this in headphones:
Piano sounds that have a brilliant and crisp character contain substantial
high-frequency components that may sound as though a metallic ringing has
been added. This is because the character of an actual piano is being
faithfully reproduced, and is not a malfunction. This ringing is more obtrusive
if the reverb effect is applied heavily, so you may be able to minimize it by
decreasing the reverb.
If you don’t hear this in headphones:
It is likely that there is some other reason (such as resonances within the unit).
Please contact your dealer or a nearby Roland service center.

Low notes sound wrong, or are
buzzy
If you don’t hear this in headphones:
Performing at high volumes may cause the speakers or objects near the FP-4
to resonate. Fluorescent lights or glass doors may also resonate
sympathetically. In particular, this is more likely to occur for lower notes and
higher volumes. You can take the following measures to minimize
resonances.
• Locate the speakers 10–15 cm away from walls or other surfaces.
• Keep the volume down.
• Move away from the objects that are resonating.
If you hear this in headphones:
It is likely that there is some other reason. Please contact your dealer or a
nearby Roland service center.

With certain tones, the sounds may seem to be distorted.
