Troubleshooting
High-pitched ringing is heard
Is the speaker cable connected correctly? p. 18
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 LX-10 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.

If you set the volume to the maximum setting, the sound may be distorted
depending on how you perform.
If this occurs, turn down the volume.
Alternatively, lower the master gain.

The pitch or tone quality of the
piano sound seems strange in
certain registers
Since the inherent characteristics of a grand piano are being faithfully
reproduced, it may sound as though certain harmonics are being emphasized in
some registers, and as a result the pitch or tone quality may be perceived as being
somewhat unusual. However, this is normal and does not indicate a malfunction.

Mechanical, click-clack sound
heard when playing the
keyboard
The PHA (Progressive Hammer Action) keyboard that is incorporated in this
product was developed with the goal of accurately reproducing the natural touch
of a grand piano. This means that no springs are used---movement occurs as a
result of the weight of the hammers. Consequently, if you play the keys somewhat
forcefully, you may notice the sound of the hammers as they move, just as you
would on an acoustic piano.

Song does not play correctly
Song won’t play
Could the screen be indicating “OK to delete Song?”
You can’t play back an internal song if internal memory contains performance
data you recorded. Erase the performance data you recorded before you play
back the song.
