Troubleshooting
The table below summarises issues that may be experienced with the ES520 digital piano, explaining the typical
cause(s), and recommended solution(s).
Issue
Possible Cause and Solution
Page no.
Po
w
er
The instrument does not turn on.
Check that the AC power adaptor is firmly attached to the instrument,
and connected to an AC outlet.
The instrument turns itself off after a
period of inactivity.
Check that the “Auto Power Off” setting is not enabled.
Sound
The instrument is turned on, however
no sound is produced when the keys
are pressed.
Check that the MASTER VOLUME slider is not set to the lowest position.
Check that a pair of headphones (or headphone adaptor plug) are not
connected to the PHONES jacks.
Check that the SPEAKER ON/OFF switch (rear connectors) is not set to
Off.
Check that the Local Control setting in the MIDI Settings menu is set to
On.
The sound distorts when playing at
very loud volume levels.
Check that the MASTER VOLUME slider is set to an appropriate level,
reducing the volume if excessive distortion is heard.
Strange sounds or noises are heard
when playing with piano sounds.
The ES520 digital piano attempts to reproduce the rich variety of
tones created by an acoustic grand piano as accurately as possible.
This includes string resonances and damper noises, and other subtle
characteristics that contribute to the overall piano playing experience.
While these additional tones are intended to enhance the realism of
the instrument, it is possible to reduce their prominence, or disable the
effects altogether using the settings in the Virtual Technician menu.
–
The top 18 notes of the keyboard
sustain far longer than neighbouring
notes, even when the damper pedal is
not pressed.
This is the correct behaviour, and intended to reproduce the undamped
notes (typically the top two octaves) of an acoustic grand piano.
–
Phones
The headphone volume is too low.
Check the technical specifications of the headphones.
–
USB
A USB memory device is not detected,
cannot be saved to, or does not appear
to function when connected to the
“USB to Device” port.
Check that the USB memory device is formatted to use the FAT/FAT32
filesystem, and not set to “Write Protect” mode.
Disconnect the USB device, turn the instrument off then on, then
reconnect the USB device. If the USB device still does not function,
it may be damaged or incompatible. Please try using a different USB
device.
–
The instrument pauses briefly when
connecting a USB memory device.
This is recognised behaviour when using very large capacity USB
memory devices.
SMF
An SMF MIDI file stored on a USB
memory device sounds strange when
played back.
The ES520 digital piano does not contain the full General MIDI sound
bank selection. Consequently, some SMF song files may not be
reproduced entirely accurately when played through the instrument.
