TROUBLESHOOTING
Problems Possible Causes and Solutions
When the piano is turned on or
off, a popping sound is
temporarily produced.
This is normal and indicates that this
instrument is receiving electrical power.
When using a mobile phone,
noise is produced.
Using a mobile phone in close proximity to
the piano may produce interference.
To prevent this, turn off the mobile phone
or use it further away from the piano.
There is no sound even when
the keyboard is played or when a
song is being played back.
Check that nothing is connected to the
PHONES/OUTPUT jack on the rear panel.
When a set of headphones is plugged into
this jack, no sound is output.
The sound of the voices or
rhythms seems unusual or
strange
The battery power is too low. Replace the
batteries.
The accompaniment does not
sound properly. Make sure that the Accompaniment volume
is set to an appropriate level.
The voice chosen does not
sound properly, or the volume is
too low.
Make sure the settings are appropriate:
master volume, dual balance
Not all of the voices seem to
sound, or the sound seems to be
cut off.
The piano is polyphonic up to a maximum
of 64 notes. If the Dual voice is being used
and a style or song is playing back at the
same time, some notes/sounds may be
omitted (or stolen) from the
accompaniment or song.
The sound of a voice changes
from note to note.
This is normal. The AWM tone generation
method uses multiple recordings (samples)
of an instrument across the range o f the
keyboard; thus, the actual sound of the
voice may be slightly different from note to
note.
The foot switch (for sustain)
seems to produce the opposite
effect. For example, pressing the
foot switch cuts off the sound
and releasing it sustains the
sounds.
The polarity of the foot switch is reversed.
Make sure that the foot switch plug is
properly connected to the SUST AIN jack
before turning on the power.
