on/off power
There was no sound when you pressed
keyboard on power state.
The note and its tone quality of a same
tone are a little different.
When use the sustain function,some
tone has long sustain but some has
short sustain.
The master volume is too small, or the
volume of voice and accompaniment
are imbalance.
There is still no accompaniment even
though sync starting had been started
and keyboard was played.
The pitch of note is not correct.
The notes that were pressed down at
the same time,but,there aren't all
notes that can sound.The auto
accompanime nt function sees to be
jumped out of as long as you play the
keyboard.
The sound distorted or discontinued,
even,halted when you use external
power adator.
There is no sound for external soundbox
amplifier.
Possible causes/resolution
Do not worry, it's the normal
phenomenon.
Check whether the master volume
button was set at proper position or
headphone out jack was connected with
other equipment so the built-in speaker
system cutted off automatically.
This is normal phenomenon caused by
different tone sampling system of
electronic keyboard.
This is normal phenomenon because the
best length of the sustain of the
different tone has been set.
Check the main volume control and the
accompaniment volume control are set
at the proper position.
Please check that chord way was setted
at relative chord position, you only have
to play the keyboard that lies in auto
bass chord area, then,the
accompaniment can start.
Check whether the parameter of
transpose is "00".
You may used excessive notes,their
quantity had surpassed the maximum
quantity that was set in electronic
keyboard.so,the extra more notes can't
sound.
Because unqualified power adaptor had
been used,please use the power adaptor
that was equipped with this keyboard.
Please check whether master volume
was adjusted too low,or the connection
line has the mistake.
