Possible Cause and Solution
" This is normal and is no cause for alarm.
The R1/R2/L voice volume (Mixer) settings could be set too
low. Make sure the voice volumes are set at appropriate
levels.
Using a mobile phone in close proximity to the instrument
may produce interference. To prevent this, turn off the mobile
phone or use it further away from the instrument.
You may be trying to start accompaniment by playing a key
in the right-hand range of the keyboard. To start the
accompaniment with Sync Start, make sure to play a key in
the left-hand range of the keyboard.
Make sure that the tuning value is set to
hold the [+/YES] and [-/NO] buttons at the same time, then
turning the power on will set INSTRUMENT to default.
Harmony cannot be turned on when a drum kit is selected for
the voice R1.
Please check if the USB cable is being connected firmly, or
try to connect another USB port of the computer, without the
need to install another driver on the PC.
