Possible Cause and Solution
This is normal and is no cause for alarm.
Make sure the master volume is 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.
