Possible Cause and Solution
This is normal and no cause for alarm.
Check if the master volume is set too low or if headphones are
plugged into Jack 2.
Using a mobile phone in close proximity to the instrument may
produce interference. To prevent this, turn off the mobile phone or
keep it away from the instrument when using.
