Troubleshooting
Problem
The speakers produce a pop sound 
whenever the power is turned ON or OFF.
No sound when the keyboard is played.
When using a mobile phone, noise is
produced.
The auto accompaniment does not play 
back even Sync is in standby condition 
and a key is pressed.
Certain notes sound at wrong pitch.
The Harmony function does not operate.
Possible Cause and Solution
This is normal and is no cause for alarm.
Make sure the master volume is set to an appropriate level. Check if headphones 
are plugged into the PHONES/OUTPUT jack. 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 righthand 
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 0. Press and hold the [+/YES] and
 [-/NO] buttons at the same time, then turning the power on will set 
INSTRUMENT to default.
Please make sure the Harmony function is on. And Harmony cannot be turned on 
when a drum kit is selected for the voice R1.
Notice:
If you notice any abnormality that cannot be handled, please connect the provider or specified repair agent, 
and have the instrument inspected by qualified service personnel.
