Problem
Meaning
Possible Cause and Solution
The instrument has not been plugged in properly. Securely insert the female
plug into the socket on the instrument, and the male plug into a proper AC
outlet (page 13).
This is normal when electrical current is being applied to the instrument.
The noise may be due to interference caused by the use of a mobile phone in
close proximity to this instrument. Turn off the mobile phone, or move it
further away from this instrument
When you use the instrument along with the application on your iPhone/
iPad, we recommend that you set "Airplane Mode" to "ON" on your iPhone/
iPad in order to avoid noise caused by communication.
The volume is set too low. Set it to an appropriate level using the [VOLUME]
slider (page 14).
Make sure a pair of headphones is not connected to the headphones jack
(page 13).
Make sure that Local Control is On (page 34).
The damper pedal was pressed when the power was turned on. This is not a
malfunction; release the pedal and press it again to reset the function.
The output volume of the external device connected to this instrument is too
low, resulting in the sound being cut off via the Noise Gate after it is input to
this instrument.
• Increase the output volume of the external device. The volume level
reproduced via this instrument's speakers can be adjusted by using the
[VOLUME] slider.
• Set the Noise Gate to off (page 33).
Refer to the Message List (page 37) in case a message is displayed. If this
happens without any messages, the USB flash memory may be damaged.
