Troubleshooting

Q When the instrument is turned on or off, a popping sound is temporarily
produced.
A
This is normal and indicates that the instrument is receiving electrical power.
Q When using a mobile phone, noise is produced.
A
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.
Q Noise is heard from the instrument's speakers or headphones when
using the instrument with your smart device, such as an iPhone/iPad.
A
When you use the instrument along with the application on your smart device,
we recommend that you set that device's "Airplane Mode" to "ON" and then the
Bluetooth setting to "ON" on your smart device in order to avoid noise caused by
communication.
Q No sound is produced even when the keyboard is played, or a Song is
being played back.
A
Check whether a set of headphones is connected to the [PHONES], or not. When
such a connection is made, no sound is output from the speaker of this instrument.
A
Check the on/off status of Local Control (page 4). Normally, set this parameter to
ON.
Q Not all of the Voices seem to sound.
Q The sound seems to be cut off when playing the keyboard or Song.
A
You have exceeded 48 simultaneous notes, which is the maximum polyphony (the
maximum amount of notes that can be played simultaneously) of this instrument. If
the Voices are being used along with playback of Song, some notes/sounds may be
omitted (or "stolen").
Q Sound input via the [TO HOST] jack isn't produced from the built-in
speaker of the instrument, or it is too low.
A
Check that the volume setting is not too low on your smart device.
