Possible Cause and Solution
This is normal and the Auto Power Off function may have been activated
(page 15). If desired, disable the Auto Power Off function.
The plugs are not properly connected. Make sure that the DC plug is
securely inserted into the DC IN jack on the instrument, and that the AC
plug is securely inserted to the AC outlet (page 14).
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 smart
device, we recommend that you set "Airplane Mode" to "ON" on your smart
device in order to avoid noise caused by communication. While Bluetooth
is connected, setting "Airplane Mode" to "ON" disconnects Bluetooth;
however, the connection can be restored by reconnecting again.
The Master Volume is set too low. Set it to an appropriate level using the
[MASTER VOLUME] knob (page 11).
Make sure a pair of headphones or conversion adaptor is not connected to
the [PHONES] jack (page 15).
The Speaker setting is "Off." Set the Speaker to "Normal" or "On" (page 15).
Make sure that Local Control is On. For details, refer to the "MIDI
Reference" (page 9).
The pedal cord may not be securely connected to the [TO PEDAL] jack. Be
sure to insert the pedal cord all the way until the metal part of the cord plug
disappears from view (pages 36, 39).
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.
