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 14).
This is normal when electrical current is being applied to the instrument.
This is normal and due to the Auto Power Off function. If necessary, set the parameter of the Auto Power Off
function (page 90).
Communication with the USB device has been shut down because of the overcurrent to the USB device.
Disconnect the device from the USB [TO DEVICE] terminal, then turn on the power of the instrument.
The noise may be due to interference caused by the use of a mobile phone in close proximity to the instrument.
Turn off the mobile phone, or use it further away from the instrument.
When you use the instrument along with the application on your iPhone/iPad, we recommend that you set that
device's "Airplane Mode" to "ON" and then the Wi-Fi setting to "ON" on your iPhone/iPad in order to avoid noise
caused by communication.
The Master Volume is set too low; set it to an appropriate level using the [MASTER VOLUME] slider (page 17).
The volume level for the keyboard performance is set too low. Adjust the volume balance to increase the
keyboard volume via the "Song" menu display: "Volume"  "Song - Keyboard" (page 45).
Headphones are connected when the Speaker setting is "Normal" (page 90). Disconnect the headphone plug.
The Speaker setting is "Off." Set the Speaker to "Normal" via the "System" menu display: "Utility"  "Speaker"
(page 90).
Local Control is "Off." Set Local Control "On" via the "System" menu display: "MIDI"  "Local Control" (page 89).
"Expression" is assigned to the right pedal. Assign any function other than "Expression" to the pedal (page 80)
via the "Voice" menu display: "Pedal Assign"  "Right" (page 80).
The Speaker setting is "On." Set the speaker setting to "Normal" via the "System" menu display: "Utility" 
"Speaker" (page 90).
The pedal cord may not be securely connected to the [PEDAL] jack. Be sure to insert the pedal cord all the way
until the metal part of the cord plug disappears from view (page 104).
The volume level for the keyboard performance is set too low. Adjust the volume balance to increase the
keyboard volume via the "Song" menu display: "Volume"  "Song - Keyboard" (page 45).
While you are using a function, some buttons not used for the function are disabled. If the Song is playing, stop
playback. Otherwise, press the [EXIT] button to return to the Voice or Song display, Then, perform the desired
operation.
This instrument can cover the range of C -2 – G8 when you set the transposition or octave. If notes lower than C
-2 are played, the sound is moved one octave higher. If notes higher than G8 are played, the sound is moved
one octave lower.
Switching to Dual/Split/Duo mode in the middle of the Song is not recorded. Also, the recording part for the Voice
2 (Dual mode) or the left Voice (Split/Duo mode) is automatically assigned (page 52). If the assigned part
already has data, the data will be overwritten and deleted when you record.
This is because the default pan setting differs depending on the Voice.
Change the settings from the "Voice" menu  "Voice Edit"  "Voice name"  "Pan" (page 79).
If the song cannot be read, you may need to change the character for the Song name. For information about the
character types available for the Song name, refer to "Character List" (page 91).
When Song is being played back, menu display other than "Voice" menu and "Song" menu will not appear. Stop
the Song by pressing the [R/K] (Play/Pause) button. Also, in the recording ready mode, only "Recording" menu
display will appear.
