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 12).
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 the instrument. Turn off the mobile phone, or use it further away from the
instrument.
The Master Volume is set too low; set it to an appropriate level using the [MASTER
VOLUME] dial (page 14).
The volume level for the keyboard performance is set too low. Move the [SONG BALANCE]
slider toward "KEYBOARD" to increase the keyboard volume (page 40).
Headphones are connected when the Speaker setting is "Normal (HeadphoneSW)" (page
71). Disconnect the headphone plug.
Speaker setting is "Off." Set the Speaker to "Normal (HeadphoneSW)" or "On" (page 71).
Local Control is "Off." Set Local Control "On" (page 72).
"Expression" is assigned to the right pedal or the AUX pedal. Assign any function other
than "Expression" to the pedal (page 65).
Speaker setting is "On." Set the speaker setting to "Normal (HeadphoneSW)" (page 71).
The sound condition output from the internal speakers and the headphones changes
automatically to the appropriate settings depending on how the external device is
connected to the AUX OUT jacks. See chart on page 50.
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 85).
Some types of pedals may turn on and off in opposite fashion. Use the "AuxPedalType"
parameter (page 70) in the "FUNCTION" menu to change the external pedal setting.
The volume level for the keyboard performance is set too low. Move the [SONG BALANCE]
slider toward "KEYBOARD" to increase the keyboard volume (page 40).
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
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 mode or Split mode in the middle of the Song is not recorded. Also, the
recording part for the Voice 2 (Dual mode) or the left-hand Voice (Split mode) is
automatically assigned (page 40). If the assigned part already has data, the data will be
overwritten and deleted when you record.
The "CharacterCode" setting may be different than that is selected when you named the
Song. Also, if the Song was recorded on another instrument, the title might be displayed
incorrectly. Use the "CharacterCode" parameter (page 48) in the [FILE/SONG SETTING]
menu to change the setting. However, if the Song was recorded on another instrument,
changing the "CharacterCode" parameter setting may not resolve the problem.
