Owner's Manual
Possible Cause and Solution
This is normal and indicates that the instrument is receiving electrical
power.
Using a mobile phone in close proximity to the instrument may pro-
duce interference. To prevent this, turn off the mobile phone or use it
further away from the instrument.
Check that nothing is connected to the [PHONES] jack on the bot-
tom. When a set of headphones is plugged into this jack, no sound is
output.
Check the Local Control on/off. (See page 105.)
Is the FILE CONTROL display showing? The instrument's keyboard,
etc., will not produce any sound while the FILE CONTROL display is
showing. Press the [EXIT] button to return to the MAIN display.
When using the Dictionary function (page 87), the keys in the right
hand area are used only for entering the chord root and type.
Is External Clock set to ON? Make sure External Clock is set to OFF;
refer to "External Clock" on page 105.
Make sure that the Style Volume (page 93) is set to an appropriate
level.
Is the split point set at an appropriate key for the chords you are play-
ing? Set the split point at an appropriate key (page 82).
Is the "ACMP" indicator showing in the display? If it is not showing
press the [ACMP ON/OFF] button so that it does show.
This is not a malfunction. Style number 131 and style numbers 143–
160 (Pianist) have no rhythm parts, so no rhythm will play. The other
parts will begin playing when you play a chord in the accompaniment
range of the keyboard if style playback is turned on.
The instrument is polyphonic up to a maximum of 64 notes. If the
Dual voice or Split voice is being used and a style or song is playing
back at the same time, some notes/sounds may be omitted (or "sto-
len") from the accompaniment or song.
The pedal cord may not be properly connected. Make sure securely
insert the pedal cord into the [PEDAL] jack (page 116).
This is normal. The AWM tone generation method uses multiple
recordings (samples) of an instrument across the range of the key-
board; thus, the actual sound of the voice may be slightly different
from note to note.
Make sure the Language setting in the FUNCTION display is set to
English. (See page 16)
Is another display showing? Try pressing the [EXIT] button to return
to the MAIN display, and then pressing one of the mentioned buttons.
