AppAepndpixendix Troubleshooting Problem Power suddenly and unexpectedly turns off. When the instrument is turned on or off, a popping sound is temporarily produced. When using a mobile phone, noise is produced. There is no sound even when the keyboard is played or when a song or style is being played back. The style or song does not play back when the [START/STOP] button is pressed. The style does not sound properly. No rhythm accompaniment plays when the [START/STOP] button is pressed after selecting the BaroqueAir Style in the MOVIE & SHOW category. Not all of the voices seem to sound, or the sound seems to be cut off. The footswitch (for sustain) seems to produce the opposite effect. For example, pressing the footswitch cuts off the sound and releasing it sustains the sounds. The sound of the voice changes from note to note. The Demo display is shown in Japanese, and/or there are Japanese characters in the display messages. The ACMP indicator does not appear when the [ACMP] button is pressed. There is no harmony sound. The "OVER CURRENT" message is shown and the USB device does not respond. Possible Cause and Solution This is normal and the Auto Power Off function may have been activated (page 10). If desired, disable the Auto Power Off function. This is normal and indicates that the instrument is receiving electrical power. 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. Check that nothing is connected to the PHONES/OUTPUT jack on the rear panel. When a set of headphones is plugged into this jack, no sound is output. Is "Local Control" set to ON? Make sure "Local Control" is set to ON in the Function display. 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. Is "External Clock" set to OFF? Make sure "External Clock" is set to OFF in the Function display. Make sure that the "Style Volume" is set to an appropriate level in the Function display. Is the split point set at an appropriate key for the chords you are playing? Set the split point at an appropriate key in the Function display. Is the [ACMP] button lit? If it is not lit, press the [ACMP] button so it lights. This is not a malfunction. The BaroqueAir Style does not have a Rhythm part, so there is no rhythm sound for this Style. Also, this Style does not have a Fill-In section. The other parts will begin playing when you play a chord in the accompaniment. 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 "stolen") from the accompaniment or Song. The polarity of the footswitch is reversed. Make sure that the footswitch plug is properly connected to the SUSTAIN jack before turning on the power. This is normal. The AWM tone generation method uses multiple recordings (samples) of an instrument across the range of the keyboard; 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 12) Always press the desired style category button first when you are going to use any Style-related function. The Harmony effects (01-26) behave differently according to their type. Types 01-10 and 13 function when Style playback is on, chords are played in the accompaniment range of the keyboard, and a melody is played in the right-hand range. Types 15-26 will function whether Style playback is on or off. For types 23-26 you need to play two notes at the same time. Communication with the USB device has been shut down because of overcurrent to the USB device. Disconnect the device from the USB TO DEVICE terminal, then turn the power of the instrument off and on again. 64 Owner's Manual
