The sound of the Voices or rhythms seems unusual or strange. The display has gone out and the panel settings have been returned to default. The battery power is too low. Replace all batteries with new ones of the same type. (See page 3.) Not all notes are heard when playing a number of notes simultaneously. Too many keys are pressed at the same time. The PortaTone is polyphonic up to a maximum of 28 notes. (See page 42.) There is no sound when the keyboard is played. The Local Control setting could be off. Make sure Local Control is turned on. (See page 40.) The Auto Accompaniment does not function properly. Chords played in the lower section of the keyboard do not sound or sound different than expected. Make sure that you're playing in the Auto Accompaniment section of the keyboard. (See page 22.) Also, make sure that you're using the proper Fingering mode and that you're playing "legal" chords that the PortaTone can recognize. For example, when playing Single Finger chords, make sure that the Single Finger mode is selected. (See page 26.) There is no sound even when the keyboard is played or when a Song is being played back. Check that nothing is connected to the PHONES/AUX OUT jack on the rear panel. When a set of headphones is plugged into this jack, no sound is output. The selected Voice does not sound properly. Make sure that the following settings are appropriate: Main Voice Volume (page 11), Dual Voice Volume (page 13), and Split Voice Volume (page 15) The selected Accompaniment Style or Song does not sound properly. Make sure that the Accompaniment Volume or Song Volume is set to an appropriate level. (See pages 23, 32.) Split Point 2 cannot be entered, or the Accompaniment Split Point cannot be entered.
