Troubleshooting
Problem
When the PortaTone is turned on or off, a buzzing
sound is temporarily produced.
The sound of the voices or rhythms seems unusual
or strange.
Possible Cause and Solution
This is normal and indicates that power is flowing
into the PortaTone.
The battery power is too low. Replace the batteries.
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 12
notes. (See the note on page 5.)
The sound of the Voice changes from note to note.
The power cannot be turned on.
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.
Quick, successive pressing of the POWER ON/OFF
button may fail to turn the power on. When using
the POWER ON/OFF button, wait a short time be-
tween successive presses.
