This document describes the fine tuning features of digital pianos such as CLP-220, N-100, P-65, P-70, YDP-131/151/213/323/S30. It provides detailed instructions on how to raise or lower the pitch by adjusting the fine tuning, and provides the correct step units and setting range.
This correction sheet addresses errors in the instructions for raising or lowering the pitch. It clarifies that adjustments should be made in approximately 1 cent steps (where 100 cents equals one semitone), rather than the incorrect 0.2 Hz steps previously stated.
The document also corrects the setting range from the erroneous '4270-453.0 Hz' to '-65 to +65 cents'. It notes that the default setting is A3=440Hz, and in this region, 1 Hz corresponds to approximately 4 cents.
The correct step size is approximately 1 cent steps, not 0.2 Hz steps.
The correct setting range is -65 to +65 cents, replacing the incorrect 4270-453.0 Hz.
Pressing the key 8 times will set A3 at approximately 442Hz.
