The amount of automatic shift is calculated according to ship’s speed, and the
amount of shift is limited to 50% of the range in use. For example, if you set the
shift speed setting for 15 knots and the ship is running at 10 knots the amount of
shift will be about 34%. The formula for determining shift amount is as shown
