8. D-Beam Adjustment test
This adjusts the sensitivity of the [D BEAM] controller.
This adjustment sets the optimal sensitivity for the controller by making
adjustments for two distances from the [D BEAM] controller; at 5 cm and at 45 cm.
Before you begin this test: The location of the Fantom must satisfy the
following conditions.
Do not place objects nearby the Fantom. (It must be at least 30 cm from

Place the Fantom at a distance from large flat surfaces such as ceiling or walls.
(It must be at least 100 cm away from such surfaces.)
Do not place the Fantom where strong light, such as direct sunlight or electric
light, can fall on it.
When you enter the D-Beam Adjustment test, the LCD display will show as
follows.
