3.1.6 Positioning by the joystick
 This instrument is designed to perform measurement in Auto mode
to ensure higher accuracy through standard operation. However,
Auto Alignment may not be particularly effective when insufficient
light is reflected due to deformation or inflammation of the cornea. In
this case, conduct measurement manually.
 The reflection in the center of the cornea may not be clearly viewed
when the deformation and/or inflammation of the cornea is severe. In
this case, an error may occur even in Manual mode.
There are two types of operations - rough operation for roughly positioning the
measuring head and fine operation for finely adjusting the position of the measuring
head.
[Rough operation]
Moving the joystick moves the measuring head back, forth, left, and right. When the
up/down ring is slid up and down, the head moves up and down. (Fig. 1)
[Fine operation]
Tilting the joystick moves the measuring head in the tilting direction.
Turn the up/down ring to move the head up and down. (Fig. 2)
(Fig. 1) (Fig. 2)
Clockwise …………… The head rises.
Counterclockwise… ..The head lowers.
