Position the D-shaped cut of each sensor
(light-emitting and -sensing) as shown in the
Figure 1 below. Insert each sensor from the
bottom up to the step and provisionally fix it
with the "M2.5×8L" bolt (1) or (2).

Block the light by putting the jig plate
(with a filter) before the light-emitting
sensor (gray cable).
* Caution: If putting the plate before the
light-sensing sensor accidentally, the
glass will be broken.

Provisionally fix the block (A) of the light-
emitting sensor (gray cable) loosely
enough to move the block by hand.
Moving the block in the arrow directions,
find a point at which the amplifier level
reaches maximum and provisionally fix
the block.
