×
17" white paper. (Be careful to draw precisely parallel
lines.)
(2) Set the adjustment original made in (1) as shown below.

Adjustment procedure (1)
When La>Lb (Lc
frame side of the No. 4/5 mirror base unit.
When LaLd): Rotate to decrease the height of the front
frame side of the No. 4/5 mirror base unit.
Open the front cabinet, insert a screwdriver
as shown below, and turn the eccentric
screw to adjust the height of the No. 4/5
mirror base.
When turning the eccentric screw, remember how much it
is rotated from the original position. When the eccentric
screw is turned 36 degrees, the height of the front frame
side of the No. 4/5 mirror base is increased or decreased
by 2mm and the difference (La – Lb) is varied by 4mm.
If the above adjustment is not effective, then follow
the Adjustment procedure (2) .
Adjustment procedure (2)
1 Move the mirror base rail B up and down in the arrow directions
to adjust.
• When La > Lb, shift the mirror base B rail upward by half of
the difference of La – Lb.
• When La < Lb, shift the mirror base B rail downward by half of
the difference of La – Lb.
