rotate 180 degrees internally and start auto-
leveling. The RC-300W will now display “X:2”.

the LS-70A laser sensor to locate the beam center.
Instead, note the beam location as shown on the

If adjustment is necessary proceed to the
“Adjusting” instructions below before checking the
remaining axis.
