9. Remove the Allen wrench from the calibration port. Turn on the power, turn
on the level laser beam, then check the height of the laser beam. Repeat
steps 7 and 8 until the beam is at a height exactly halfway between A and B.
# Caution: The Allen wrench must be removed from the calibration port
before turning on the power.
10. Mark this calibrated point on the vertical surface, as C.
11. Repeat steps 3-7 to confirm the position of C, then proceed to step 12.
12. Rotate the base unit 90° and position it with the front facing the vertical sur
face. Mark the height of the laser beam, as D.
13. Compare the height of D with C. If the height of D matches the height of C,
calibration is complete. Turn the power switch to the off position. Reattach
the calibration port covers, then resume normal operation. If the height of D
does not match the height of C, proceed to step 14.
14. Turn off the laser beam and power to the unit.
# Caution: The laser beam must be turned off and the power switch in the
off position before proceeding to the next step.
15. Insert an Allen wrench into the front calibration port and locate the calibration
screw. Rotate it clockwise to lower the beam, or counterclockwise to raise
the beam.
