11. Turn the tool off.
12. Insert the 2mm Allen wrench into the
front calibration port. Locate the
calibration screw and rotate it in a
clockwise direction to lower the beam
or in the counter-clockwise direction to
raise the beam.

13. Turn the tool on and check the position of
the beam to see if it is at a height exactly
halfway between the first and second
markings made on Surface 1 (where you
started). Repeat steps 11 to 13 until the
dot is halfway between the two markings.
14. Once this recalibration of the front beam
is complete, turn the tool off.
Replace the recalibration plug by
pressing it back firmly.
Calibrating the Top and Bottom Beams
15. Choose your recalibration site. To get the
most accurate calibration possible, it is
best to use a floor/ceiling distance
greater than 10' (the greater distance,
the better the accuracy). Floor/Ceiling
(top of doorway) distance of
approximately 10'.

16. Turn the tool off.
17. Remove the calibration plug on the side
of tool with a flathead screw-driver.
Set the plug where it will not be lost.
18. Draw a straight line on the ceiling.
19. Turn the tool on.
20. Place the tool on the floor (on its
accessory so that you can see the down
laser beam on the floor).

21. Align the tool so that the top laser
beam hits the line on the ceiling.
22. Mark the down laser beam on the floor,
Mark D. Mark the up laser beam on the
ceiling, Mark E.
23. Rotate the tool 180 degrees and align the
down beam with the mark on the floor.

24. Mark the up beam on the ceiling, Mark F.
You should have two marks on
the ceiling.
25. Compare the two marks on the ceiling. If
the two marks are on the same point, the
unit does not need to be calibrated. If the
two marks are not on the same point,
proceed to step 26.
26. Turn the tool off.
27. Insert the 2mm Allen wrench into the side
calibration port. The objective is to get
the laser beam halfway between the two
marks on the ceiling. Turn the Allen
wrench clockwise or counter clockwise to
move the laser beam.
28. Turn the tool on and check the
position of the beam to see if it is exactly
halfway between the marks on the
ceiling. If the beam is not correctly
positioned, repeat steps 26–28 until the
beam is at the correct position.
29. Plug the side calibration plug on
the tool.
30. Calibration is complete.
