CHECKING THE 90° ANGLES
•
Place the instrument 5 m from two walls at an
angle
•
Turn the laser on by pressing the ON/OFF button
twice. Mark off point A on the floor.
•
Mark off point B on the wall at a height of 1 m.
and then point C at the same height on the other
wall.
•
Rotate the instrument over point A until the line
from point B crosses point C.
•
Mark off point D on the wall near point B at a
height of 1 m.
•
If point B and D are more than 3 mm apart, the
instrument should be calibrated.
If you find that the laser is out of align-
ment, return the unit to your retailer to
be recalibrated at an authorised service
centre.
