The Laser Beams Flash
When in self-leveling mode, the lasers are designed
to self-level up to an average of 4° in all directions. If
the laser is tilted so much that the internal mechanism
cannot level itself (or the laser is not level when in
manual mode), the laser beams will flash indicating
that the tilt range has been exceeded.
THE FLASHING BEAMS CREATED BY THE LASER
ARE NOT LEVEL OR PLUMB AND SHOULD NOT BE
USED FOR DETERMINING OR MARKING LEVEL
OR PLUMB. Try repositioning the laser on a more
level surface.
Laser Beams Will Not Stop Moving
The laser is a precision instrument. Therefore, if it is
not positioned on a stable (and motionless) surface,
the laser will continue to try to find level. If the beam
will not stop moving, try placing the laser on a more
stable surface. Also, try to make sure that the surface
is relatively flat and level, so that the laser is stable.
