Manual vs. Self-leveling Operation
1. Turn the lock knob counter-clockwise to the “Off” position to lock
the compensator. The laser will be operating in manual mode and
will not be self-leveling.

function properly. If the laser is tilted to exceed its self-leveling
range, it will stop rotating and will sound an intermittent beeping
sound.
Leveling the Laser for use in Vertical Mode
(Bubble Level Adjustment)
1. Turn the lock knob counter-clockwise to the
“Off” position to lock the compensator. The
laser will be operating in manual mode and will
