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.
2. Turn the lock knob clockwise to the “On” position to unlock the
compensator and allow the laser to self-level.
3. Place the laser on a relatively smooth, flat and level surface.
4. Set the lock knob to the “On” position.

sound.
