3.2 Initial Placement and Mounting

Place the laser level on a stable, flat surface. For optimal performance, ensure the surface is within the self-leveling range (±3°). The unit can be placed directly on the floor, on the mini tripod, or on the lifting base for height adjustment. For wall applications, use the magnetic bracket with the upper wall iron plate.

4. Operating Modes

4.1 Self-Leveling Mode

In self-leveling mode, the laser level automatically levels itself within a range of ±3°. If the surface inclination exceeds this range, the device will sound an alarm and the laser lines will flash continuously, indicating that it is out of level. Adjust the position of the laser level until it self-levels.

4.2 Manual/Tilt Mode

To activate manual mode, long-press the brightness key on the control panel for 3 seconds. In this mode, the self-leveling function is disabled, allowing the device to be used at any angle. This is useful for projecting oblique lines, such as for staircase installations or decorative patterns.

The remote control allows for convenient switching between horizontal and vertical lines, as well as adjusting brightness levels without directly touching the unit.
