6. Operating Instructions
6.1 Powering On/Off
Slide the power switch to the 'ON' position to power on the device. Slide it to 'OFF' to power off.
6.2 Self-Leveling Mode
When powered on, the laser level automatically enters self-leveling mode. If the device is placed on an uneven surface (beyond 4 degrees inclination), it will emit an audible warning and the laser lines will flash. Adjust the device's position until it is within the self-leveling range and the warning stops.
6.3 Manual Mode
To use the laser level for projecting angled lines, activate manual mode. This typically involves holding down a specific button (refer to the device's interface for exact button, often the 'Outdoor Mode' button) while powering on, or pressing a button after self-leveling is complete. In manual mode, the self-leveling function is deactivated, allowing the laser to project lines at any angle.

6.4 Line Selection
Use the 'H' button to toggle horizontal lines and the 'V' button to toggle vertical lines. The 4D system allows for various combinations, including 360-degree horizontal and vertical planes.
