6. Operating Instructions
6.1 Power On/Off
To power on the device, slide the side switch to the 'ON' position. To power off, slide the switch to the 'OFF' position.
6.2 Self-Leveling Mode
When the side switch is in the 'ON' position, the device enters self-leveling mode. The laser will automatically level itself within a ±3° range. If the device is placed on a surface that is not within this range, the laser lines will flash rapidly and an audible alarm will sound, indicating that the device is out of level. Adjust the position of the laser level until the lines stop flashing and the alarm ceases.

6.3 Manual Mode
To activate manual mode, ensure the side switch is in the 'OFF' position. Then, press and hold the power button on the top of the device for 3 seconds. In manual mode, the pendulum is locked, allowing you to project laser lines at any desired angle for sloped applications. The laser lines will not self-level in this mode.

6.4 Line Selection
The laser level features separate buttons for controlling horizontal and vertical lines. Press the 'H' button to activate or deactivate the horizontal line. Press the 'V' button to activate or deactivate the vertical lines. You can use these buttons to select specific lines or combinations of lines as needed for your task.
