7. Operating Modes
Self-Leveling Mode
This mode automatically levels the laser lines within a ±3° range.
- Push the side switch to the unlocked position (unlocked icon).
- The laser level will automatically self-level. If the tilt exceeds 3°, an audible alarm will sound, and the laser lines will flash.
- Place the laser level on a flat, stable surface until the alarm stops and the lines become steady.
Manual Mode (Tilt Mode)
This mode allows you to project laser lines at any desired angle.
- Ensure the side switch is in the locked position (locked icon).
- Touch the power on/off icon on the touch panel to activate manual mode.
- The laser lines will project without self-leveling, allowing for angled projections without an alarm.

11. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Laser lines are flashing and beeping in self-leveling mode. | The device is tilted beyond its ±3° self-leveling range. | Place the laser level on a flatter, more stable surface. |
| Laser does not turn on. | Battery is low or not installed correctly. | Charge the battery or ensure it is properly inserted. |
| Laser lines are dim or not visible. | High ambient light or brightness setting is too low. | Adjust brightness using the touch panel/remote. Use in lower light conditions or with a laser detector for outdoor use. |
| Remote control not working. | Remote battery is dead or out of range. | Replace remote battery. Ensure you are within the 160ft operating range. |
