6. Operating Modes
The LG-3Dx offers two primary operating modes: Self-Leveling Mode and Manual Mode.
6.1 Self-Leveling Mode
- Slide the pendulum lock switch to the unlocked position.
- The laser level will automatically self-level within an inclination of ±4°.
- If the device is outside this range, the laser lines will flash rapidly to indicate it cannot self-level. Adjust the device's position until the lines stabilize.
- Press the H button to activate/deactivate horizontal lines.
- Press the V1/V2 button to activate/deactivate vertical lines.
6.2 Manual Mode (Tilt Mode)
- Slide the pendulum lock switch to the locked position.
- The laser lines can now be projected at any desired angle without self-leveling.
- The laser lines will flash slowly to indicate that manual mode is active and the lines are not level.
- Press the H button to activate/deactivate horizontal lines.
- Press the V1/V2 button to activate/deactivate vertical lines.

6.3 Pulse Mode
- Activate Pulse Mode by pressing the dedicated pulse button (often indicated by a 'P' or wave icon) on the device or remote control.
- In Pulse Mode, the laser beam's intensity is modulated, allowing it to be detected by a compatible laser receiver (not included) over longer distances or in bright conditions.
- The working range can be extended up to 328 feet (100 meters) with a receiver.

9. Maintenance
- Clean the laser level regularly with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Keep the laser apertures clean to ensure clear beam projection.

- Avoid exposing the device to extreme temperatures or direct sunlight for prolonged periods.
- Ensure the pendulum lock is engaged during transport to prevent damage to the internal components.
10. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Laser lines are flashing rapidly. | Device is out of self-leveling range (±4°). | Place the device on a more level surface or adjust its position until the lines stabilize. |
| Laser lines are flashing slowly. | Manual mode is active. | This is normal behavior for manual mode. If self-leveling is desired, unlock the pendulum. |
| Laser lines are dim or not visible. | Low battery, bright ambient light, or dirty laser apertures. | Charge the battery. Use in a less brightly lit environment or activate Pulse Mode with a receiver. Clean laser apertures. |
| Remote control not working. | Remote battery depleted or obstruction between remote and device. | Replace remote control battery. Ensure clear line of sight. |
