5.2. Mounting the Device
The LG-3Dx can be mounted using its integrated 1/4" thread or the included magnetic rotating stand.
- Magnetic Rotating Stand: Attach the laser level to the stand via the 1/4" thread. The stand's strong magnets allow it to be securely affixed to metal surfaces, providing flexible positioning.
- Tripod: For elevated or precise positioning, attach the laser level directly to any standard tripod with a 1/4" screw.
6. Operating Modes
The LG-3Dx Laser Level offers two primary operational modes: Self-Leveling and Manual.
6.1. Self-Leveling Mode
This mode automatically levels the laser lines, ensuring accuracy for tasks requiring perfectly horizontal or vertical alignment.
- Unlock the pendulum by sliding the pendulum lock switch to the unlocked position.
- Place the laser level on a relatively flat surface. The device will self-level within an inclination of 4 degrees.
- If the inclination exceeds 4 degrees, the laser lines will flash rapidly to indicate an out-of-level condition. Adjust the position of the device until the lines stabilize.
- Use the control panel buttons to select the desired laser planes (horizontal, vertical, or both).

6.2. Manual Mode
Manual mode allows you to project laser lines at any desired angle, useful for tasks like installing stair railings or decorative patterns.
- Lock the pendulum by sliding the pendulum lock switch to the locked position. This disables the self-leveling function.
- The laser lines will now be projected at the angle the device is positioned.
- Use the control panel buttons to select the desired laser planes.

6.3. Using the Remote Control
The included remote control enhances convenience, allowing you to operate the laser level from a distance.
- Ensure the laser level is powered on.
- Use the buttons on the remote control to switch between horizontal and vertical laser lines, or to power the device on/off.
- Refer to the remote control's specific button functions for detailed operation.
