4. Setup

4.1 Battery Installation

2. Open the cover and insert two AAA batteries, ensuring correct polarity (+/-).
3. Close the battery compartment cover securely.

4.2 Initial Power-On

1. Slide the pendulum lock switch to the unlocked position. This enables the self-leveling function.
2. Press the power button to turn on the device. The green laser cross lines will project.

5. Operating Instructions

5.1 Self-Leveling Mode

When the pendulum lock switch is in the unlocked position, the device will automatically self-level within an inclination of 4 degrees. If the device is placed on a surface exceeding 4 degrees, the laser lines will flash rapidly to indicate it is out of level. Adjust the device's position until the lines stop flashing and become steady.

5.2 Manual (Locked) Mode

To project laser lines at any angle, slide the pendulum lock switch to the locked position. The laser lines will be fixed, allowing for angled projections. In this mode, the self-leveling function is deactivated.

5.3 Brightness Adjustment

Press the brightness adjustment button (often integrated with the power button or a separate button) to cycle through the four brightness modes: 50%, 65%, 80%, and 100%. This allows you to optimize visibility based on ambient light conditions and conserve battery life.
