5.2. Inserting the Battery
- Ensure the power ON/OFF switch on the side of the unit is in the "OFF" (locked) position.
- Locate the battery compartment.
- Insert the charged Li-ion battery, ensuring correct polarity.
- Close the battery compartment securely.
6. Operating Instructions
6.1. Power ON/OFF and Mode Selection
The laser level features a main power ON/OFF switch on the side and separate buttons for line mode selection on the top panel.
- Side Switch (Power ON/OFF):
- Slide the switch to the "UNLOCKED" position to power on the device and activate Self-Leveling Mode.
- Slide the switch to the "LOCKED" position to power off the device. This position also enables Manual Mode when the device is powered on via the top button.
- Top Buttons (Line Selection):
- The "H" button controls the horizontal laser line. Press to toggle it on/off.
- The "V" button controls the vertical laser lines. Press to toggle them on/off.
- The Power Symbol button (circle with vertical bar) is used to activate Manual Mode when the side switch is in the "LOCKED" position. Press and hold for 2 seconds to enter/exit Manual Mode.

6.2. Self-Leveling Mode
- Place the laser level on a stable surface within ±3° of true level.
- Slide the side power switch to the "UNLOCKED" position.
- The laser level will automatically self-level. Once level, the laser lines will emit steadily.
- If the device is outside its self-leveling range (more than ±3° tilt), the laser lines will flash and an audible alarm will sound. Adjust the position of the laser level until it is within range and the lines become steady.
- Use the "H" and "V" buttons to select the desired horizontal and/or vertical lines.

6.3. Manual Mode (Locked Mode)
Manual mode allows you to project laser lines at any desired angle, useful for tasks like installing handrails or decorative elements on a slope.
- Slide the side power switch to the "LOCKED" position.
- Press and hold the Power Symbol button on the top panel for approximately 2 seconds. The laser lines will activate and remain locked at the current angle. The lines will not flash or beep in this mode, regardless of tilt.
- Adjust the physical angle of the laser level as needed.
- Use the "H" and "V" buttons to select the desired horizontal and/or vertical lines.
- To exit Manual Mode, press and hold the Power Symbol button again for 2 seconds, or slide the side switch to the "UNLOCKED" position to return to self-leveling mode.

10. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Laser lines are flashing and beeping in Self-Leveling Mode. | The device is tilted beyond its self-leveling range (±3°). | Adjust the position of the laser level to be within ±3° of true level. |
| Laser lines do not turn on. | Battery is low or not inserted correctly; device is off. | Ensure battery is charged and correctly inserted. Slide the side switch to "UNLOCKED" for self-leveling mode or activate Manual Mode correctly. |
| Laser lines are dim or not visible outdoors. | Bright ambient light conditions. | Green lasers are generally more visible than red, but extreme sunlight can still affect visibility. Use a laser receiver (not included) for outdoor use over long distances or in very bright conditions. |
| Laser lines are not straight or accurate. | Device is not properly calibrated or is damaged. | If in Self-Leveling Mode, ensure the device is within its ±3° range. If the issue persists, contact customer support. Do not attempt to recalibrate or repair yourself. |
