5. Setup
- Charging the Battery: Before first use, fully charge the lithium battery using the provided charger. Insert the battery into the designated compartment on the laser level.
- Placement: Place the laser level on a stable, level surface. For height adjustments, use the included lifting frame. For wall mounting, attach the wall magnet mounting bracket to a suitable surface and then secure the laser level to the bracket.
- Power On: Slide the main power switch to the 'ON' position. The laser level will emit green lines and begin its self-leveling process.
- Self-Leveling: The device will automatically self-level within an inclination of ±4°. If the device is placed on a surface that is too uneven (beyond ±4°), it will emit a beep alarm and the laser lines will blink every 3 seconds, indicating it cannot self-level. Adjust the position until the alarm stops and the lines become stable.

6. Operating Instructions
- Turning On/Off: Use the main power switch located on the side of the unit to turn the device on or off.
- Mode Selection (Smart Touch): The device features 'Smart Touch' buttons for controlling laser lines and modes.
- 'H' Button: Activates/deactivates horizontal laser lines.
- 'V' Button: Activates/deactivates vertical laser lines.
- Tilt Mode: To use the laser level at an angle (e.g., for stairs), press and hold the 'H' or 'V' button (or a dedicated tilt button if present) to lock the pendulum. The laser lines will then be projected at a fixed angle without self-leveling, and may blink slowly to indicate tilt mode.
- Remote Control: The included remote control allows for convenient operation from up to 10 meters away. Use the buttons on the remote to switch between horizontal and vertical lines, or to activate tilt mode.
- APP Remote Control: For advanced control, scan the QR code on the back of the laser level to download the dedicated mobile application. Turn on the laser level's Bluetooth switch (if available) and connect via the app to control functions remotely.

7. Maintenance
- Cleaning: Regularly clean the laser level with a soft, dry cloth. Do not use abrasive cleaners or solvents. Keep the laser apertures clean to ensure clear beam projection.
- Storage: When not in use, store the laser level in its cloth box in a dry, cool place, away from direct sunlight and extreme temperatures.
- Battery Care: Remove the battery if the device will not be used for an extended period. Recharge the battery periodically to maintain its lifespan.
- Calibration: If you suspect the laser level is out of calibration, refer to the troubleshooting section or contact customer support. Do not attempt to self-calibrate without proper instructions.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Laser lines are blinking and/or device is beeping. | Device is out of its self-leveling range (inclination > ±4°). | Place the laser level on a more level surface until the alarm stops and lines stabilize. |
| No laser lines are projected. | Device is not powered on, battery is low/dead, or laser lines are turned off. | Ensure the power switch is ON. Check battery charge and recharge if necessary. Press 'H' or 'V' buttons to activate lines. |
| Remote control is not working. | Remote battery is dead, or device is out of range. | Replace remote battery. Ensure you are within 10 meters of the device. |
| Laser lines appear dim or unclear. | Dirty laser apertures, or operating in very bright conditions. | Clean laser apertures with a soft cloth. Use in appropriate lighting conditions. |
| Device shakes excessively before settling. | Initial settling of the pendulum, or unstable surface. | Allow a few seconds for the pendulum to settle. Ensure the device is on a stable surface. |
9. User Tips
- Beam Quality: Users have noted that the laser lines are smooth and do not flash when switching brightness, indicating good beam stability.
- Horizontal Line Adjustment: The horizontal lines are fixed relative to each other. The overall height of the horizontal plane can be adjusted using the lifting frame or by repositioning the unit.
- Beam Visibility: While specific beam thickness at distance is not provided, the green laser offers superior visibility compared to red lasers, making it suitable for both indoor and outdoor use.
- APP Control: Utilize the APP remote control feature for greater convenience, especially when the laser level is placed in hard-to-reach areas.
