1. Introduction
Thank you for choosing the Geevorks 4D 16-Line Laser Level. This device is designed to provide precise horizontal and vertical alignment for various construction, renovation, and interior decoration tasks. Please read this manual thoroughly before operation to ensure safe and efficient use of the product.
2. Product Overview and Features
The Geevorks 4D 16-Line Laser Level offers advanced features for enhanced accuracy and versatility:
- 4D 16 Lines: Emits 16 laser lines, individually or simultaneously, for precise positioning. Features a 3° auto-leveling system for flexibility and stability. High-quality laser diodes and precision conical mirrors ensure fine, bright, and highly accurate laser lines with adjustable brightness.
- Automatic Leveling (±3°): Equipped with a self-test calibration function. Auto-levels within ±3°. If the angle exceeds 3°, the laser light will flash and an audible alarm will sound, indicating the need to reposition the device on a level surface.
- Remote Control & App Connectivity: Includes a remote control for easy operation (H for vertical lines, V for horizontal lines). Brightness can be adjusted using '+' or '-' buttons. Scan the QR code on the remote to download the mobile app for Bluetooth control, offering adjustable brightness and voice control.
- Multi-functional Design: Press the 'OUT' button for 3 seconds to activate tilt mode, allowing projection of lines at any angle. Short press 'OUT' or long press 'H' or 'V' buttons to adjust laser brightness according to working conditions.
- Value-Added Accessories: Includes a T-shaped wall mount with 7mm wall distance, featuring a 360° rotating base and fine-tuning mechanism for quick target acquisition (1/4-inch screw size). A 1/4-inch to 5/8-inch thread adapter allows use with 5/8-inch tripods for height adjustment. Also includes a laser level lifting support.

5. Operating Instructions
5.1 Power On/Off
To power on the device, slide the main switch to the 'ON' position. The laser lines will activate, and the device will begin auto-leveling. To power off, slide the main switch to the 'OFF' position.
5.2 Auto-Leveling Mode
When powered on, the laser level automatically enters auto-leveling mode. If the device is within ±3° of level, the laser lines will stabilize. If the tilt angle exceeds 3°, the laser lines will flash continuously, and an audible alarm will sound. Reposition the device on a flatter surface until the lines stabilize and the alarm stops.

5.3 Manual Tilt Mode
To project lines at an angle (e.g., for stair railings), activate the manual tilt mode:
- With the device powered on, press and hold the 'OUT' button for 3 seconds.
- The laser lines will stop flashing, indicating that manual tilt mode is active. The auto-leveling function is now disabled.
- You can now position the laser level at any desired angle to project inclined lines.
- To exit manual tilt mode, press and hold the 'OUT' button again for 3 seconds, or power cycle the device.
5.4 Line Selection and Brightness Adjustment
Use the 'H' and 'V' buttons on the control panel or remote control to select horizontal and vertical laser lines. Pressing 'H' activates/deactivates horizontal lines, and 'V' activates/deactivates vertical lines. To adjust brightness, use the '+' or '-' buttons on the remote control, or short press the 'OUT' button or long press 'H' or 'V' buttons on the device.

8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Laser lines are flashing and device is beeping in auto-leveling mode. | The device is tilted beyond its ±3° auto-leveling range. | Reposition the laser level on a more level surface until the lines stabilize and the alarm stops. |
| Laser lines are dim or not visible. | Low battery, high ambient light, or brightness setting is too low. | Charge the battery. Use the device in lower light conditions if possible. Adjust brightness using the remote or device buttons. |
| Remote control or app not responding. | Remote battery low, device not in range, or Bluetooth not connected. | Replace remote battery. Ensure device is within Bluetooth range. Re-establish Bluetooth connection via the app. |
