The CONENTOOL laser level offers multiple placement options for versatility:
- Direct Placement: Place the unit on a stable, flat surface.
- Tripod Mounting: The unit is threaded compatible with most tripods. Attach the laser level to the 1m tripod (if included) using the conversion screw if necessary. Adjust the tripod legs and vertical height adjustment handle for desired elevation.
- Wall Magnetic Bracket: Use the wall magnetic bracket to attach the laser level to metallic surfaces for precise height adjustment.
- Lifting Base: Utilize the plastic or all-aluminum lifting platform for convenient and fine height adjustments on flat surfaces.
- 360° Rotating Base: The mini tripod or semi-aluminum fine-tuning base allows for precise 360° rotation and adjustment.


4. Operating Instructions
4.1. Powering On and Self-Leveling
- Standard Start (Self-Leveling Mode): Slide the power switch to the 'ON' position. The device will automatically self-level within ±3°. If the tilt exceeds 3°, an alarm will sound, and the laser lines will flash to indicate it's out of range.
- Manual Mode (without alarm): To operate in manual mode (e.g., for angled lines), press and hold the 'H' or 'V' button to start the device without the self-leveling alarm. The laser lines will remain active even if the device is tilted beyond 3°.

4.2. Laser Line Selection and Modes
The laser level provides 16 lines (4 horizontal, 12 vertical) for comprehensive coverage. You can select specific lines or modes:
- Horizontal Lines (H): Press the 'H' button to cycle through horizontal laser lines.
- Vertical Lines (V): Press the 'V' button to cycle through vertical laser lines.
- Pulse Mode: Activate pulse mode for use with a laser receiver (not included) in bright conditions or over longer distances.
- Flash Mode: Use flash mode for specific applications as needed.


4.3. Brightness Adjustment
The laser level features 5-stage adjustable brightness for optimal visibility in different lighting conditions. Long press the 'H' button to increase brightness and long press the 'V' button to decrease brightness. This allows for up to 13 hours of operating time depending on the brightness setting and battery capacity.

4.4. 360° Rotatable Windows
The laser line windows can be rotated 360° to prevent broken laser lines and ensure continuous projection around obstacles. This feature enhances flexibility and accuracy in complex environments.

4.5. Remote Control Operation
Use the included remote control device to conveniently switch laser lines and modes from a distance, improving efficiency and ease of use.
5. Maintenance
- Cleaning: Regularly clean the laser windows and the device body with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Storage: When not in use, store the laser level and its accessories in the provided cloth bag or plastic box in a dry, cool place, away from direct sunlight and extreme temperatures.
- Battery Care: Remove batteries if the device will not be used for an extended period. Recharge batteries periodically to maintain their lifespan.
- Calibration: While the device features automatic leveling, if you suspect a calibration issue or notice consistent inaccuracies, refer to the full user manual for calibration procedures or contact customer support.
