3. Setup
3.1 Battery Installation and Charging
The device comes with a rechargeable 12.6V/2600mAh Li-ion battery. Ensure the battery is fully charged before first use. Connect the power adapter to the laser level and a power outlet using the provided Type-C cord. The LCD screen will indicate charging status.
3.2 Mounting the Laser Level
The Huepar W04CG-4D can be mounted in various ways for optimal use:
- On a Flat Surface: Place the laser level directly on a stable, flat surface.
- Using the Lifting Base: For precise height adjustments, place the laser level on the included lifting base. This allows raising the beam from 1" to 3.54" above ground.
- Magnetic Bracket: Attach the magnetic bracket to the back of the laser level. Use the strong magnets to secure the device to metal surfaces or the included steel sheet.
- Tripod Mounting: The laser level features 1/4"-20 and 5/8"-11 mounting threads for compatibility with standard tripods.

4. Operating Modes
The Huepar W04CG-4D offers versatile operating modes to suit various applications:
4.1 Self-Leveling Mode
This mode automatically levels the laser lines within a ±3° range. If the device is outside this range, it will emit an audible alarm and the laser lines will flash. To activate, unlock the pendulum by sliding the pendulum lock to the unlocked position. The laser will self-level within 4 seconds.
4.2 Manual Mode (Tilt Mode)
For projecting lines at any angle, engage the manual mode. Lock the pendulum by sliding the pendulum lock to the locked position. Press the 'H' or 'V' button to activate horizontal or vertical lines. The laser lines will remain active without self-leveling, allowing for custom angle projections.
4.3 Pulse Mode
When working in bright conditions or over long distances (up to 200ft), activate pulse mode. This mode allows the laser level to be used with a Huepar laser receiver (sold separately) to extend the working range and improve visibility. Press the pulse mode button on the device or via the app/remote to enable.

4.4 Bluetooth and Remote Control
The integrated electric rotating base can be controlled via Bluetooth using a mobile app or with the included remote control from up to 65ft away. This allows for quick targeting and fine-tuning of the laser lines without manually adjusting the device. The app also allows for adjustable visibility levels (Level 1, 2, 3).

6. Maintenance
Proper maintenance ensures the longevity and accuracy of your Huepar laser level:
- Cleaning: Use a soft, damp cloth to clean the device. Do not use abrasive cleaners or solvents. Keep the laser windows clean for optimal beam clarity.
- Storage: Store the laser level in its hard carry case in a dry, cool place when not in use. Ensure the pendulum is locked before storage or transport to prevent damage.
- Battery Care: For long-term storage, charge the battery to approximately 50% and recharge every 3-6 months to maintain battery health.
- Calibration Check: Periodically check the calibration of your laser level according to the instructions in the full user manual (PDF link provided in product details) to ensure continued accuracy.
7. Troubleshooting
If you encounter issues with your Huepar laser level, refer to the following common troubleshooting steps:
- Laser Not Turning On: Check if the battery is properly installed and charged. Ensure the power switch is in the ON position.
- Laser Lines Flashing/Beeping: This indicates the device is outside its self-leveling range. Place the laser level on a more level surface or manually adjust its position until the alarm stops and lines stabilize.
- Weak or Invisible Laser Lines: Ensure the laser windows are clean. If in pulse mode, ensure a compatible laser receiver is being used. In bright outdoor conditions, a receiver is often necessary.
- Bluetooth Connection Issues: Ensure Bluetooth is enabled on your mobile device and the laser level. Try restarting both devices. Refer to the app's instructions for pairing.
- Remote Control Not Responding: Check the remote control's battery. Ensure there are no obstructions between the remote and the laser level.
