4. Installation
4.1 Chargement de la batterie
The FRL300R is powered by a rechargeable Li-ion battery. Before first use, fully charge the battery. Connect the provided charging cable to the Type-C charging port on the laser level and plug the 5V/1A adapter into a power outlet. A full charge provides up to 15 hours of working time.

Figure 3: The FRL300R supports multiple charging methods via its Type-C port.
4.2 Initial Placement and Mounting
Place the FRL300R on a stable, level surface or mount it securely onto a tripod. Ensure the area is clear of obstructions that might interfere with the laser beam. The unit is designed with a robust 4-handle ergonomic design for easy handling.

5. Mode d'emploi
5.1 Mise sous tension et autonivellement
Press the power button to turn on the FRL300R. The unit features electronic horizontal self-leveling, automatically leveling itself within 5° in approximately 15 seconds. If the device is disturbed during operation, it will automatically re-level. The self-leveling motors are accurate to ±10 seconds.

5.2 Réglage de la vitesse de rotation et de l'angle de balayage
The FRL300R offers variable rotation speeds (0-300-600rpm) and scanning angle options (0°-10°-45°-90°-180°-0°). Use the controls on the unit or the remote control to adjust these settings according to your application needs.

Figure 6: The remote control allows for convenient adjustment of laser settings.
5.3 Vibrate Mode
For use in windy or vibrating conditions, activate the vibrate mode. In this mode, the self-leveling function is deactivated, and the laser cross is locked, allowing the device to be used at any angle without constant re-leveling due to minor disturbances.
5.4 Utilisation du récepteur
The included laser receiver extends the working range and improves visibility in bright conditions. It can be used in a handheld position or mounted on a rod using the provided clamp. The receiver is IP55 waterproof and dustproof, ensuring reliable performance in various environments.

7. Dépannage
If you encounter issues with your FRL300R, refer to the following common problems and solutions:
| Problème | Cause possible | Solution |
|---|---|---|
| Le laser ne s'allume pas | Batterie faible ou épuisée | Charge the Li-ion battery fully. |
| Le laser ne se nivelle pas automatiquement. | Unit is outside of ±5° self-leveling range | Place the unit on a more level surface or adjust tripod. |
| Lectures inexactes | Unit disturbed during operation; Calibration needed | Allow unit to re-level; If persistent, contact support for calibration. |
| Faisceau laser non visible | Too much ambient light; Long distance | Use the laser receiver; Use red laser glasses; Work in lower light conditions if possible. |
