5. Bedriuwsinstruksjes
5.1 Powering On and Self-Leveling
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 Adjusting Rotation Speed and Scanning Angle
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 De ûntfanger brûke
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.
