5. Operating Instructions
5.1 Powering On and Self-Leveling
Press the power button on the Cubus G. The device will automatically self-level. The green laser technology provides excellent visibility for various applications.

Figure 5.1: The Cubus G 210S features Sensor Automatic and Auto Slope for precise leveling.
5.2 Operating Modes
The Cubus G 210S supports several operating modes:
- Rotation Mode: The laser rotates to create a continuous horizontal or vertical plane.
- Scan Mode: Creates a visible laser line in a specific adjustable angle.
- Point Mode: Projects a stationary laser point.
- Hand Receiver Mode: For use with the SensoLite G 210 laser receiver for extended range and outdoor applications.

5.4 Manual Slope Setting
The Cubus G 210S allows for manual setting of slopes. Refer to the device's interface or remote control for specific instructions on adjusting the tilt angle.
5.5 Remote Control Operation
The included remote control allows for convenient operation of all functions up to a maximum distance of 30 meters. This includes changing modes, adjusting scan angles, and activating specific features.
5.6 Tilt Warning Function (ADS Tilt)
The device is equipped with an ADS Tilt warning function. In case of external interference or significant movement, the laser will automatically shut down to prevent incorrect measurements. This ensures accuracy and reliability during operation.
