The main lights are positioned away from the camera and angled outward to minimize glare. A close-up light, located next to the camera, helps reduce shadows but should be turned off in large dusty areas to prevent blinding effects. To manage lighting effectively, pilots can choose between **automatic mode**, where the close-up light activates within 90 cm of a surface, and **manual mode**, which requires full control over light operation. Proper use of these settings improves visibility and performance in challenging conditions. {% embed url="" %} *** ### **Battery temperature management for optimal performance** Maintaining batteries within the ideal **20-25°C range** is crucial for performance, especially in extreme climates. A built-in temperature sensor alerts users if the battery falls below **10°C** or exceeds **40°C**, with monitoring available in the Cockpit app. For **cold climates**, store batteries in an insulated box, use a battery discharger for gradual warming, or place a hot water bottle inside. In **warm climates**, cooling can be achieved with a frozen water bottle wrapped in a towel. Proper temperature management ensures battery efficiency and longevity. {% embed url="" %} *** ### Drone Safety Precautions: Handling and Protective Measures Spinning propellers pose a safety risk, but the **ELIOS drone’s protective cage** minimizes danger, allowing safer handling. To avoid injuries, **wear gloves** and hold the drone cage **with flat hands**. Regularly inspect the **cage for damage**, as broken parts can have sharp edges and compromise protection. Following these safety guidelines ensures both user and drone safety during operation. {% embed url="" %} *** ### **ELIOS 2 Stabilization System: Sensors, Control Modes, and Best Practices** The **ELIOS 2 stabilization system** allows precise hovering using **optical and distance sensors** instead of GPS. These sensors measure movement and distance but can be affected by **dust, direct sunlight, and dark or reflective surfaces**. The default **ASSIST Mode** stabilizes the drone, but in **dusty or featureless environments**, the system may fail, requiring a switch to **Attitude Mode** for manual control. Pilots should **clean sensors after each flight, practice Attitude Mode, and plan routes near textured surfaces** for optimal stability. {% embed url="" %} *** ### **Propellers Maintenance: Inspection and Replacement** The **ELIOS drone propellers** spin at up to **30,000 RPM**, designed to deform upon impact, they can suffer **wear from dust and dents from debris**, leading to **increased drag, vibrations, and motor strain**. To maintain performance, **inspect propellers before every flight** and **replace them if deformations exceed 1mm**. {% embed url="" %} *** ### **Enhancing Comfort for Optimal Drone Operation** Pilots need **full focus** when flying indoor inspection drones. However, **industrial settings** can be uncomfortable, with **standing positions and screen reflections** affecting visibility and concentration. To improve focus and reduce fatigue, pilots should **bring a chair for comfort, use an umbrella to eliminate screen glare, and sit to maintain a stable posture**. A relaxed position ensures better control, minimizing errors and enhancing inspection efficiency. {% embed url="" %}
