5.2 Solar Charging

The integrated solar panel provides emergency charging when a wall outlet is unavailable. For daily use, wall charging is recommended for faster and more efficient power replenishment.

1. Place the solar panel directly under strong sunlight.
2. A green LED indicator will light up, indicating that solar charging is active.
3. Ensure the solar panel is clean and unobstructed for maximum efficiency.

Note: Solar charging is slower than wall charging and is primarily intended for emergency power maintenance rather than primary charging.
