3.2 Alternative Power Sources

Figure 3.1: The three versatile charging methods for the Raddy RE40: Hand Crank, Solar Panel, and USB-C.
- Hand Crank Charging: Extend the hand crank from the side of the radio. Rotate the crank clockwise or counter-clockwise at a steady pace (approximately 130-150 RPM) for 3-5 minutes to generate sufficient power for short-term use or emergency calls.
