- USB Charging: Connect a standard Micro USB cable (not included) to the Micro USB Input Port on the radio and to a USB power adapter (not included) or computer USB port. The CHARGE indicator will illuminate during charging.
- Solar Charging: Place the radio with the solar panel facing direct sunlight. This method is primarily for maintaining charge or slow charging in emergencies. The CHARGE indicator will illuminate.
- Hand Crank Charging: Rotate the hand crank clockwise or counter-clockwise at a steady pace (approximately 120-150 RPM) for 3-5 minutes to generate power. The CHARGE indicator will illuminate.
Note: For initial use, it is recommended to fully charge the internal battery via USB.
2. AA Batteries
For an alternative power source, you can use 3 AA batteries (not included).
- Locate the battery compartment on the back of the unit.
- Open the compartment and insert 3 AA batteries, observing the correct polarity (+/-).
- Close the battery compartment securely.
- Set the Battery Selector Switch to "AA".
Important: Do not attempt to charge AA batteries using the radio's charging methods. Remove AA batteries if the unit will not be used for an extended period.
