1. USB Charging: Connect the supplied USB Type-C cable to the Type-C Input port and a 5V DC power source. This is the fastest charging method.
2. Hand Crank Charging: Unfold the Crank Handle and rotate it clockwise or counter-clockwise at a steady pace (approximately 120-180 cycles per minute). This generates power to charge the internal battery.
3. Solar Charging: Place the radio with the Solar Panel facing direct sunlight. This method is ideal for maintaining charge or for slow charging in emergencies. Charging efficiency depends on sunlight intensity.

4.3 Flashlight and Reading Lamp

Press the Flashlight / SOS Button once to turn on the flashlight. Press again to switch to the LED reading lamp. Press a third time to turn off the light. The flashlight provides focused illumination, while the reading lamp offers broader, softer light.

5. Maintenance

5.1 Cleaning

Wipe the radio with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the surface. Ensure all ports are dry before charging or using the device.

5.2 Storage

Store the radio in a cool, dry place away from direct sunlight and extreme temperatures. If storing for an extended period, fully charge the battery every 3-6 months to maintain battery health.

6. Troubleshooting

• No Power: Ensure the radio is turned on. Check the battery level. If low, charge the radio using any of the three methods (USB, hand crank, solar).

• Flashlight/Lamp Not Working: Check battery level. Ensure the button is pressed correctly.
• External Device Not Charging: Ensure the radio has sufficient battery charge. Verify the USB cable connection. Some devices may require more power than the radio can provide.
