3. Initial Setup
3.1 Charging the Radio
Before first use, it is recommended to fully charge the radio's internal 14800mWh (4000mAh) battery using the USB-C port.
- USB-C Charging: Connect the provided USB-C cable to the radio's USB-C input port and the other end to a standard USB power adapter (not included) or a computer USB port. The charging indicator will illuminate.
- Hand Crank Charging: Rotate the hand crank clockwise or counter-clockwise at a steady pace (approximately 130-150 RPM) for 3-5 minutes to generate sufficient power for initial operation or to extend battery life.
- Solar Panel Charging: Place the radio with the solar panel facing direct sunlight. This method is primarily for maintaining battery charge or for emergency power generation, and is slower than USB-C charging.

4. Operating Instructions
4.1 Powering On/Off and Volume Control
To power on the radio, rotate the Volume Knob clockwise from the 'OFF' position. Continue rotating to increase the volume. To power off, rotate the Volume Knob counter-clockwise until it clicks into the 'OFF' position.
4.2 Radio Tuning (AM/FM/NOAA)
- Extend Antenna: For optimal reception, fully extend the telescopic antenna.
- Select Band: Use the Band Selector switch to choose between 'AM', 'FM', or 'WB' (Weather Band).
- Tune Station: Rotate the Tuning Knob to scan for desired radio stations or NOAA weather channels. The tuning indicator light will illuminate when a strong signal is detected.

4.3 Flashlight Operation
The integrated flashlight offers multiple modes:
- Press the flashlight button once for Full Mode (maximum brightness).
- Press again for Far Mode (focused beam).
- Press a third time for Wide Mode (broader illumination).
- Press a fourth time to turn the flashlight off.

4.4 Reading Light Operation
The reading light provides illumination for close-range tasks:
- Slide the reading light switch to the 'LIGHT' position for constant illumination.
- Slide the switch to the 'AUTO' position to activate the motion sensor. The light will turn on when motion is detected and turn off after approximately 30 seconds of no motion.

4.5 SOS Alarm Function
In an emergency, activate the SOS alarm to attract attention:
- Press and hold the SOS Button to activate a loud siren and a flashing light.
- Release the button to deactivate the alarm.

4.6 Using as a Power Bank
The radio's internal battery can be used to charge external USB devices:
- Connect your smartphone, tablet, or other USB-powered device to the radio's USB-A Output Port using your device's charging cable.
- The radio will begin charging the connected device. Monitor the radio's battery indicator to ensure sufficient charge remains for its own operation.

5. Care and Maintenance
- Cleaning: Wipe the radio with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Storage: Store the radio in a cool, dry place away from direct sunlight and extreme temperatures. For long-term storage, ensure the battery is partially charged (around 50%) and recharge every 3-6 months to prevent deep discharge.
- Water Resistance: The radio is IPX3 water resistant, meaning it can withstand spraying water. Do not submerge the radio in water.

6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Radio does not turn on. | Battery is depleted. | Charge the radio via USB-C, hand crank, or solar panel. |
| Poor radio reception. | Antenna not extended, weak signal, interference. | Fully extend the telescopic antenna. Move to an open area away from obstructions. Fine-tune the tuning knob. |
| Flashlight/Reading light not working. | Battery is low, incorrect mode selected. | Charge the radio. Ensure the correct light mode (Full, Far, Wide for flashlight; Light, Auto for reading light) is selected. |
| External device not charging from radio. | Radio battery is low, cable issue, device incompatibility. | Ensure the radio has sufficient charge. Check the USB cable connection. Try a different USB cable or device. |
| Hand crank is stiff or difficult to turn. | Possible obstruction or internal issue. | Ensure there are no physical obstructions. Turn the crank smoothly and avoid excessive force. If problem persists, contact customer support. |
| Solar charging is slow or ineffective. | Insufficient sunlight, dirty solar panel. | Place the radio in direct, strong sunlight. Clean the solar panel surface with a soft cloth. Note that solar charging is supplementary. |
