5.2 Initial Charging

For optimal performance, fully charge the internal rechargeable battery before first use.

• USB Charging: Connect the provided USB cable to the DC 5V input port on the radio and to a USB power adapter (not included) or a computer USB port. The charging indicator light will illuminate.
• Solar Charging: Place the radio with its solar panel facing direct sunlight. The solar panel will convert sunlight into energy to charge the internal battery. This method is slower than USB charging and is best for maintaining charge or emergency situations.

6. Operating Instructions

6.1 Power On/Off and Volume Control

1. To power on the radio, rotate the Volume Knob clockwise from the "OFF" position.
2. Continue rotating the knob clockwise to increase the volume. Rotate counter-clockwise to decrease volume.
3. To power off, rotate the Volume Knob counter-clockwise until it clicks into the "OFF" position.

6.2 Radio Operation (AM/FM/SW)

1. Extend the Telescopic Antenna fully for optimal reception.
2. Use the Band Selector Switch to choose between FM, AM, or SW bands.
3. Rotate the Tuning Dial to scan for radio stations. The frequency display will indicate the current band and frequency.
4. Adjust the antenna position and radio orientation for the clearest signal.

7.1 Solar Charging

• Place the radio in direct sunlight with the solar panel facing upwards.
• The solar panel will automatically begin charging the internal 18650 battery.
• Solar charging is ideal for outdoor use and maintaining battery life, but it is slower than USB charging.

7.2 USB Charging

• Connect the small end of the provided USB cable to the DC 5V input port on the radio.
• Connect the standard USB end to a USB power adapter (e.g., phone charger, computer USB port, power bank).
• The charging indicator light will show the charging status.

7.3 D-Cell Battery Power (Alternative)

• In situations where the rechargeable battery is depleted and other charging methods are unavailable, you can power the radio using two D-cell alkaline batteries.
• Open the battery compartment and insert the D-cell batteries with correct polarity.
• Note: D-cell batteries are not rechargeable within the device. Remove them when not in use for extended periods.

8. Maintenance

• Cleaning: Wipe the radio with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Storage: Store the radio in a cool, dry place when not in use. If storing for a long period, ensure the rechargeable battery has some charge and consider removing D-cell batteries if used.
