- Built-in Rechargeable Battery: The radio includes a 4000mAh Lithium-Ion battery. To use, ensure the power switch is set to 'LI-ION'.
- D-size Batteries: For extended use or as a backup, you can insert four (4) D-size batteries (not included) into the battery compartment on the rear of the radio. Ensure correct polarity. Set the power switch to 'BATT' to use D-size batteries.
3.2 Charging the Built-in Battery
To charge the built-in battery:
- Connect the provided Type-C charging cable to the radio's Type-C charging port.
- Connect the other end of the cable to a USB power adapter (5V/1A recommended, not included) or a computer's USB port.
- The LCD screen will indicate charging status. A red LED indicator will also illuminate if the radio is off during charging.
- Charging is complete when the battery indicator shows full or the red LED turns off.
Note: It is recommended to fully charge the battery before first use. Presets may be lost if the internal battery completely drains or if D-batteries are removed without the internal battery being charged.
4. Operating Instructions
4.1 Power On/Off and Volume
- Turn the POWER knob clockwise to power on the radio. Select 'LI-ION' for the internal battery or 'BATT' for D-size batteries.

5. Maintenance
- Cleaning: Use a soft, dry cloth to clean the radio's exterior. Do not use abrasive cleaners or solvents.
- Battery Care: If using D-size batteries, remove them if the radio will not be used for an extended period to prevent leakage. For the built-in Lithium-Ion battery, charge it regularly to maintain its lifespan, even if not in frequent use.
- Storage: Store the radio in a cool, dry place away from direct sunlight and extreme temperatures.
- Antenna: Handle the telescopic antenna carefully to avoid bending or breaking. Retract it when not in use.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Radio does not power on | Low battery (internal or D-cells); Power switch in wrong position. | Charge the built-in battery or replace D-size batteries. Ensure power switch is set to 'LI-ION' or 'BATT' correctly. |
| Poor radio reception | Antenna not extended; Weak signal; Interference. | Fully extend the telescopic antenna. Try repositioning the radio or rotating it for AM. Move away from electronic devices causing interference. |
| Sound distortion at high volume | Volume too high; Tone setting. | Reduce the volume. Adjust the TONE switch (Low/High) to find a clearer sound profile. |
| MP3s not playing from USB/TF | Incorrect file format; Media not inserted correctly; Radio not in MP3 mode. | Ensure files are in MP3 format. Reinsert USB drive/TF card. Press MODE to select MP3 playback. |
| Presets are lost | Internal battery completely drained. | Keep the internal battery charged. Presets are generally preserved when switching between D-batteries and internal battery if the internal battery has some charge. |
