The screen will display the battery status during charging.
2. Antenna Connection
The radio comes with two types of antennas: a telescopic antenna and a circle antenna.
- Telescopic Antenna: Suitable for general FM and VHF reception. Screw the telescopic antenna onto the SMA-KE connector on the top of the radio. Extend it fully for optimal reception.
- Circle Antenna: Ideal for improved reception on AM, Shortwave (SW), and HF bands. Screw the circle antenna onto the SMA-KE connector. Position it away from metallic objects for best performance.
Operating Instructions

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Radio does not power on. | Low battery; power button not pressed long enough. | Charge the radio fully. Press and hold the power button for 3-5 seconds. |
| Poor reception. | Antenna not connected or extended; interference; weak signal. | Ensure antenna is properly connected and extended. Try repositioning the radio or using the appropriate antenna (telescopic for FM/VHF, circle for AM/SW/HF). Move away from electronic devices causing interference. The Hi-Z circuit improves weak signal resolution. |
| No sound from speaker/headphones. | Volume too low; headphones not fully inserted; faulty headphones. | Increase volume. Ensure headphones are fully plugged into the 3.5mm audio jack. Test with different headphones. |
