PRUNUS Manuals & User Guides

PRUNUS is a consumer electronics brand dedicated to blending classic design with modern audio technology. Operated by Jin Ming Technology Co., Ltd., the brand is best known for its extensive range of portable radios that offer high quality reception and user-friendly features. Their product lineup caters to diverse needs, ranging from nostalgic wooden desktop radios that integrate Bluetooth and MP3 playback to rugged, battery-operated handheld units designed for simplicity and seniors.

In addition to lifestyle audio, PRUNUS is a key player in the emergency preparedness market. Their disaster prevention radios are equipped with essential survival tools such as NOAA weather alerts, hand-crank generators, solar panels, and SOS alarms. Whether providing daily entertainment through AM/FM/SW broadcasts or ensuring connectivity during power outages, PRUNUS devices are built with powerful DSP chips and long antennas to ensure reliable signal performance in various environments.

• How do I improve the radio reception on my PRUNUS device?

  Adjust the telescopic antenna's length and direction for FM/SW bands. For AM reception, rotate the radio itself as the internal magnetic antenna is directional. Place the device near a window and away from interference sources like computers, TVs, and wall chargers.

• How do I charge my PRUNUS emergency radio?

  Most PRUNUS emergency radios support USB charging (the primary method), solar charging (for battery maintenance), and hand-crank charging (for emergencies). Some models also accept standard AA/AAA batteries as a backup power source.

• Why is my TF/MicroSD card not working with the radio?

  Ensure your card is formatted to FAT or FAT32, as many radios cannot read NTFS. Also, check that the music files are in a supported format like MP3, WMA, or WAV, and that the card capacity does not exceed the model's limit (often 32GB or 64GB).

• How do I pair my content via Bluetooth?

  Switch the radio to Bluetooth mode using the Mode button. The indicator should blink or a tone will sound. On your mobile device, search for the radio's name (e.g., 'J-160' or 'PRUNUS') and tap to connect.
