4. Operation

4.1 Tuning and Reception

To achieve the best reception:

1. Extend the Antenna: Fully extend the 16.5-inch telescopic antenna for FM and Shortwave reception. For AM, the radio uses a built-in ferrite bar antenna, so antenna extension is not necessary.
2. Select Band: Use the band selector switch to choose FM, AM, or one of the SW (SW1-SW7) bands.
3. Tune to a Station: Slowly rotate the tuning knob until you hear a clear broadcast. The frequency display will help you identify stations. Note that the analog tuning may require patience for precise station locking.
4. Adjust Antenna Position: For optimal FM and SW reception, try adjusting the angle and direction of the telescopic antenna. For AM, rotate the entire radio for better signal strength.

4.2 Audio Output

The PRUNUS J-711 delivers clear audio through its integrated speaker. For private listening, plug any standard 3.5mm headphones into the earphone jack located on the side of the radio. The internal speaker will automatically mute when headphones are connected.

4.3 Portability

Designed for convenience, the PRUNUS J-711 is lightweight and compact, making it easy to carry anywhere. Use the included wrist strap to secure the radio to your hand or hang it. The fold-out stand provides stable placement on flat surfaces.

5. Maintenance

To ensure the longevity and optimal performance of your PRUNUS J-711 radio, follow these maintenance guidelines:

• Cleaning: Wipe the radio with a soft, dry cloth. Do not use abrasive cleaners, waxes, or solvents as they may damage the finish.
