5. Operating Instructions

5.1. Radio Mode

1. Power On: Move the Function Switch (2) to the "RADIO" position.
2. Select Band: Use the Band Switch (8) to select your desired band (FM, AM, or SW).
3. Adjust Volume: Rotate the Volume Adjust (6) knob to set the desired listening volume.
4. Tune Station: Slowly rotate the Selection Button (5) (Tuning Knob) to find your preferred station. The radio broadcast sound will become clear when the station signal is strong enough.
5. Optimize Reception:
   • For FM or SW broadcasts, pull out the Telescoping Antenna (4) and rotate it to achieve the best reception. The antenna extends up to 48cm.
   • For MW (AM) broadcasts, rotate the radio body's angle to obtain the best reception effect.

1. Power On: Move the Function Switch (2) to the "MP3" position.
2. Insert TF Card: Ensure a TF card with MP3 audio files is inserted into the TF Card Slot (3).
3. Control Playback: Use the MP3 Play Key (4) and other related buttons (if present) to play, pause, skip tracks, or fast forward/rewind. The radio supports breakpoint memory, meaning it will resume playback from where it left off.

5.3. Bluetooth Mode

The XHDATA D-328 supports Bluetooth connectivity. To use Bluetooth:

1. Power On: Move the Function Switch (2) to the "MP3" position. (Bluetooth is typically activated in MP3 mode or a dedicated Bluetooth mode if available, though the manual doesn't specify a separate switch for Bluetooth).
2. Pairing: On your external device (e.g., smartphone), enable Bluetooth and search for available devices. Select "XHDATA D-328" or a similar name to pair.
3. Playback: Once paired, audio from your external device will play through the radio's speaker.

6. Charging the Battery

When the sound becomes much quieter, audibly distorted, MP3 playback restarts repeatedly, or the unit turns off automatically, it indicates that the battery is low and needs immediate charging.

1. Connect Charger: Use the provided USB charging cable and connect it to the DC 5V/500mA jack (1) on the radio. Connect the other end to a compatible USB power adapter (5V / at least 500mA or 1A).
2. Charging Indicator: The charging LED indicator will light up during charging. It will turn off once the battery is fully charged.
3. Charging Time: A full charge typically takes 6 to 8 hours. A charger with higher amperage (e.g., 1A) may charge the battery faster.
4. Battery Care: If the unit will not be used for a long time, remove the lithium battery from the compartment, store it separately, and recharge it at least once every two months to ensure its longevity.
5. Safety Precaution: Ensure the battery is not inserted reversely to prevent damage to the battery and extend its service life.

8. Troubleshooting

• No Power / Unit Turns Off: If the unit has no power or turns off automatically, the battery is likely low. Recharge the battery immediately.
• Poor Radio Reception:
  • For FM/SW, fully extend and rotate the telescoping antenna for optimal signal.
  • For AM (MW), rotate the entire radio body to find the best reception angle.
• MP3 Playback Issues: If MP3 playback restarts repeatedly or sound is distorted, the battery may be low. Ensure the TF card is properly inserted and contains valid MP3 files.
• Charging Problems: If the radio does not charge, try using a different USB power adapter. Some chargers (e.g., high-wattage ones) might not be compatible, while lower-wattage chargers (e.g., 25W) may work without issues. Ensure the charger provides 5V/500mA or 1A.
• Mono Sound: The radio's speaker is mono. Even through headphones, the audio output is mono (both channels played through each side without separation). This is a characteristic of the device, not a fault.

9. User Tips

• FM Reception: The FM band generally receives well, even with the antenna closed in urban areas.
• Shortwave Listening: Shortwave (SW) stations are often best received at night.
• Battery Authenticity: Be aware that there are many counterfeit BL-5C batteries on the market. Ensure you use a genuine or high-quality replacement battery to avoid issues.
• Cleaning: The glossy plastic body can easily show fingerprints and dirt, so regular cleaning is recommended.
• No Presets: This radio uses mechanical tuning and does not feature digital station presets.
