• To restore factory settings (and clear all previous pairings), long-press the "search" button for 8 seconds.
• When pairing AirPods for the first time, ensure they are inside their case.
• For optimal pairing, turn off nearby Bluetooth devices (e.g., phones, iPads) during the pairing process.

Maintenance

To ensure the longevity and optimal performance of your PROW A5 Pro, follow these maintenance guidelines:

• Keep the device dry. Moisture and liquids can damage internal circuits.
• Do not expose the device to extreme temperatures (hot or cold).

   Ensure the toggle switch is firmly set to the desired mode position (RX or TX).
3. Audio quality is not optimal or low-quality:
   First, check your audio source device. For reduced latency and higher quality, ensure your device supports Bluetooth 5.2 and aptX-LL codecs.
