-
Set FM Frequency:
- Tune your car's FM radio to an unused, clear frequency (one with no static or broadcasting).
- Press the 'FM' button on the SUPERONE adapter. Use the 'Previous' and 'Next' track buttons to adjust the device's FM frequency to match your car radio's frequency.
- Ensure both frequencies match for optimal audio transmission.

3. Bluetooth Pairing:

- After the first successful pairing, the device will automatically connect to your phone when powered on.

Operating Instructions
Music Playback
- Via Bluetooth: Once paired, open your music application on your phone. Audio will transmit to your car's stereo via the set FM frequency. Use the 'Previous' and 'Next' track buttons on the adapter to control playback.
- Via USB Flash Drive: Insert a USB flash drive containing WMA, MP3, WAV, APE, or FLAC audio files into the designated USB port. The device will automatically detect and play music from the drive.
Hands-Free Calling
When a call comes in while connected via Bluetooth:
- Press the 'Answer' button (usually indicated by a phone icon) on the adapter to accept the call.
- Press the 'End' button to hang up.
- Press and hold the 'End' button to reject an incoming call.

Charging Devices
The adapter offers multiple charging options:
- Retractable PD 30W USB-C Cable: Pull out the USB-C cable to charge compatible Android devices or other USB-C devices at up to 30W.
- Retractable 12W Apple Cable: Pull out the Apple-compatible cable to charge iPhones or other Apple devices at up to 12W.
- 15W USB-C Port: Use your own USB-C cable to charge devices via this port.
- 12W USB-A Port: Use your own USB-A cable to charge devices via this port.


Troubleshooting
No Power / Device Not Turning On:Ensure the adapter is fully inserted into the car's power outlet. Check if the car's power outlet is functioning (e.g., by testing with another device). Some vehicles require the ignition to be on for the power outlet to be active.
Static Noise / Poor Audio Quality:Adjust the FM frequency on both the adapter and your car radio to a different, clear, unused frequency. Avoid frequencies used by local radio stations. Ensure the adapter is not placed near other electronic devices that might cause interference. If possible, try plugging the adapter into a different power outlet in the car (e.g., a rear outlet if available) as suggested by some users.
Bluetooth Connection Issues:Ensure Bluetooth is enabled on your smartphone. Delete 'PT-42' from your phone's paired devices list and attempt to re-pair. Restart both your phone and the car adapter (by unplugging and re-plugging it). Ensure no other Bluetooth devices are interfering with the connection.
Low Volume:Increase the volume on both your smartphone and your car's stereo system. Some users report that the volume for calls might be lower; adjust accordingly or use your phone directly for calls if necessary.
Charging Not Working:Check if the cables are fully extended and properly connected to your devices. Ensure your device is compatible with the charging port (e.g., USB-C for USB-C port). Verify that the car adapter is receiving power.
