Setup Instructions

Follow these steps for initial setup and pairing:

1. Insert the Adapter: Plug the LIHAN Bluetooth Car Adapter into your vehicle's 12V-24V cigarette lighter socket. The LED display will light up, indicating power.
2. Find a Blank FM Frequency: Tune your car's FM radio to an empty frequency (one with no active broadcast). This frequency should produce static or silence to minimize interference.
   

   This image illustrates the first step of setup, showing a car radio display tuned to a blank FM frequency, such as 103.9 MHz, to minimize interference.
3. Set Adapter FM Frequency: Press and hold the "CH/EQ" button on the adapter until the FM frequency on the LED display starts flashing. Rotate the multi-function knob (rotate button) to match the adapter's frequency to the blank FM frequency you found on your car radio. Once matched, press the "CH/EQ" button again to confirm.
   

   This image demonstrates the second step, where the adapter's LED display shows 103.9 MHz, matching the car radio's blank frequency. The adapter's frequency is flashing, indicating it's ready for adjustment.

4. Pair with Bluetooth: On your mobile device, enable Bluetooth and search for available devices. Select "HY-66" (or a similar name) from the list to pair. A voice prompt will confirm successful connection. You will not need to repeat pairing after the first successful connection.

Maintenance

• Ensure the cigarette lighter socket is free of debris before inserting the adapter.

Troubleshooting

No Power / Device Not Turning On

• Ensure the adapter is fully inserted into the cigarette lighter socket.
• Check your car's cigarette lighter fuse. If blown, replace it according to your vehicle's manual.
• Verify your vehicle's power outlet is functioning correctly by testing it with another device.

Static or Poor Audio Quality

• Ensure the FM frequency on both the adapter and your car radio are identical and set to a blank frequency (one with no active broadcast).
• Try a different blank FM frequency if interference persists, especially in urban areas.
• Adjust the volume on both your car radio and the adapter. Setting the adapter's volume too high can cause distortion.
• Ensure your mobile device's volume is also at an appropriate level.
• Move your mobile device closer to the adapter to improve Bluetooth signal strength.

Bluetooth Connection Issues

• Make sure Bluetooth is enabled on your mobile device.
• Forget the device "HY-66" from your mobile device's Bluetooth settings and attempt to pair again.
• Restart both your mobile device and the car adapter (by unplugging and re-plugging it).
• Ensure no other devices are actively connected to the adapter, as it supports one Bluetooth connection at a time.

Charging Not Working

• Verify that the charging cable is securely connected to both the adapter and your device.
• Check if your charging cable is damaged. Try a different, known-good cable.
• Ensure your device supports fast charging for QC3.0 or PD ports to utilize the full charging speed.
