Setup Guide
Follow these steps to set up your FM transmitter:
- Find an Empty FM Frequency: Tune your car's FM radio to an empty frequency (one with no active radio station). Frequencies at the lower or upper end of the spectrum (e.g., around 87.5 MHz or 108.0 MHz) often work best.
- Plug in the Transmitter: Insert the SONRU FM transmitter into your car's 12V/24V cigarette lighter socket. The LED display will light up, showing the car battery voltage briefly, then the default FM frequency.
- Match FM Frequencies: Adjust the FM frequency on the transmitter to match the empty frequency you found on your car radio. To do this, press and hold the 'CH' (Multi-Function) button until the frequency on the display flashes. Then, rotate the 'CH' button left or right to adjust the frequency. Once matched, press the 'CH' button again to confirm.
- Pair via Bluetooth: On your smartphone or Bluetooth device, enable Bluetooth and search for available devices. Select 'T81' from the list to pair. Once connected, the display on the transmitter will stop flashing.
After the initial pairing, the transmitter will automatically connect to your device when Bluetooth is enabled on your phone and the transmitter is powered on.
