5. Setup

5.1 Powering the Transmitter

Connect the supplied USB power cable to the IN 5V (Micro USB) port on the transmitter.
Connect the other end of the USB cable to a USB power source. This can be a USB port on your TV, a USB wall adapter (not included), or any other standard 5V USB power supply.
The transmitter has an internal battery that provides up to 5 hours of use when not connected to a power source. The LED indicator will show charging status.

5.2 Connecting to an Audio Source

Choose one of the following methods to connect your audio source:

Using 3.5mm AUX (Analog Audio)

Ensure the transmitter is powered on.
Connect one end of the supplied 3.5mm AUX audio cable to the AUX IN port on the transmitter.
Connect the other end of the 3.5mm AUX audio cable to the audio output (headphone jack or AUX out) of your TV, Hi-Fi system, or other audio source.

Using Toslink (Digital Optical Audio)

Ensure the transmitter is powered on.
Connect one end of the supplied Toslink digital audio cable to the OPT-IN port on the transmitter.
Connect the other end of the Toslink cable to the digital optical audio output (usually labeled "Optical Out" or "Digital Audio Out") of your TV, Hi-Fi system, or other audio source.
Note: Ensure your audio source's digital audio output is set to PCM/Stereo format, not Dolby Digital or DTS, as these formats are generally not supported by stereo Bluetooth transmitters.

5.3 Pairing with Bluetooth Headphones/Speakers

Turn on the Meliconi Bluetooth Transmitter by pressing and holding the power button until the LED indicator starts flashing, indicating it is in pairing mode.
Place your Bluetooth headphones or speaker in pairing mode. Refer to your device's manual for specific instructions.
Keep the transmitter and your Bluetooth audio device close to each other (within 1 meter) during the pairing process.
The devices should automatically connect. Once successfully paired, the LED indicator on the transmitter will change to a solid light (or flash slowly, depending on the model's specific behavior).
Test the audio by playing content from your connected audio source.

6. Operating Instructions

6.1 Power On/Off

To Power On: Press and hold the power button for approximately 3 seconds until the LED indicator lights up.
To Power Off: Press and hold the power button for approximately 3 seconds until the LED indicator turns off.

6.2 Automatic Input Detection

The transmitter automatically detects the active audio input (AUX or Toslink). If both are connected, it typically prioritizes one or switches based on which one is actively sending a signal. No manual switching is usually required.

6.3 Reconnecting

Once paired, the transmitter will automatically attempt to reconnect to the last paired device when both are powered on and within range. If reconnection fails, manually put both devices into pairing mode again.

7. Maintenance

Cleaning: Wipe the device with a soft, dry cloth. Do not use liquid cleaners or abrasive materials.
Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures when not in use for extended periods.
Battery Care: For optimal battery life, avoid fully discharging the battery frequently. Charge the device regularly if using it wirelessly.

8. Troubleshooting

Problem	Possible Cause	Solution
No sound from headphones/speakers.	Transmitter not powered on. Not paired correctly. Incorrect audio input selected on source device. Volume too low on source or receiving device. Incorrect Toslink audio format (e.g., Dolby Digital instead of PCM). Cables not connected securely.	Ensure transmitter is powered on and charged. Re-pair the transmitter and Bluetooth device. Check audio output settings on your TV/source. Increase volume on both the source and the Bluetooth device. For Toslink, set TV audio output to PCM/Stereo. Verify all cables are firmly connected.
Cannot pair with Bluetooth device.	Transmitter not in pairing mode. Bluetooth device not in pairing mode. Devices too far apart. Interference from other devices.	Ensure transmitter LED is flashing (pairing mode). Put your Bluetooth headphones/speaker into pairing mode. Keep devices within 1 meter during pairing. Turn off other Bluetooth devices nearby.
Audio delay/latency.	Bluetooth codec limitations. Interference.	While Bluetooth 5.1 offers improvements, some latency can occur. Ensure no other devices are causing interference. Try moving closer to the transmitter.
Transmitter not charging.	Faulty USB cable or power source. Loose connection.	Try a different USB cable and/or power source. Ensure the USB cable is securely plugged into both the transmitter and the power source.
