5.1 Transmitter (TX) Mode

In TX mode, the B310Pro transmits audio from a non-Bluetooth device (e.g., TV, PC) to Bluetooth-enabled headphones or speakers.

1. Slide the mode switch to "TX".
2. Connect your audio source (e.g., TV) to the B310Pro's input (Optical In or 3.5mm In).
3. Ensure your Bluetooth headphones/speakers are in pairing mode.
4. Press the Bluetooth button on the B310Pro for 2 seconds to enter pairing mode. The 'A' or 'B' indicator will flash.
5. Once connected, the corresponding indicator ('A' or 'B') will light up blue.

5.2 Receiver (RX) Mode

In RX mode, the B310Pro receives Bluetooth audio from your smartphone or tablet and outputs it to your wired home stereo system or speakers.

1. Slide the mode switch to "RX".
2. Connect your home stereo/speakers to the B310Pro's output (Optical Out or 3.5mm Out).
3. On your smartphone/tablet, search for Bluetooth devices and select "B310Pro" to connect.
4. Once connected, the 'RX' indicator will light up blue.

5.3 Bypass Mode

Bypass mode allows audio to pass through the B310Pro directly from your audio source to your wired speakers without Bluetooth transmission or reception. This is useful if you want to use your wired speakers and occasionally switch to Bluetooth headphones without re-cabling.

1. Slide the mode switch to "Bypass".
2. Connect your audio source (e.g., TV) to the B310Pro's input (Optical In or 3.5mm In).
3. Connect your wired speakers to the B310Pro's output (Optical Out or 3.5mm Out).
4. Ensure the 'Bypass' indicator is lit.

6. Pairing Instructions

Follow these steps to pair your Bluetooth devices with the 1Mii B310Pro in TX mode.

1. Ensure the B310Pro is in TX mode.
2. Put your first Bluetooth headphone/speaker into pairing mode.
3. Press the Bluetooth button on the B310Pro for 2 seconds. The 'A' indicator will flash, signifying it's searching for a device.
4. Once connected, the 'A' indicator will light up blue.
5. To pair a second device, put your second Bluetooth headphone/speaker into pairing mode.
6. Press the Bluetooth button on the B310Pro again for 2 seconds. The 'B' indicator will flash.
7. Once connected, the 'B' indicator will light up blue. Both 'A' and 'B' indicators will be lit, indicating two devices are connected.

7. Optical Audio Setup

When using the optical connection, ensure your TV's audio output settings are correctly configured.

2. On your TV, navigate to the Sound or Audio Settings menu.
3. Select "Audio Output" and choose "Optical" or "External Speakers".
4. Ensure the Digital Audio Format is set to "PCM" or "Stereo". Do not select Dolby Digital or DTS, as these formats are not supported by the B310Pro for optical input.
