5.3 Mode Switching

The LE523 supports three working modes: CIS (Bluetooth Audio Receiver), BIS (Bluetooth Broadcast Transmitter), and RX (Bluetooth Broadcast Receiver). To switch between modes, click the 'Mode Key'. The indicator lights will change to reflect the active mode.

6. Operating Modes

The LE523 offers three distinct operating modes to suit various audio transmission and reception needs.

6.1 CIS Mode (Bluetooth Audio Receiver)

In CIS mode, the LE523 acts as a standard Bluetooth receiver, allowing you to stream audio from your mobile phone, tablet, or other Bluetooth-enabled devices to a wired speaker, headphones, or car audio system.

• Activation: Switch the device to CIS mode using the Mode Key.
• Pairing: On your audio source device (e.g., smartphone), search for Bluetooth devices and select "LE523" to pair.
• Audio Output: Connect your wired headphones or speaker to the 3.5mm AUX output port of the LE523.
• Control: Use the Up/Down keys on the LE523 to adjust volume. Click the ENC button to play/pause music.

6.2 BIS Mode (Bluetooth Broadcast Transmitter)

In BIS mode, the LE523 functions as a broadcast transmitter, sending audio from a connected source to multiple RX (receiver) devices simultaneously. This is ideal for tour guides, silent discos, or multi-room audio distribution.

• Activation: Switch the device to BIS mode using the Mode Key.
• Audio Input: Connect your audio source (e.g., microphone, mobile phone, AUX device) to the appropriate input port (MIC, 3.5mm AUX, or via Bluetooth).
• Input Selection: Click the 'Broadcast TX Input' switch key to cycle through AUX, MIC, or BT input channels. Intelligent priority switching ensures broadcast continuity.
• Broadcasting: The LE523 will now broadcast the selected audio. Ensure your RX devices are in RX mode to receive the broadcast.
• Control: Use the Up/Down keys to adjust the input volume.

6.3 RX Mode (Bluetooth Broadcast Receiver)

In RX mode, the LE523 acts as a receiver for audio broadcasts from a BIS transmitter. This allows multiple individuals to listen to the same audio stream.

• Activation: Switch the device to RX mode using the Mode Key.
• Reception: The LE523 will automatically search for and connect to nearby BIS transmitters.
• Audio Output: Connect your headphones to the 3.5mm AUX output port of the LE523.
• Control: Use the Up/Down keys on the LE523 to adjust the output volume.

7. ENC Noise Reduction

The LE523 features Environmental Noise Cancellation (ENC) to reduce background noise, particularly useful when using the microphone input in BIS mode.

• To Activate/Deactivate ENC: In BIS mode, when using MIC input, double-click the ENC button.

8. Multi-Source Input

In BIS (Broadcast TX) mode, the LE523 supports multiple audio input sources:

• 3.5mm AUX Input: Connect devices with a 3.5mm audio output.
• MIC Input: Use an external microphone for voice broadcasting.
• Bluetooth Input: Pair a Bluetooth device (e.g., smartphone) to stream audio wirelessly to the transmitter.

To switch between these input sources, click the 'Broadcast TX Input' switch key. The device intelligently prioritizes inputs to ensure continuous broadcasting.

9. User Tips

• For optimal broadcast range, ensure the transmitter and receivers are in an open environment with minimal obstructions.
• When using the microphone input, activate ENC for clearer voice transmission, especially in noisy surroundings.
• Keep the device charged for extended use, particularly in broadcast modes which offer longer battery life.
• If experiencing connection issues, try resetting the device by long-pressing the Mode Key for 3 seconds.
• Ensure all receiving devices are set to RX mode to properly pick up the broadcast signal from the BIS transmitter.

10. Troubleshooting

10.1 No Power

• Ensure the device is fully charged. Connect the Type-C charging cable and check if the charging indicator light is on.
• Verify the ON/OFF switch is in the 'ON' position.

10.2 No Audio Output/Input

• In CIS/RX Mode: Check if your headphones/speakers are correctly connected to the 3.5mm AUX output port. Ensure the volume is not muted or too low.
• In BIS Mode: Verify the audio source is properly connected to the input port (AUX, MIC, or Bluetooth). Use the 'Broadcast TX Input' switch key to select the correct input channel. Ensure the input volume is adequate.

10.3 Bluetooth Pairing Issues (CIS Mode)

• Ensure the LE523 is in CIS mode and discoverable.
• Turn off and on Bluetooth on your source device (phone/tablet).
• Try resetting the LE523 by long-pressing the Mode Key for 3 seconds.
• Move the LE523 closer to your source device.

10.4 Broadcast Connection Issues (BIS/RX Modes)

• Ensure the transmitter (BIS) and receivers (RX) are within the 100m barrier-free range.
• Verify both transmitter and receivers are in the correct broadcast modes (BIS for transmitter, RX for receivers).
• Minimize physical obstructions between the transmitter and receivers.
• Try restarting both the transmitter and receiver devices.

10.5 Poor Audio Quality / Noise

• If using MIC input in BIS mode, double-click the ENC button to activate noise reduction.
• Ensure all cables are securely connected.
• Reduce interference from other electronic devices.
• Check the audio source quality.
