5. Setup and Pairing

The BM-LE505 can operate in two modes: Transmitter (TX) and Receiver (RX). Ensure the device is sufficiently charged before use.

5.1. Transmitter (TX) Mode Setup

Use TX mode to send audio wirelessly from a non-Bluetooth device (e.g., TV, PC, MP3 player) to Bluetooth headphones or speakers.

1. Switch to TX: Locate the mode switch on the side of the adapter and slide it to the 'TX' position.
2. Connect Audio Source: Plug one end of the 3.5mm audio cable into the BM-LE505's audio input port and the other end into the audio output (headphone jack) of your non-Bluetooth device (e.g., TV, PC).
3. Enter Pairing State: Press and hold either the 'A' or 'B' pairing button on the adapter. The corresponding 'A' or 'B' light will flash quickly, indicating it's in pairing mode.
4. Pair with Bluetooth Device: Put your Bluetooth headphones or speaker into pairing mode. They should automatically connect to the BM-LE505. Once connected, the 'A' or 'B' light on the adapter will remain solid.

5.2. Receiver (RX) Mode Setup

Use RX mode to receive audio wirelessly from a Bluetooth-enabled device (e.g., smartphone, tablet, laptop) and play it through wired speakers or a car stereo.

1. Switch to RX: Locate the mode switch on the side of the adapter and slide it to the 'RX' position.
2. Connect Audio Output: Plug one end of the 3.5mm audio cable into the BM-LE505's audio output port and the other end into the audio input (AUX-in) of your wired speaker or car stereo.
3. Enter Pairing State: Press and hold either the 'A' or 'B' pairing button on the adapter. The corresponding 'A' or 'B' light will flash quickly, indicating it's in pairing mode.
4. Pair with Bluetooth Device: On your smartphone, tablet, or laptop, go to Bluetooth settings and search for 'LE505'. Select it to connect. Once connected, the 'A' or 'B' light on the adapter will remain solid.

6. Operating Modes and Features

6.1. Dual Pairing Support

The BM-LE505 supports connecting to two Bluetooth devices simultaneously, allowing for shared audio experiences.

• In TX Mode: Connect two Bluetooth headsets or two Bluetooth speakers to share audio signals from a single source.
• In RX Mode: Connect two Bluetooth devices (e.g., two smartphones) to the adapter. You can switch between the audio signals of the two connected devices at will.

6.2. Audio Codec Switching (Aptx Low Latency)

In TX mode, the BM-LE505 supports multiple audio encodings, including Aptx Low Latency, which ensures audio delay is less than 40 milliseconds for a synchronized experience. To switch between available audio CODECs (SBC, AAC, aptX, Adaptive, aptX HD, aptX LL), double-click the corresponding 'A' or 'B' pairing button. The LED indicators will change color to reflect the active codec.

• Fitness: Power your workouts with dynamic music by connecting to gym equipment or portable audio sources.
• Car Audio: Add Bluetooth functionality to your car stereo.

7. Charging and Battery Life

The BM-LE505 is equipped with a 250mAh battery, providing extended usage times. To charge the device, connect the included Type-C charging cable to the adapter's charging port and a USB power source.

• Full Charge Time: Approximately 2 hours.
• Battery Life in RX Mode: Up to 20 hours.
• Battery Life in TX Mode: Up to 12 hours.

8. Maintenance

To ensure the longevity and optimal performance of your BM-LE505:

• Keep the device dry and away from moisture.
• Clean the device with a soft, dry cloth. Do not use harsh chemicals or abrasive materials.
• Store the device in a cool, dry place when not in use, preferably in the provided storage bag.
• Avoid extreme temperatures.

9. Troubleshooting

9.1. Device Not Pairing

• Ensure the BM-LE505 is in the correct TX or RX mode.
• Make sure both the adapter and your target Bluetooth device are in pairing mode (indicated by rapidly flashing LED lights).
• Bring the devices closer together (within 1 meter).
• Turn off and on both devices, then try pairing again.
• Clear previous Bluetooth connections on your target device if necessary.

9.2. No Sound or Low Volume

• Check all audio cable connections to ensure they are secure.
• Verify that the volume on both the BM-LE505 (if applicable via connected device) and the connected audio device (headphones, speakers, TV, phone) is turned up.
• Ensure the correct audio input/output is selected on your source device (e.g., TV audio output).
• Confirm the BM-LE505 is successfully paired and connected (solid LED light).

9.3. Short Transmission Range or Intermittent Connection

• Ensure there are no significant obstacles (walls, large metal objects) between the BM-LE505 and the connected Bluetooth device.
• Move the devices closer to each other. The optimal range is up to 10 meters (33 feet).
• Avoid interference from other 2.4GHz wireless devices (Wi-Fi routers, cordless phones).
• Ensure the adapter is fully charged.

10. User Tips

• For the best audio quality and lowest latency, ensure your connected Bluetooth headphones or speakers also support aptX Low Latency when using TX mode.
• Always fully charge the device before extended use, especially for travel.
• When switching between TX and RX modes, it's good practice to power off the device briefly before changing the switch position and powering it back on.
• Keep the adapter updated with the latest firmware if available from the manufacturer's website to ensure compatibility and performance improvements.
