TX (Transmitter) Mode Operation
In TX mode, the device transmits audio from a non-Bluetooth source to Bluetooth headphones or speakers.
- Ensure the TX/RX switch is set to TX.
- Connect the Aisidra device to the audio output (e.g., headphone jack, RCA output) of your TV, PC, MP3 player, etc., using the appropriate audio cable.
- Power on the Aisidra device. It will automatically enter pairing mode (indicator light will flash).
- Put your Bluetooth headphones or speakers into pairing mode.
- Place the Aisidra device and your Bluetooth audio device close to each other. They should pair automatically within a few seconds. Once paired, the indicator light on the Aisidra device will turn solid.
- Adjust the volume on your connected Bluetooth headphones/speakers or the source device.
RX (Receiver) Mode Operation
In RX mode, the device receives audio from a Bluetooth source (like a smartphone) and outputs it to wired speakers or earphones.
- Ensure the TX/RX switch is set to RX.
- Connect the Aisidra device to the audio input (e.g., AUX input) of your wired speaker, car stereo, or wired earphones using the appropriate audio cable.
- Power on the Aisidra device. It will automatically enter pairing mode (indicator light will flash).
- On your smartphone or other Bluetooth-enabled device, search for Bluetooth devices and select "Aisidra BA010" (or similar name) from the list to pair.
- Once paired, the indicator light on the Aisidra device will turn solid.
- Play audio on your smartphone, and it will be transmitted wirelessly to your wired audio system. Adjust volume from your smartphone or the wired audio system.
Dual Device Pairing (TX Mode)
The Aisidra device can connect to two Bluetooth headphones or speakers simultaneously in TX mode:
- First, pair the Aisidra device with your first Bluetooth headphone/speaker as described in the TX Mode Operation section.
- Once the first device is successfully paired, put your second Bluetooth headphone/speaker into pairing mode.
- The Aisidra device will automatically search for and connect to the second device. Once both are connected, the indicator light will remain solid.
- Audio will now be transmitted to both paired devices simultaneously.
Maintenance
To ensure the longevity and optimal performance of your Aisidra Bluetooth Transmitter Receiver, follow these maintenance tips:
- Cleaning: Use a soft, dry cloth to clean the device. Do not use liquid cleaners or aerosols.
- Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Care: Although the device can work while charging, avoid leaving it continuously plugged in for extended periods after it's fully charged to prolong battery life. If storing for a long time, charge the battery to about 50% every few months.

Troubleshooting
If you encounter issues with your Aisidra Bluetooth Transmitter Receiver, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound or distorted audio | Incorrect mode selected; Loose audio cable connection; Volume too low; Device not paired. | Ensure TX/RX switch is in the correct position. Check all audio cable connections. Increase volume on both the Aisidra device and the connected audio device. Re-pair the devices. |
| Cannot pair with a device | Device not in pairing mode; Too far from the other device; Other device not in pairing mode; Interference. | Ensure the Aisidra device is powered on and its indicator light is flashing (pairing mode). Place devices within 1 meter of each other. Ensure the other Bluetooth device is also in pairing mode. Turn off other Bluetooth devices nearby to reduce interference. |
| Audio delay (latency) | Paired device does not support low latency codec. | For optimal low latency performance, ensure both the Aisidra device and your Bluetooth headphones/speakers support low latency codecs (e.g., aptX Low Latency). If not, some delay may be unavoidable. |
| Device not turning on | Low battery; Faulty charging cable/adapter. | Charge the device fully. Try a different USB charging cable or power adapter. |
