5. Setup
Follow these steps to set up your Bluetooth Audio Module:
- Identify Connections: Locate the power input terminals (typically marked VCC/GND or +/–) and audio output terminals (typically marked L/R/GND or OUT_L/OUT_R/GND) on the CA-6928 module.
- Power Connection: Connect a compatible DC power supply (refer to specifications for voltage range) to the module's power input terminals. Ensure correct polarity.
- Audio Output Connection: Connect the audio output terminals of the CA-6928 module to the audio input of your amplifier board. Use appropriate shielded audio cables to minimize interference.
- Initial Power On: Once all connections are secure, apply power to the module. An indicator light (if present) should illuminate, and the module will enter pairing mode.
6. Operating Instructions
Bluetooth Pairing:
- Activate Module: Ensure the CA-6928 module is powered on and in pairing mode (usually indicated by a blinking LED).
- Enable Bluetooth on Device: On your smartphone, tablet, or computer, go to the Bluetooth settings and enable Bluetooth.
- Search for Devices: Your device will scan for available Bluetooth devices. Look for a device named similar to "BT-AUDIO" or "CA-6928".
- Connect: Select the module's name from the list to initiate pairing. Once connected, the indicator light on the module may change to a solid state or blink slower.
- Play Audio: You can now play audio from your device, and it will be transmitted wirelessly to the CA-6928 module and through your connected amplifier.
Disconnecting:
To disconnect, simply turn off Bluetooth on your source device or select "Disconnect" from the Bluetooth settings. The module will automatically re-enter pairing mode, ready for a new connection.
7. Maintenance
- Cleaning: Use a soft, dry cloth to clean the module. Do not use liquid cleaners or solvents.
- Storage: When not in use for extended periods, store the module in a cool, dry place, away from dust and direct sunlight.
- Inspection: Periodically check all connections for looseness or corrosion.
