Dual Device Connection (Multi-Point)
The J205 supports connecting to two Bluetooth devices simultaneously:

Troubleshooting
If you encounter issues with your iDIGMALL J205, please refer to the following common solutions:
- Device will not power on: Ensure the battery is charged. Connect the device to a power source using the USB-C cable and try again.
- Cannot pair with a device:
- Ensure the J205 is in pairing mode (indicator light flashing).
- Make sure Bluetooth is enabled on your source device (smartphone, tablet).
- Check that the J205 is within the Bluetooth range (up to 33 feet or 10 meters).
- Turn off and on both the J205 and your source device, then attempt pairing again.
- Clear the Bluetooth pairing list on your source device and try to pair again.
- No audio or poor sound quality:
- Verify that the J205 is correctly connected to your audio system via the 3.5mm or RCA cable.
- Ensure the volume on both the J205 and your source device/audio system is turned up.
- Check that the correct input source is selected on your audio system (e.g., AUX).
- Move the source device closer to the J205 to rule out range issues or interference.
- Ensure no other Bluetooth devices are interfering with the connection.
- Automatic shutdown: The J205 is designed to shut down after 5 minutes without a Bluetooth connection to save power. This is normal behavior.
- Cannot connect to Bluetooth headphones/speakers: The J205 is a Bluetooth receiver, not a transmitter. It is designed to receive audio from a source device and output it to wired audio systems, not to transmit to other Bluetooth audio devices.
- No hands-free calling: This device does not have a built-in microphone and therefore does not support hands-free calling. It is for music streaming only.
