Troubleshooting

If you encounter issues with your JR-CB3 adapter, refer to the following common problems and solutions:

Q: Why can't the receiver be connected?

• It may be that the receiver has been connected to another device (such as a computer or mobile phone). Please disconnect it from the previously connected device and attempt to reconnect.
• For iPhone users, if Bluetooth does not automatically refresh, manually click "JR-CB3" in your phone's Bluetooth interface.
• If the above steps fail, you can try restoring the receiver to factory settings (refer to the full user manual for specific instructions if available).

Q: Why is the sound of the receiver too low?

• For Android users, ensure the playback channel of the mobile phone is turned on. Go to your phone's Bluetooth settings, click the icon next to the connected device, and ensure "media channel and call channel" are enabled.
• For iPhone users, check your phone's "Settings" interface to see if there is a maximum volume limit enabled.
• Due to different operating systems, the volume of the receiver may not be synchronized with your phone or car audio. Manually adjust the volume on your mobile phone, the JR-CB3 adapter, and your car audio system independently.
