FAQ (Frequently Asked Questions)
Q: How to resolve static issues?
A: 1. Ensure no power lines are located close to the JR-CCB02, as unshielded lines can cause electromagnetic interference and reduce transmission signal quality, leading to background noise. 2. Signal strength may be affected in mountainous areas, densely built-up environments, or tunnels. It is recommended to retune your car radio to an unused station and then reconnect the device.
Q: How to achieve better voice quality during calls?
A: Confirm that your car radio is successfully connected to an unused station before initiating a call. If noise persists, consider closing the car windows during the call.
Q: What to do if the sound is too low during music playback or calls, or if there is no sound when answering a call?
A: 1. Adjust the volume on both your mobile phone and the JR-CCB02 to their maximum levels. 2. Press the multifunctional button. Some mobile phones may default to transmitting call audio through the handset when using the phone's answer button.
Q: Why does the JR-CCB02 fail to connect wirelessly even when discoverable by the phone?
A: 1. Verify that your phone's Bluetooth function is enabled and operating correctly. 2. Ensure the JR-CCB02 is not currently connected to other devices; disconnect other devices if necessary. If the problem persists, remove all previous "CCB02" entries from your phone's Bluetooth settings and attempt to reconnect.
Q: Can the JR-CCB02 remember the connection with the mobile phone?
A: The JR-CCB02 is equipped with a memory connection function. However, some mobile phones may disable automatic Bluetooth connection to conserve battery power, requiring manual reconnection.
