Why is my BenQ Speaker not charging?
If your BenQ Speaker isn't charging, avoid charging it in high-temperature environments. If the speaker overheats and powers off, the LED will flash red and green alternately. Also, make sure you are using the adapter and cable that came with the package.
How to switch the audio from the original audio player to BenQ Speakers?
To switch the audio to your BenQ Speakers: 1. **Bluetooth connection**: Go to your Bluetooth device's audio menu and change the output to treVolo U. On a PC, for music/videos, switch the microphone to the PC's audio device and the speaker to Speaker (treVolo U stereo). For online courses/calls, switch both microphone and speaker to Headset Earphone (treVolo U Hands-Free AG Audio). 2. **Audio cable connection**: For MAC, go to Sound > Output > and switch to External Headphones. For Windows PC, turn on Sound settings > Output > and switch to speaker/headphone. If you have trouble connecting with the audio cable, test with wired 4PIN earphones. If audio plays smoothly, switch the audio device as described above.
What to do if some apps are unable to use BenQ treVolo U for audio input?
If some apps can't use treVolo U for audio input: * Check if you can switch the audio input device to treVolo U in the app or phone settings. * If not, make a phone call and set the audio device as Bluetooth to use the speaker for input. * If both fail, use the provided audio cable. Plug the audio cable into the speaker first, then into your device.
Why BenQ treVolo U does not automatically switch to "Live Learning" mode when connected by audio cables?
When connected via audio cable, treVolo U doesn't automatically switch to "Live Learning" mode because the analog audio signal cannot be detected and switched automatically to HFP (Hands-Free Profile) which can be detected digitally under Bluetooth connection. You can manually switch the mode to Live Learning to improve the quality of the course.
What to do if the BenQ treVolo U App is unable to find treVolo U?
If the treVolo U App can't find treVolo U: * Ensure the speaker is on, then restart the app. * If it still can't connect, restart the speaker, reactivate Bluetooth on your device, and move closer to the speaker. * Avoid calls or pausing videos, then open the App and go to the Search page. * Pause Bluetooth A2DP for music or videos. * Avoid using a 2.4GHz WiFi network for streaming music; switch to 5GHz or cellular network instead.
