If your PowerConf S330 does not turn on after being connected to the computer, you can try the following steps:
 

1. Plug it into another USB port on your computer ( make sure the output from your computer's USB port to the speakerphone is more than 5V/2A, otherwise the speakerphone cannot work normally).

2. Try a different computer.
 

Note: 

Once the speakerphone is connected and powered on, all buttons will flash white for 2 seconds and then stay solid white.
 

If this issue persists, please contact us for further assistance. Please make sure to mention that you have tried the steps in the FAQ so that our agents do not ask you to repeat these steps.
