If people on the other side complain that they cannot hear you clearly, please check if the following steps can improve the voice picking ability of the microphones:
 

1. Keep your distance from the speakerphone within 3 meters (For PowerConf S500, its microphone coverage can be extended to 5 meters).
2. Keep the PowerConf speakerphone at its latest firmware version.
3. It's recommended to use a USB connection when operating on computers and laptops.
4. In order to deliver a consistent, clear and real sound to the other side, you are suggested to use the speakerphone in a relatively quiet environment.

If the above solutions cannot solve your issue, 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.
