What you need
- A computer with a free USB port. Plug directly into the computer rather than through a hub where possible.
Step by step
-
Fit it. Adjust the headband and boom so the microphone sits about two fingers from the corner of your mouth.
-
Connect it. Connect the USB cable to the computer; it powers the EncorePro 300 Series. Plug straight into the computer rather than a hub where you can.
-
Set up USB mode. Connect the EncorePro 300 Series to the computer by USB. In Teams, Zoom or Meet, open the device settings and select the EncorePro 300 Series as the microphone and speaker.
-
Update the firmware. USB peripherals update via Poly Lens Desktop or Windows Update. See Updating the firmware below.
-
Make a test call. Make a test call and ask the other side whether you're clear and at a good level; check mute sync between the headset and the app.
