  • If the microphone and loudspeaker are close to each other this can create a feedback loop. To prevent the loop turn off the computer's loudspeakers. For example, click the loudspeaker icon in the Windows taskbar and select Mute.

If you cannot find the loudspeaker icon in the taskbar, open the volume controller from the Windows Control Panel.


  • Background noise or loud sounds (e.g. music, speaking or a phone ringing) may cause interference with SonicLink data transmission. Eliminate the noise and try the transmission again.

  • If the microphone is selected as a playback device it may interfere with SonicLink transmission. Check that the microphone is not selected as a playback media in Control PanelSounds and Audio Devices/Sound. If disabling the microphone as playback media does not help, mute all playback devices and try the transmission again.

  • The internal infrared port (only on laptops) may interfere with SonicLink with its regular checking for IR data availability. You can disable the internal infrared port in the Device Manager to block the IR port checking. Alternatively, you can try to extend the time delay for IR port checking to allow SonicLink transmission to finish.

4. In the WebLink software, try with SonicLink Low Volume.
Try with different distances. Distance between microphone and Polar product can vary from 0,5 cm up to 15 cm.

If the microphone is working and no other application (e.g. iTunes) is reserving it and/or sound card, the data transfer problem might stem from the sound card itself.
