Replacing microphone and windscreen

Attaching/Detaching

The Edge features a field replaceable microphone and a screw-on removable windscreen. 3M Quest suggests that the user replace the windscreen whenever dirt has accumulated on the windscreen prior to measuring data.

NOTE: If you ordered an Edge kit, extra windscreen(s) will be included in your case.

Attaching/Detaching the windscreen and microphone

1.First, unscrew the windscreen by turning the red ring (not the foam!) in a counterclockwise direction.

2.If you are replacing the windscreen, screw on a new windscreen in a clockwise direction until it fits firmly.

3.To unscrew the microphone, turn the microphone in a counterclockwise direction until it is removed.

4.To attach a new microphone, screw the microphone on clockwise until it fits tightly.

•The following diagram illustrates how to assemble these two devices.
