To install the headset into some head protective devices, one or both of the earcups may need
to be temporarily removed.
Earcup Removal and Attachment
1.
Use a #1 Phillips screw driver to remove the ¼ turn fastener holding each side of the
earcup to the metal stirrup.
2.
To remove, gently rotate the fastener ¼ turn counter clockwise (CCW). The cam will
disengage, and the fastener will stop turning when the fastener is disengaged. Too much
applied torque may break the fastener or damage the insert.
3.
Pull the stirrup away from the cup. The fastener is captured on the stirrup so it will not
fall away.
4.
To reinstall the cup, insert the fastener into the receptacle, and gently rotate the fastener
¼ turn clockwise (CW) to reengage the fastener. A click should be heard as the fastener
cam engages. Too much torque may cause damage to the fastener or the insert.
5.
Gently try to pull the stirrup away from the earcup to verify the fastener is reengaged.
6.
Repeat for the opposite earcup side.
