J:3 Work mode. To switch the unit from ventilation mode to work mode, press the headband wires inwards until you hear a
click on both sides. Make sure that the cups and the headband wires do not press on the edge of the helmet when in work
mode as this can cause noise leakage.

needed to replace the helmet attachment plate.

K:2 Attach the appropriate plate while ensuring the left (L) and right (R) designated plates are on the appropriate earmuff, if
applicable, and then tighten the screw.
