2. FITTING AND ADJUSTMENT

Note! Brush aside hair around your ears so the ear cushions (A:5) fit snugly.
Spectacle frames should be as thin as possible and fit close to the head to minimize acoustic leakage.
2.1 Headband (figure D)
(D:1) Slide out the cups (A:7).Tilt the upper part of the headset outwards to ensure the wires are outside the headband wires (A:3).
(D:2) Adjust the height of the cups by sliding them up or down while holding the headband in place.
(D:3) The headband should be positioned across the top of your head.
2.2 Helmet attachment (figure E)
(E:1) Insert the helmet attachment in the slot on the helmet and snap it into place.
(E:2) Working mode. To switch the unit from ventilation mode to working 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 working
mode as this can cause noise leakage.
(E:3) Ventilation mode. Avoid placing the cups against the helmet as this prevents ventilation (E:4).
