Preparing the headsets for use

Adjusting the headband

For good noise attenuation and best possible comfort, the headband has to be adjusted to properly fit your head:

￿Wear the headset so that the headband runs over the top of your head.

￿Adjust the length of the headband so that

•your ears are completely inside the ear cushions,

•you feel even, gentle pressure around your ears,

•a snug fit is ensured.

Note:

Make sure not to squeeze any connecting cable when adjusting the headband. Squeezing can damage the connecting cables.

￿Turn on the NoiseGard™ active noise compensation by setting the ON/OFF switch

to ON ( “Turning NoiseGard™ on/off”).

￿Final adjustment is best made in a noisy environment.
