Putting on the headset
The headband has two independent settings. Tighten the headband then adjust it until the cups are
correctly positioned on your ears. For maximum efficiency, the headband must be perfectly adjusted and
the ear pads must provide a perfect seal over your ears.
Tip: remember to slacken your headset before taking it off.
Turning the headset on and off
To turn your headset on, simply turn the button ON/OFF in a clockwise direction. A light "click" will tell
you that you have just turned the headset on. The red led situated on the right cup turns on.
To turn off your headset, turn the button in an anticlockwise direction. A light "click" will tell you that

To amplify the sound, once your headset is turned on, simply continue turning the button on each cup in
a clockwise direction.
