Putting on the headset
Use one hand to hold
the headset steady, and
use your other hand to
adjust the velcro straps
on both sides of the
headset.
Make sure the headset
and its padding fit firmly
on your forehead, and
then pull the rear strap
into place over the back
of your head.
Adjust the velcro strap on
the top until the headset
fits firmly.
