headset, move
earloop away
from receiver and
place earloop over
your ear. The over-the-ear
configuration allows further
control by adjusting the
flexible earloop as shown.

your ears. If necessary, to
increase or decrease tension
on your head, bend the
metal part of headband
inward or outward for
desired comfort. Push
receiver close to your ear until
it feels comfortable and you
can hear the sound from the telephone clearly.
