Note: Depending on the size and shape of your helmet, you may
need to change the thickness of the rubber pad between the clamp
plates using the two extra rubber pads in the box. To increase the
overall thickness, attach the thinner one to the original rubber pad
or replace the original rubber pad with the thicker one.

centered to your ear, in the ear pockets of the helmet. If the helmet
has deep ear pockets, you can use the speaker pads to place the
speakers closer to your ears.

Mobile Phone Pairing, Second Mobile Phone Pairing and GPS
Pairing. The headset can also be paired with up to three other Sena
