any reason, you may use the glued surface mounting adapter to attach
the clamp unit on the external surface of the helmet.
1. Remove the back plate of the clamp unit completely.
2. Put the speaker port through the glued external adapter.
3. Hook on the adapter to the clamp unit then screw in the glued
external adapter to the clamp unit.
4. Locate a proper surface on the helmet to attach the unit then clean
the helmet surface location with a moistened towel and allow to
dry thoroughly.
5. Peel off the cover of the adhesive tape of the adapter and attach
the unit on the proper surface of your helmet.
Note:
Sena recommends the clamp unit over the glued surface mounting
adapter. Even though the glued surface mounting adapter is provided for
convenience, Sena does not assume any responsibility for use of it. Users
may have to use the glued adapter at their own risk and responsibility.
