2. Attach the headset main unit to the clamp. Insert the main unit in the clamp
until you feel the click that signals a secure attachment.
3. If you have any problem mounting the clamp unit on the helmet for any
reason, you may use the glued surface mounting plate which can be attached
to the external surface of the helmet.
- Locate a proper surface on the helmet to attach the unit, clean the helmet
surface location with a moistened towel, and allow to dry thoroughly.
- Peel off the cover of the adhesive tape of the plate and attach the unit on the
proper surface of your helmet.
Note:
Sena recommends the clamp unit over the glued surface mounting plate. Even though the glued
surface mounting plate is provided for convenience, Sena does not assume any responsibility for
use of it. Users may have to use the glued plate at their own risk and responsibility.
4. Place the helmet speakers along with the velcro pads, 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.
5. Attach the boom microphone between the internal padding and the external shell. The
boom microphone should be mounted on the inside surface of the external shell so it is
facing properly towards your mouth. Please make sure that the microphone is located

first time, you need to do the pairing operation. It can be paired with Bluetooth
mobile phones, Bluetooth stereo devices such as MP3, or motorcycle specific
Bluetooth GPS, and with other SENA Bluetooth headsets. This pairing operation
is only required once for each Bluetooth device. The headset will remain paired
with the devices and automatically connects to the paired devices again when
they are within range. You will hear a high tone single beep and a voice prompt
when the headset connects to the paired device automatically: “Phone
connected” to a mobile phone, “Media connected” to a Bluetooth stereo
device.
