Checking the Exterior
Check the helmet regularly for damage. Small, superficial scratches will not impair the
helmet’s protective qualities. In the case of more serious damage (cracks, dents, flaking
and cracking paint, etc.), the helmet should no longer be used.
Checking the Chinstrap
1. Ensure that the chinstrap is properly routed under your chin.
2. To test the chinstrap tension, slip your index finger under the chinstrap and pull. If the chinstrap is loose under the chin, it needs to be tightened. If the chinstrap loosens when you pull on it, the helmet is not properly fitted. Undo the chinstrap completely and try fastening it again, then repeat the test.
3. If you are unable to fasten the chinstrap so that it fits firmly against the chin, check that
your helmet is still the right size for you.
Note: Repeat the test after each adjustment.
Caution: : Never ride with the chinstrap unfastened or incorrectly adjusted. The
chinstrap should fit correctly and should not become loose when pulled. The fastener
is not correctly closed if the chinstrap becomes loose when pulled.
Checking the Face Shield
Before every ride, clean the face shield, check that it functions properly and that
its surface is scratch- and crack-free. A malfunctioning, badly scratched or dirty shield
will considerably impair your vision and should be replaced before riding.
- A heavily scratched face shield considerably interferes with visibility and should be replaced if necessary before riding.
- Stop riding if visibility is poor.
Putting on the Helmet
1. Unfasten the chinstrap.
2. Gently pull the chinstrap outward and slide the helmet onto your head.
Note: A “chinstrap” is the nylon webbing that goes through the D-Rings.
3. Route the chinstrap under your chin, then thread it through both D-Rings.
4. To fasten securely, thread chinstrap back through the D-Ring closest to your neck, and pull.
Removing the Helmet
1. Loosen the chinstrap by pulling the red tab attached to the D-Rings.
2. Pull the chinstrap out from within the D-rings.
3. Gently pull the padded chinstrap outward and slide the helmet off your head.
Advice: Fastening the chinstrap after removing the helmet will help avoid
scratching surfaces it’s placed upon.
Ear Pad Replacement
The helmet comes pre-installed with two Ear Pads. If the Ear Pads are too tight and uncomfortable
while wearing the helmet then you can switch to the optional Ear Pads, which are thinner, included in the package.
To replace the Ear Pads, pull the currently installed Ear Pad away from the speaker with a firm grip. Place the desired Ear Pad over the speaker and push down on the Ear Pad with firm pressure.
The face shield is coated with an anti-scratch treatment. Removing and installing the shield is quick and easy:
1. Lift the shield upward so that it is in the most open position.
2. Release the locking mechanism by pulling it in the direction of the arrow towards the front of the helmet.
3. Firmly lift the shield away from the locking mechanism.
4. Repeat on the other side.
1. Keep the locking mechanism open by pushing it in the direction of the arrow.
2. Align and insert the shield guide into the locking mechanism as shown.
3. Release the locking mechanism to lock the shield in place. Make sure that the guide is locked
properly into the helmet.
4. Repeat on the other side.
There are two ways to check battery level:
1. Visually, with LEDs when powering on.
2. Audible method: press and hold the Center Button and the (+) Button for more than 6 seconds as the Bluetooth system powers on. A prompt will announce the remaining battery level.
• When the battery is low while in use, you will hear a voice prompt saying “Low battery”.
• If the Voice Command setting is disabled, press and hold the Center Button and the (+) Button for more than 3 seconds as the Bluetooth system powers on.
The Sena Device Manager allows you to upgrade the firmware and configure its settings directly from your PC or Apple computer.

The Audio Multitasking (Default: Enabled) setting can be found in the settings menu, accessible through Sena Device Manager or Sena Smartphone App.
Audio Multitasking allows you to have an intercom conversation while simultaneously listening to music, FM radio, or GPS instructions. The overlaid audio is played in the background with reduced volume whenever there is an intercom conversation and will return to normal volume once the conversation is finished. If this feature is disabled, any incoming or outgoing intercom will interrupt your audio channel.
Intercom-Audio Overlay (Default: 6)
The Intercom-Audio Overlay Sensitivity setting can be found in the settings menu, accessible through Sena Device Manager or Sena Smartphone App.
The music, FM radio and GPS volume will be lowered to play in the background if you talk over the intercom while the overlaid audio is playing. You can adjust the intercom sensitivity to activate this background audio mode. Level 1 has the lowest sensitivity and level 10 has the highest sensitivity.
Note: If your voice is not louder than the sensitivity of the selected level, the overlaid audio will not be lowered.
Audio Overlay Volume Management (Default: Disable)
The Audio Overlay Volume Management setting can be found in the settings menu, accessible through Sena Device Manager or Sena Smartphone App.
The music, FM radio and GPS overlaid audio reduces in volume whenever there is an ongoing intercom conversation. If Audio Overlay Volume Management is enabled, the volume level of the overlaid audio will not be reduced during an intercom conversation.
