    1.2 General Information

This product is a Motorcycle Flip-Up helmet.
Do not use it for any other purpose than riding a motorcycle. If you use the helmet for anything else, it may not provide sufficient protection in an accident. No helmet can protect the wearer against all possible impact scenarios.
For maximum protection, the helmet must fit properly on the head and its retention strap securely fastened under the chin. With the retention system comfortably but firmly adjusted, the helmet should allow sufficient peripheral vision when secured. If the helmet is too large, it may move on your head while riding. If the helmet can be removed when pulled from the back in an upward and forward direction, it’s not fitted properly. This could cause the helmet to obstruct your vision while riding or come off in an accident, resulting in personal injury or death. Please refer to Section 2: “Wearing the Helmet” for more details about properly securing and wearing your helmet.

2.14 Pre-Ride Helmet Inspection
WARNING: This product is a motorcycle helmet. Do not use it for any other purpose than riding a motorcycle. If you use the helmet for anything else, it may not provide sufficient protection in an accident. No helmet can protect the wearer against all possible impact scenarios.
2.14.1 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.
2.14.2 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.
2.15 Checking the Shield Visor
Before every ride, clean the shield visor, check that if 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.
CAUTION:

  • A heavily scratched shield visor considerably interferes with visibility and should be replaced if necessary before riding.
  • Stop riding if visibility is poor.

PRING THE BLUETOOTH SYSTEM WITH OTHER BLUETOOTH DEVICES

When using the Bluetooth system with other Bluetooth devices for the first time, they will need to be “paired.” This enables them to recognize and communicate with one another whenever they are within range.
The Bluetooth system can pair with multiple Bluetooth devices such as a mobile phone, GPS, MP3 player or Sena SR10 Two-Way Radio Adapter via Mobile Phone Pairing, Second Mobile Phone Pairing and GPS Pairing. The Bluetooth system can also be paired with up to three other Sena Bluetooth systems.

MESH INTERCOM

7.1 What is Mesh Intercom?

Mesh Intercom™ is a dynamic communication system created by Sena that provides instant and effortless bike-to-bike communication without a pre-grouping process. Mesh Intercom allows riders to connect and communicate with nearby users without the need to pair each Bluetooth system together.
The working distance between each IMPULSE in Mesh Intercom can be up to 2 km (1.2 miles) in open terrain. In open terrain, the Mesh can be extended up to 8 km (5 miles) between a minimum of six users. Within the same channel in Open Mesh™ or the same private group in Group Mesh™, six users can talk at the same time and enjoy the optimal quality for their conversation. SENA Impulse
Motorcycle Bluetooth Helmet with Mesh Intercom - Fig 5

7.1.1 Open Mesh
Open Mesh is an open group intercom function. Users can freely communicate with each other in the same Open Mesh channel and select which channel (1-9) to use through the Bluetooth system.
It can connect with a virtually unlimited number of users in each channel.
Open Mesh SENA Impulse Motorcycle Bluetooth Helmet with Mesh Intercom -
Fig 67.1. 2 Group Mesh
Group Mesh is a closed group intercom function that allows users to join, leave, or rejoin a group intercom conversation without pairing each Bluetooth system. Users can freely communicate with each other in the same private group in Group Mesh.
For closed intercom conversations using Mesh Intercom, a Group Mesh needs to be created by the users. When users create a private group in Group Mesh by Mesh Grouping, the Bluetooth system automatically switches from Open Mesh to Group Mesh. Up to 24 users can all be connected in each private group.

Terminate Group Intercom SENA Impulse Motorcycle Bluetooth Helmet with
Mesh Intercom - Fig 428.7 Mesh Intercom Conference with Bluetooth Intercom Participant

Users can use the existing Bluetooth intercom and Mesh Intercom function at the same time. In this case, it is recommended to communicate with other Sena Bluetooth systems via Bluetooth intercom connection and use Mesh Intercom between IMPULSE Bluetooth systems. A user who is in Open Mesh or Group Mesh when using Mesh Intercom is able to include up to 3 of their Bluetooth intercom friends. You can start a Two-Way Intercom conversation with one of your three Intercom Friends to include them in the Mesh.
Note:

  • The audio quality will be reduced if a IMPULSE connects to 2 or more Bluetooth intercom friends while in Open Mesh or Group Mesh when using Mesh Intercom.
  • If a closed loop is created, as shown below, each user will experience severe noise issues. Sena recommends that a closed loop not be created.
  • SENA Impulse Motorcycle Bluetooth Helmet with Mesh Intercom - Fig 43If Bluetooth intercom is accidentally turned on during Mesh Intercom communication between IMPULSE Bluetooth systems, as shown below, you will hear a voice prompt, “Mesh intercom disabled. Bluetooth intercom connected” every 1 minute. If you
    turn off the Bluetooth Intercom or turn off the Mesh Intercom, the voice prompt will no longer come out.SENA Impulse Motorcycle Bluetooth Helmet with
Mesh Intercom - Fig 44

UNIVERSAL INTERCOM

Universal Intercom allows you to have intercom conversations with users of non-Sena Bluetooth headsets. Non-Sena Bluetooth headset can be connected to the Sena Bluetooth system if they support the Bluetooth Hands-Free Profile (HFP). You can pair the Bluetooth system with only one non-Sena headset at a time. The intercom distance depends on the performance of the Bluetooth headset to which it’s connected. When a non-Sena Bluetooth headset is paired with the Bluetooth system while another Bluetooth device is paired via Second Mobile Phone Pairing, it will be disconnected.
9.1 Universal Intercom PairingSENA Impulse Motorcycle Bluetooth Helmet
