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 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.
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 V-straps 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.
1. Unfasten the chinstrap.
2. Gently pull the padded V-straps 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.
Checking the Bluetooth Module’s Battery Level
There are two ways to check battery level:
1. Visually, with LEDs when powering on.
Note: Blinking LEDs alternate from blue to red when battery power is low.
2. Audible method: Press and hold the Center Button and the (+) Button for 3 more seconds as the headset powers on. A prompt will announce the remaining battery level.
Sena Device Manager
The Sena Device Manager allows you to upgrade the Bluetooth Communication Module’s firmware and configure its settings directly from your PC or Apple computer. Using this software, you can assign speed dial presets, FM radio station presets and more.
Sena Smartphone App
The Sena Smartphone App allows you to configure the Bluetooth Communication Module’s settings, as well as access the User’s and Quick Start Guides. To do so, pair your mobile phone with your Cavalry Bluetooth Half Helmet (please refer to Section 3: “Pairing the Helmet with other Bluetooth Devices” for more details). Run the Sena Smartphone App and configure the settings directly from your smartphone.
The Cavalry Bluetooth Half Helmet supports firmware upgrades.
