FAQs
Frequently Asked Questions
How is Navii different from other microprocessor knees?
Navii stands apart from other microprocessor knees by offering instant stance control, effortless swing, enhanced modes for navigating stairs and ramps, and seamless adaptability to various terrains, providing a more natural and confident experience.
Is Navii waterproof?
Yes, and even more than that! While most waterproof MPKs are only rated for freshwater submersion, Navii is designed to withstand freshwater, saltwater, chlorine, mud, and sand. So, go ahead and enjoy the beach, pool, or trails without worry.
How do I clean my Navii?
Cleaning your Navii is simple. Because it's corrosion-resistant, a quick rinse with a hose or in the shower is all you need to keep it clean and working its best. Always make sure your Navii is powered off and that the protective cover is removed for cleaning.
Can I wear Navii in saltwater or chlorine water?
Absolutely! Navii is built to withstand these environments, along with sand and mud. It’s designed to keep up with your active lifestyle, wherever it takes you.
How can I buy additional covers?
Additional covers that fit your style and needs may be ordered directly from your prosthetist.
Should I wear my protective cover when I am in the water?
While the cover itself is waterproof, we generally recommend removing it when swimming or fully submerging your Navii. This allows for optimal performance and drying. However, you can choose to wear it in the water if you prefer.
What is the purpose of the covers?
The covers offer both functional protection and aesthetic customisation. They help protect the knee from everyday wear and tear while also allowing you to personalise its appearance.
Does Navii have modes for different activities?
Navii is designed to seamlessly adapt to your movements without needing to manually switch between modes. It intelligently adjusts to different activities, whether you’re walking, running, hiking, biking, or climbing stairs.
What happens if my battery dies?
You will get a series of warning vibrations and an auditory signal indicating low battery charge, at this point, you can engage the manual lock, or use the solution without power.
How do I check the battery level on my Navii?
You can easily check the battery level using the Össur Logic app or by tapping the button on the device.
What else can the Ossur Logic app help me with?
In addition to monitoring battery levels, you can track your step count. The app includes biofeedback exercises that can help improve your gait and overall use of the device so you can get the most out of Navii. Additionally, your prosthetist can use it to customise your profile settings to fit your needs and gait style, and also create activity reports to track your progress and help support reimbursement claims.
