Although the helmet should work right out of the box, it’s best to give it a full charge first.
The charging port can be found on the back of the helmet. Lift the flap that is covering the port to avoid water coming in. Plug in the USB-C cable in the helmet and plug in the power in an USB-port or outlet.
The Ultra helmet has a light close to the power button which lights up red when charging and turns green when fully charged. It will take about 3-4 hours to fully charge.
How do I know when I need to charge?
With a full charge Ultra will last up to 10 hours in slow flashing mode with the lights set on maximum brightness - and even longer if you adjust the brightness & frequency in the Lumos app.
When the battery on the helmet is low, the power button will start flashing red. At this point there is approximately 30min of charge left in the helmet. When the battery of the helmet is critically low and is about to shut off, before it does so the helmet will beep several times to inform you that it is about to shut off.
You'll also be able to connect the helmet to the Lumos app and check the remaining battery level of your helmet. You can read more about that here.
