Get Started
Charge it and switch it on
First charge
Plug the dock into any USB power source and place the sensor in it. Alignment matters less than contact. The sensor should sit flat in the dock recess.
While charging, the light pulses purple. When the battery is genuinely full it turns green. Give it around two hours from empty.
Switching it on
Give the button one short press. The light breathes red while the sensor starts up, then blinks red: it is recording. Switching it on starts a recording, so do it shortly before you ride. If it is sitting on the dock, it breathes purple and charges instead.
Switching it off
Hold the button until the light goes out, then let go. The sensor saves its data and switches off.
If you press the button and get three fading red pulses, the battery is too low to start. That is the sensor asking to be charged, not a fault. Put it on the dock for twenty minutes and try again.
For every light pattern the sensor can show, see what the light colours mean.
