The process of pairing your head unit (Garmin, o-synce, etc..) is a little bit different than normal. Because there are no magnets installed to activate the crankset, load much be placed on the crank arm to activate the strain gauges.
After you have successfully updated your crank to RevUp firmware, place load on the crank arms to ensure they are active and ready to pair. Be sure you put your body weight on the pedals to apply load. Just using your hands/arms may not be enough to activate.
- Once load has been applied to your InfoCrank, go to your head unit pairing settings to search for your InfoCrank ANT+ signal.
