Many Riders start their new season with new batteries regardless of the current battery level.  With the magnets now optional when riding, a problem has been arising with some people forgetting that the magnet (supplied) is still used to switch the cranks from "computer" mode to operating mode.

When you install new batteries, in cranks numbered below about 3200, you will see a flashing light that continues for some time.  That indicates that the batteries are installed and the InfoCrank® is now in computer mode.  Waving a magnet across the rear RF cover will switch the mode to operating.   Your cranks are ready to go now.  For precautionary reasons, before first use, do a zeroing on your head unit - often called calibration.  

For cranks numbered after about 3200, you will not see a blinking light - if you were quick you will have noticed one flash as the batteries made contact.  Your cranks should be ready to go as soon as the battery cover is tightened.  If they will not pair immediately with your head unit or the VINC app, then wave a magnet across the RF cover.  

Remember to use SR44 batteries.  Batteries are available from Verve.  Many brands are quite accessible in shops locally, though we find Renata and Varta the most reliable.  Always buy from a large vendor who is likely to have good turn over.  You don't want batteries that were manufactured years ago and have been sitting on a shelf losing power for ages.

  1. Install batteries gently with flat surface facing outwards
  2. Replace the battery cover with light tube facing upright compared to the etched “INFOCRANK” on each crank (see the pic below).
  3. Green light flashes once (latest software) or fast flashing (older software).
  4. Latest software does not require magnets to return to operating mode. Older software (pre-2018 generally) required magnet waved across the RF or battery cover until the flashing light stops.  Then the cranks are ready for use.
  5. Finally, do a zeroing using the VINC app or your head unit.  Zero’ing is complete when the result is “0”.
