Why can't I measure speed?
When using a speed (cadence) sensor (ISC-12), if the wheel magnet moves so that it is not facing the sensor zone, the computer registers the speed signal as 0 and measurement is not possible. (This is because the speed signal from the sensor has priority over GPS when measuring speed.)

Why is the sensor or DI2 system signal not being received?
Try the following solutions.
• Press the RESET button on any sensors that cannot be connected.

Have you paired the sensor or DI2 system?
• You must use Cateye Cycling™ to pair the sensor or the DI2 system.
