    Press MODE for 1 second to resume measurement.

  • 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 signal not being received?

    Try the following solutions.

    • Press the RESET button on any sensors that cannot be connected.

    ​

    Have you paired the sensor?

    • You must pair smart computer with your smartphone via Cateye Cycling™.

  • Why can't I measure without a speed sensor?

    You may have to wait a little longer after starting measurement.

    • Your smartphone may take a while to acquire GPS in some cases.
    Wait somewhere outdoors for a while before starting.

    * The time it takes to acquire GPS will depend on your smartphone.

    ​

    The location or weather may not be appropriate for acquiring a GPS signal.

    • If your smartphone's GPS connection is lost, smart computer can no longer perform measurement.

    * For information on how to acquire a GPS signal, refer to your smartphone instruction manual.

  • Location information is not obtained via GPS and routes are not being recorded

    Is the smartphone's clock accurate?

    • If the smartphone system clock is not correct, GPS information will not be obtained.
