Preparation before measurement



• Smartphone use

When measuring, turn the smartphone display off, and with Cateye Cycling™ running, store the smartphone in a safe place such as a bag or pocket.

As measurement start/pause/resume and reset operations (finish trip) can be performed remotely from smart computer, there is no need to take out your smartphone until you want to save or upload trips.

* Cateye Cycling™ can measure even when running in the background.

• Restrictions on measurement

In Mirror Mode, the maximum elapsed time that can be measured is approximately 27 hours and maximum trip distance is 1000 km [620 mile]. When either of these values is exceeded, measurement finishes and trip data is saved temporarily.

In this case, the display returns to the [ready] (measurement standby) screen ready to start the next trip measurement.
