From the main page of the Ride App, you can advance to the Settings menu.
Enable Auto Pause - with auto pause enabled, your Ride will pause from being recorded when the watch detects that your speed is zero.
High Contrast - when enabled, the screen background will turn white, which generally makes the watch screen more visible in bright sunlight. Note that when High Contrast mode is enabled, it will reduce the watch battery life.
Heart Rate Source - allows you to select the sensor source for heart rate measurements. See article Configure External Heart Rate Sensor for more information on how to configure the heart rate sensor.
