The timeout settings affect how long your device stays in training mode, for example, when you are waiting for a race to start. Hold MENU, select Settings > Activities & Apps, select an activity, and select the activity settings. Select Power Save Timeout to adjust the timeout settings for the activity.

Normal

Extended
