Power save settings
The power save settings allow you to extend your training time by changing the GPS recording rate, setting wrist-based heart rate off and using the screen saver. These settings let you optimize battery usage and get more training time for extra long sessions or when the battery is running low.
The power save settings are found in the quick menu. You can access the quick menu from pre-training mode, during a session when paused and during transition mode in multisport sessions with the LIGHT button.
After setting on any of the power save settings, you'll see their effect on the estimated training time in pre-training mode. Note that the power save settings are set on for each session separately. The settings are not stored.
Note that the temperature affects the estimated training time. When training in cold conditions the actual training time can be less than what is indicated when starting the session.
GPS recording rate
Set the GPS recording rate to a less frequent interval (1 minute or 2 minutes). Handy in ultra-long sessions when long battery life is essential.
Note that changing the GPS recording rate to a less frequent interval may reduce the accuracy of other measurements, such as speed/pace and distance, depending on the sport profile and sensors used.
Wrist-based heart rate
Set wrist-based heart rate off. Set it off to save power when you don't necessarily need heart rate data. When using a heart rate monitor with a chest strap wrist-based heart rate is set off by default.
Set the screen saver on in sessions in which you don't need to view training data continuously.
When the screen saver is set on, only the time is shown on the display. Press any button to exit the screen saver and view your training data. The screen saver goes back on after 8 seconds.
