ACTIVITY BENEFIT

Activity benefit gives you feedback on the health benefits that being active has given you, and also on what kind of
unwanted effects sitting for too long has caused to your health. The feedback is based on international guidelines and
research on the health effects of physical activity and sitting behavior. The core idea is: the more active you are, the
more benefits you get!
Both the Flow app and Flow web service show the activity benefit of your daily activity. You can view the activity benefit
on daily, weekly and monthly basis. In the Flow web service, you can also view the detailed information on health
benefits.
For more information, see 24/7 Activity Tracking.

POSITIONING SATELLITES

Your watch has built-in GPS (GNSS) that provides speed, pace, distance and altitude measurement for a range of
outdoor sports, and allows you to see your route on map in the Flow app and web service after your session. The watch
uses GPS, GLONASS, Galileo, BeiDou and QZSS systems simultaneously for maximum accuracy around the globe. By
default, the watch also utilizes dual-frequency GPS for improved positioning accuracy especially in difficult use
conditions. Alternatively, you can use a power-saving single-frequency GPS mode on your watch. Single-frequency GPS
mode does not give as accurate results in difficult use conditions, but it will improve the battery lifetime during exercise.
The setting is located in General settings > Positioning satellites. Choose Better accuracy (dual-frequency GPS) or
Power save (single-frequency GPS).

ASSISTED GPS

The watch uses Assisted GPS (A-GPS) to acquire a fast satellite fix. The A-GPS data tells your watch the predicted
positions of the GPS, Glonass, Galileo, BeiDou and QZSS satellites. This way the watch knows where to search for the
satellites and thus makes defining your initial location faster and improves the accuracy of the positioning data.
The A-GPS data updates once a day. The latest A-GPS data file is automatically updated to your watch each time you
sync it with the Flow web service via FlowSync software or via the Flow app.

A-GPS expiry date

The A-GPS data file is valid for up to 14 days. Positioning accuracy is relatively high during the first three days, and
progressively decreases during the remaining days. Regular updates help to ensure a high level of positioning accuracy.
You can check the expiry date for the current A-GPS data file from your watch. Go to Settings > General settings >
About your watch > Assisted GPS expires. If the data file has expired, sync your watch with the Flow web service via
FlowSync software or with the Flow app to update A-GPS data.
Once the A-GPS data file has expired, more time may be required for acquiring your current position and the positioning
data accuracy may decrease.
