A-Gps Expiry Date; Gps Features; Back To Start - Polar Electro M430 User Manual

A-GPS EXPIRY DATE

The A-GPS data file is valid for up to 13 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 M430. In M430, go to Settings >
General settings > About your product > A-GPS exp. date. If the data file has expired, sync your M430 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 the current position.

GPS FEATURES

M430 includes the following GPS features:
•
Altitude, ascent and descent: Real-time altitude measurement, as well as ascended and descended
meters/feet.
•
Distance: Accurate distance during and after your session.
•
Speed/Pace: Accurate speed/pace information during and after your session.
•
Running index: In M430, Running Index is based on heart rate and speed data measured during the run.
It gives information about your performance level, both aerobic fitness and running economy.
•
Back to start: Directs you to your starting point in the shortest distance possible, as well as shows the
distance to your starting point. Now you can check out more adventurous routes and explore them safely,
knowing that you're only a touch of a button away from seeing the direction to where you started.
•
Power save mode: Allows you to save the battery life of your M430 during long training sessions. Your
GPS data is stored at intervals of 60 seconds. A longer interval gives you more recording time. When
power save mode is on, automatic pause cannot be used. In addition, Running Index cannot be used
unless you have a stride sensor.
For best GPS performance, wear M430 on your wrist with the display facing up. Due to the location of the
GPS antenna on the M430, it is not recommended to wear it with the display on the underside of your wrist.
When wearing it on the handlebars of a bike, make sure the display is facing up.
