Operation Manual

3. If you have activated an optional sensor for the sport profile, the
training computer will automatically search for the signal.
4. The check mark indicates that the signal is found. If the training
computer does not find the signal, the display shows a triangle with
an exclamation mark.
Do not use the backlight during sensor search. The sensor search does
not operate when the backlight is on.
5. Once the training computer has found all the signals, press OK.
Recording started is displayed and you can start training.
During training recording you can change the training view by
browsing with UP/DOWN. To change settings without stopping the
training recording, press and hold LIGHT to enter QUICK MENU. For
more information, see Quick menu (page 32).
*Optional sensors include Polar s3+ stride sensor, Polar G5 GPS sensor / Polar G3 GPS sensor W.I.N.D.,
Polar CS speed sensor W.I.N.D. or Polar CS cadence sensor W.I.N.D.
"XX sensor low battery" is displayed during training if any of the possible sensors have low battery.
Train With Polar ZoneOptimizer
The ZoneOptimizer function determines your personalized sport zones (heart rate zones) for your aerobic
training session. It measures your heart rate variability during the warm-up and determines your personal
sport zones. For more information, see Polar ZoneOptimizer (page 41).
To use the ZoneOptimizer function in your training, set in on by selecting MENU > Settings > Heart rate
settings > ZoneOptimizer > On .
The ZoneOptimizer function defines the personalized target heart rate zones for you in the beginning of
every training session. If there is less than an hour since your last ZoneOptimizer definition, the given
target heart rate zones are not necessarily valid, because you may have not recovered from previous
training, and during instant recovery, heart rate variability returns to normal state slower than heart rate.
Start Training Session with Polar ZoneOptimizer
Before ZoneOptimizer determination, make sure that you have the Polar default sport zone heart rate
limits in use i.e. you have not modified the heart rate limits manually. If you want to modify the Sport
Zone heart rate limits manually, set the ZoneOptimizer function off.
To set the ZoneOptimizer function on, select MENU > Settings > Heart rate settings > ZoneOptimizer > On.
The ZoneOptimizer determination will start in the background already when you are in pre-training mode.
When you see the ECG-curve on the top right hand corner on the display, you will know that the heart rate
measurement and ZoneOptimizer are on.
