A. BasicUse is the easiest way to start exercising because you do not have to set different target limits or timers. You just start in Measuring mode and choose BasicUse and you are ready to go. You can select among several different heart rate, running or cycling information alternatives for the display of your wrist unit.

B. Freely programmable BasicSet offers you the possibility to set three functions to control your exercise session.

1.Three adjustable target limits (either HR, % of HRmax or Pace limit types)

2.Three adjustable alternating timers.

3.Time-based or heart rate-based recovery calculation. By using these functions, you can easily control your normal exercise session. You can program several different kinds of exercise sets. When training, choose the one that suits the training you plan to do best.

C.Freely programmable Interval Trainer automatically guides you through your interval training session. You can program the following exercise phases:

1. warm-up period with target limits and a countdown timer

2. up to 30 intervals with target limits and an option for a recovery calculation after each interval

3. a cool-down period, using a countdown timer after intervals

Use of this Interval Training function leaves you free to concentrate on your exercise during the interval training. Your wrist unit takes care of observing timers and limits, all you have to do is exercise.

4.FILE (SEE SECTION D. HOW TO RECALL TRAINING INFORMATION)

In this mode you can recall your training information. Your wrist unit saves up to 99 files of exercise information when you use the Recording mode (stopwatch on). For more information about the recorded training information, see chapter D. How to Recall Training Information.

5.OPTIONS (SEE SECTION B. HOW TO ENTER SETTINGS)

In the Options mode you set all your personal settings for optimal use of your running/cycling computer. It is highly recommended that you enter all your personal settings in your wrist unit before you start to use your running/cycling computer for the first time. By doing so, you guarantee the optimal functioning of your running/cycling computer. You can also use the Polar Precision Performance software to set and transfer your personal settings from your PC to your wrist unit.

6.TESTS (SEE SECTION E. TESTS)

In this mode you can carry out the Polar Fitness and OwnOptimizer™ Tests.

Polar Fitness Test estimates your maximal aerobic power (VO2max) and shows the result as a Polar OwnIndex value. This test also provides a predicted maximum heart rate value (HRmax-p). The Polar Fitness Test is designed to monitor your personal progress. You should do the test regularly to see the changes in your cardiovascular fitness. Your wrist unit will memorize your last OwnIndex value.
