How to prepare the wrist unit
1. Since the display is blank when the wrist unit leaves the
factory, you have to activate the wrist unit by pressing the
OK button twice, after which the Time of day display
appears. This is a one-off procedure; once you have turned
on your wrist unit you can not turn it off anymore.
2. You may start measuring your heart rate right away
using the default settings. However, the following
settings are ones that it would be useful to change as
soon as possible: Time of day (see section Setting the
watch) and personal user settings (see section User
information settings).
3. Your heart rate monitor has various functions that you can
use according to your personal training needs. For more
information, see section All that you can do with your
Heart Rate Monitor. You can either manually enter the
settings by pressing the wrist unit buttons or you can
define your settings with Polar Precision Performance
software, after which the data should be transferred from
your PC to the wrist unit.
4. Wear the wrist unit as you would wear an ordinary
watch. When you go biking, we recommend attaching the
wrist unit to the Polar Bike Mount™.
