How to Prepare the Wrist Receiver
1. Since the display is blank when the receiver leaves the
factory, you have to activate the wrist receiver 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 receiver 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 Watch settings)
and personal user settings (see section User information
settings).
3. The receiver has various functions that you can use
according to your personal training needs. For more
information, see section Modes and their functions.
4. Wear the wrist receiver as you would wear an ordinary
watch. If you go biking, we recommend attaching the
wrist receiver to a Polar Bike Mount™.
