2.2 Start Exercise and View Data
When starting to exercise, have your students stay
at least 3 feet / 1 meter apart to allow the wrist unit to
lock onto its wearer’s heart rate signal. This helps
minimize interference when the students come close
together during exercise. For further information on
interference, see chapter 8 Precautions.
Advise your students to press the RED button to record
exercise data. The heart rate and a framed heart
symbol
will appear in a few seconds.
The frame around the heart symbol indicates the
heart rate is coded.
A heart symbol without a frame indicates a
non-coded heart rate transmission. Heart rate
measurement functions also in non-coded mode,
especially if there are no sources of interference
nearby.
Note: If the display reads 00/--, heart rate is not being received.
Have your students bring their wrist units up to their chest near
the transmitter’s Polar logo. The wrist unit starts searching for
the heart rate signal again. The display refreshes in about
5 seconds.
