3. DURING EXERCISE
Record Your Exercise
1. Wear the transmitter and wrist unit. Press
START to begin recording exercise data.
Preferably, there should be no other heart rate
monitors nearby (within 1m / 3ft), to avoid
interference.
2. Your heart rate and the framed heart symbol
will appear in a few seconds. The frame around
the heart symbol indicates that your heart rate
is coded. A heart without a frame indicates a
non-coded heart rate transmission.
3. To activate the heart rate zone alarm, press and
hold NEXT.
4. Press STOP to stop recording. SUMMARY is
automatically displayed. Each result is
displayed for 3 seconds.
If your display reads 00/-- , heart rate signal is not
being received. Bring the wrist unit up to your
chest near Polar logo. This will prompt the wrist
unit to begin a new search for the heart rate
signal.
