M. POLAR GLOSSARY
Activity level: A personal
assessment of your long term
physical activity level that is used in
the Polar Fitness Test.
Altitude and temperature: The
altitude and temperature are
measured by using an atmospheric
pressure sensor. Air pressure
changes constantly due to various
weather conditions and therefore
the calculated altitude of a certain
spot may differ. Variation of high
and low pressure or air conditioning
can cause a change in the altitude
reading. For example, a
thunderstorm can cause a change of
up to 80 mbars, which means a
change of approximately 2000 ft/
700 m in the calculated altitude.
Therefore, it is recommended that
you adjust the exact starting point
altitude whenever a reliable
reference; for example, a peak
pointer or a map, is available. It is
also recommended that you check
the altitude of your house and
other common starting points for
training.

Coded heart rate transmission:
Polar coded transmitter
automatically locks in a code to
transmit your heart rate to the wrist
receiver. In a coded transmission the
receiver accepts heart rate data only
from the Polar coded transmitter.
Coding significantly reduces
crosstalk caused by other users of
heart rate monitors. However, it
does not necessarily reduce all
environmental interference.
Electrodes: The grooved areas of
the transmitter that rest against the
skin and pick up the EKG signal.
Maximal oxygen uptake:
(maximal aerobic power, VO
) Is
2max
the maximal rate at which oxygen
can be used by the body during
maximal work. VO
is a good
2max
index of aerobic fitness.
Maximum heart rate: (HR
) Is
max
the highest number of heart beats
per minute of a person.
Target heart rate zone: The area
between the upper and lower
target heart rate limits. Target zone
selection is based on personal
fitness goals.
Display Symbols
Indicates an ongoing heart rate measurement and flashes to the beat of
your heart.
Indicates there has not been heart rate reception for less than 5 seconds.
- - Indicates there is no heart rate reception. Bring the wrist receiver up to
your chest near the transmitter's Polar logo.
The receiver starts looking for the heart rate signal again.
Options mode: indicates that you are setting the bike functions
Exercise mode: indicates that bike 1 or 2 is on.
File mode: indicates cycling information.
In the Time of Day display the alarm is on.
Measure mode: beeps if you are exercising outside your target heart rate
zone. Fitness Test mode: sounds an alarm at the end of the fitness test.
Indicates the Interval Trainer.
Indicates continuous interval (Cont).
Exercise mode: indicates the heart rate above the target zone.
Exercise mode: indicates the heart rate below the target zone.
