Heart Rate Measurement; Maximum Heart Rate - Tunturi Pure Cross R 4.1 Mode D'emploi

Most accurate pulse measurement is
achieved when the skin is slightly moist
and constantly touching the hand pulse
sensors. If the skin is too dry or too
moist, the pulse rate measurement might
become less accurate.
NOTE
Do not use the hand pulse sensors in
combination with a heart rate chest belt.
If you set a heart rate limit for your
workout, an alarm will sound when it is
exceeded.

Heart rate measurement

(heart rate chest belt)
The most accurate heart rate
measurement is achieved with a
heart rate chest belt. The heart rate is
measured by a heart rate receiver in
combination with a heart rate transmitter
belt. Accurate heart measurement
requires that the electrodes on the
transmitter belt are slight moist and
constantly touching the skin. If the
electrodes are too dry or too moist, the
heart rate measurement might become
less accurate.
WARNING
If you have a pacemaker, consult a
physician before using a heart rate chest
belt.
CAUTION
If there are several heart rate
measurement devices next to each
other, make sure that the distance
between them is at least 2 meter.
If there is only one heart rate receiver
and several heart rate transmitters,
make sure that only one person with a
transmitter is within transmission range.
NOTE
• Do not use a heart rate chest belt
in combination with the hand pulse
sensors.
Owner's manual • Pure 4.1
• Always wear the heart rate chest belt
under your clothes directly in contact
with your skin. Do not wear the heart
rate chest belt above your clothes.
If you wear the heart rate chest belt
above your clothes, there will be no
signal.
• If you set a heart rate limit for your
workout, an alarm will sound when it
is exceeded.
• The transmitter transmits the heart
rate to the console up to a distance
of 1,5 meter. If the electrodes are not
moist, the heart rate will not appear
on the display.
• Some fibres in clothes (e.g. polyester,
polyamide) create static electricity
which can prevent accurate heart
rate measurement.
• Mobile phones, televisions and
other electrical appliances create
an electromagnetic field which
can prevent accurate heart rate
measurement.

Maximum heart rate

(during training)
The maximum heart rate is the highest
heart rate a person can safely achieve
through exercise stress. The following
formula is used to calculate the average
maximum heart rate: 220 - AGE. The
maximum heart rate varies from person
to person.
WARNING
Make sure that you do not exceed
your maximum heart rate during your
workout. If you belong to a risk group,
consult a physician.
