Precautions
USING A POLAR HEART RATE MONITOR
IN A WATER ENVIRONMENT
Polar Heart Rate Monitors are water resistant to 20 meters. To
maintain the water resistance, do not operate the buttons of
the Polar wrist receiver under water.
Heart rate measurement in a water environment is technically
demanding for the following reasons:
• Pool water with a high chlorine content and seawater may
be very conductive and the electrodes of Polar transmitter
may get short circuited and ECG signals cannot be
detected by the transmitter unit.
• Jumping into the water or strenuous muscle movement
during competitive swimming may cause water resistance
that shifts the transmitter on the body to a location where it
is not possible to pick up ECG signal.
• The ECG signal strength varies depending on the individual’s
tissue composition and the percentage of people who have
problems in heart rate measuring is considerably higher in a
water environment than in other use.
POLAR HEART RATE MONITOR AND INTERFERENCE
ELECTROMAGNETIC INTERFERENCE
Disturbances may occur near high voltage power lines,
televisions, cars, wireless bike computers, some exercise
equipment or cellular phones.
CROSSTALK
The Polar wrist receiver in non-coded mode of operation picks
up transmitter signals within 1 metre/ 3 feet. Therefore, make
sure no other transmitter is within that range.
BATTERIES
POLAR CODED TRANSMITTER
The estimated average battery life of the Polar Coded
Transmitter is 2500 hours of use. Contact your distributor/
dealer for a Transmitter replacement. Service for
detailed instructions.
Polar recycles used Transmitters.
POLAR SmartEdge RECEIVER
The estimated average battery life of the Polar SmartEdge
receiver is 1 year in normal use (2h/day, 7 days a week).
However, because the battery is inserted at the factory, the
actual life of your first battery once in your possession may be
less than the estimated battery life. Note also that excessive
use of the backlight and the alarm signals will use the battery
more rapidly.
Do not open the Polar wrist receiver yourself. To ensure the
water resistance properties and the use of qualified
components, the wrist receiver battery should be replaced
only by a person authorised by Polar Electro Oy. At the same
time a full periodic check of the Polar Heart Rate Monitor will
be done. Service for detailed instructions.
