Precautions - Polar Electro Accurex Plus User Manual

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 ACCUREX PLUS RECEIVER
The estimated average battery life of the Polar Accurex Plus
receiver is 1 year in normal use (1h/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.

PRECAUTIONS

POLAR HEART RATE MONITOR IN A
WATER ENVIRONMENT
Polar Heart Rate Monitors are water resistant to 20 metres. 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 a 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 the ECG signal.
• The ECG signal strength varies depending on the individual's
tissue composition. The percentage of people who have
problems in heart rate measuring is considerably higher in a
water environment than in other use.
