Precautions - Polar Electro E200 User Manual

G. PRECAUTIONS
Using the Polar E200 in a Water Environment
The Polar E200 is water resistant to 160 feet/50 meters.
Heart rate measurement in a water environment is technically
demanding for the following reasons:
• Pool and salt water can be very conductive and may short
circuit the electrodes so that EKG signals cannot be detected
by the transmitter.
• Jumping into the water or strenuous muscle movement during
competitive swimming may cause the transmitter to slip out of
place.
• The EKG 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.
Polar Heart Rate Monitor and Interference
Electromagnetic Interference
Disturbances may occur near high voltage power lines, traffic
lights, overhead lines of electric railways, electric bus lines or
trams, televisions, computers, cars, electric motors, bike
computers, some motor driven exercise equipment, cellular
phones, antennas, invisible fences, or when you walk through
electric security gates. Interference or "crosstalk" can also be
caused by the heart rate signal from another Polar HRM wearer.
Please see Chapter H, ´Frequently asked questions´ for possible
solutions.

Exercise Equipment
Several pieces of exercise equipment with electronic or electrical
components such as LED displays, motors and electrical brakes
may cause interference with the heart rate signal. To solve these
problems, relocate the Polar wrist receiver as follows:
1. Remove the transmitter from your chest and use the exercise
equipment as you would normally.
2. Move the wrist receiver around until you find an area in which
it displays no stray reading or flashing of the heart symbol.
Interference is often worst right in front of the display panel
of the equipment, while the left or right side of the display is
relatively free of disturbance.
3. Put the transmitter back on your chest and keep the wrist
receiver in this interference-free area as much as it is possible.
4. If the Polar heart rate monitor still does not work with the
exercise equipment, this piece of equipment may be
electrically "too noisy" for wireless heart rate measurement.
Minimizing Possible Risks in
Exercising with a Heart Rate Monitor
Exercise may include some risk, especially for those who have
been sedentary. Before starting a regular exercise program an
individual is recommended to answer to the following questions
for health status checking. If the answer is yes to any of the
questions, we recommend to consult a doctor before starting an
exercise program.
• Have you not exercised for the past 5 years?
• Do you have high blood pressure?
• Do you have high blood cholesterol?
• Do you have symptoms of any disease?
• Are you taking any blood pressure or heart medication?
• Do you have a history of breathing problems?
• Are you recovering from a serious illness or medical treatment?
• Do you use a pacemaker or another implanted electronic device?
• Do you smoke?
• Are you pregnant?
