Notice to persons with pacemakers, defibrillator or other
implanted electronic device. Persons who have a pacemaker use the
Polar heart rate monitor at their own risk. Before starting use, we always
recommend an exercise test under doctor’s supervision. The test is to ensure
the safety and reliability of the simultaneous use of the pacemaker and the
heart rate monitor.
If you are allergic to any substance that comes into contact with
the skin or if you suspect an allergic reaction due to using the
product, check the listed materials in the "Technical Specifications"
chapter. To avoid any skin reaction risk with the transmitter, wear it over a
shirt. However, moisten the shirt well under the electrodes to ensure
flawless operation.
The combined impact of moisture and intense abrasion may cause a
black color, which might stain light-colored clothes especially, to come
off the transmitter's surface.
