Note that in addition to exercise intensity,
medications for heart conditions, blood pressure,
psychological conditions, asthma, breathing, etc.,
as well as some energy drinks, alcohol, and
nicotine may also affect heart rate.
It is important to be sensitive to your body's
responses during exercise. If you feel unexpected
pain or excessive fatigue when exercising, it is
recommended that you stop the exercise or
continue at a lighter intensity.
Notice to individuals with pacemakers,
defibrillators or other implanted electronic
devices. Individuals who have a pacemaker use
the Polar running computer at their own risk.
Before starting use, we always recommend a
maximal exercise stress test under a doctor's
supervision. The test is to ensure the safety and
reliability of the simultaneous use of the
pacemaker and the Polar running computer.

To avoid any skin reaction to the transmitter, wear
it over a shirt, but moisten the shirt well under the
electrodes to ensure flawless operation.
Your safety is important to us. The shape of the
foot pod/stride sensor is designed to minimize the
possibility of it getting caught in something. In
any case, be careful when running with the foot
pod/stride sensor in brushwood, for example.
The combined impact of moisture and intense
abrasion may cause a black color to come off the
transmitter's surface, possibly staining
light-colored clothes. If you use insect repellent
on your skin, you must ensure that it does not
come into contact with the transmitter.
