ENGLISH
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, stop or
continue at a lighter intensity.
If you have a pacemaker, defibrillator or other
implanted electronic devices, use the Polar heart
rate monitor at your own risk. Before starting use,
take 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 heart rate monitor.
If you are allergic to any substance that comes
into contact with your skin or if you suspect an
allergic reaction due to using the product, check
the listed materials in Technical Specifications.
To avoid any skin reaction to the transmitter, wear
it over a shirt. Moisten the shirt well under the

electrodes to ensure flawless operation.
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, make sure
that it does not come into contact with the
transmitter.
When in non-coded mode, the wrist unit picks up
transmitter signals within 1 m / 3ft. The frame
around the heart symbol on the bottom of the
display indicates that transmission is coded.
Coding blocks interference from nearby heart rate
monitors.
