Polar Electro F11 User Manual page 39

If you have a pacemaker, defibrillator or other
implanted electronic device, you use the Polar
heart rate monitor at your own risk. Before starting
use, take a maximal exercise stress test under the
supervision of a physician. 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.
