practice no reports exist to suggest anyone ever having ex-
perienced interference. We cannot however issue an offi cial
guarantee on our products’ suitability with all pacemakers
or other implanted devices due to the variety of devices
available. If you have any doubts, or if you experience any
unusual sensations while using Polar products, please
consult your physician or contact the implanted electronic
device manufacturer to determine safety in your case.
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 on page 65. To avoid any skin reaction to the
transmitter, wear it over a shirt. However, moisten the shirt
well under the electrodes to ensure fl awless operation.
Note: 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.
Training equipment with electronic components may
cause interfering stray signals. To tackle these problems,
try the following:
1. Remove the transmitter from your chest and use the
training equipment as you would normally.
2. Move the wrist unit around until you fi nd an area in
which it displays no stray reading or does not fl ash 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 unit in this interference-free area as much as
possible.
If the CS200 still does not work, the piece of equip-
ment may be electrically too noisy for wireless heart rate
measurement.
