Technical Specification; M450 - Polar Electro M450 User Manual

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 in
any skin reaction, stop using the product and consult your physician. Also inform Polar Customer Care
about your skin reaction. To avoid any skin reaction to the heart rate sensor, wear it over a shirt, but
moisten the shirt well under the electrodes to ensure flawless operation.
The combined impact of moisture and intense abrasion may cause color to come off the
heart rate sensor's surface, possibly staining light-colored clothes. It may also cause a darker
color to come off clothing, possibly staining lighter-colored training devices. To keep a light-
colored training device glowing for years to come, please make sure the clothing you wear
while training does not bleed color. If you use perfume or insect repellent on your skin, you
must ensure that it does not come into contact with the training device or the heart rate
sensor. If you train in cold conditions (-20 °C to -10 °C / -4 °F to 14 °F) we recommend that
you wear the training device under the sleeve of your jacket, directly on your skin.
