The combined impact of moisture and intense abrasion may cause color to come off the heart rate
sensor’s surface, possibly staining clothes. If you use perfume, suntan/sunscreen lotion 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. Please avoid clothing with colors that might transfer onto the training device (especially training
devices with light/bright colors) when worn together.
