The chest strap and the adjustable rubber strap must be put on as displayed. Adjust the
length so that the strap is tight but does not negatively affect your breathing or blood
circulation.
The two long contact surfaces of the chest strap (the two rubber surfaces with striped
pattern) must touch the skin directly. No material must be between the contact surfaces
and your skin.
As is the case with any material that comes into direct contact with your skin, there might
be skin irritations or allergic responses (e.g. redness, rash, etc.).
If you experience such changes on your skin, take off the chest strap immediately.
Wash the affected skin area with lukewarm water and mild soap and consult a doctor.
Regularly clean the contacts of the chest strap. Use a cloth moistened with lukewarm
water. Carefully dry the chest strap.
The transmission of the heart rate signal can be disturbed by mobile
telephones, electronic exercise equipment, wireless bicycle computers,
high-voltage power lines or other wireless devices.
