Thoroughly rinse the device with fresh water after exposure to chlorine, salt water, sunscreen, cosmetics, alcohol, or other harsh chemicals. Prolonged exposure to these substances can damage the case. Do not store the device where prolonged exposure to extreme temperatures can occur, because it can cause permanent damage. Cleaning the Device 1 Wipe the device using a cloth dampened with a mild detergent solution. 2 Wipe it dry. Caring for the Heart Rate Monitor NOTICE A build up of sweat and salt on the strap can decrease the ability of the heart rate monitor to report accurate data. • Rinse the strap after every use. • Hand wash the strap occasionally, using a tiny amount of mild detergent, such as dishwashing liquid. NOTE: Using too much detergent may damage the strap. • Do not put the strap in a dryer. • When drying the strap, hang it up or lay it flat.
