Caring for the Heart Rate Monitor
You must unsnap and remove the module before washing the
strap.
A build up of sweat and salt on the strap can decrease the
ability of the heart rate monitor to report accurate data.
• Go to
www.garmin.com/HRMcare
instructions.
• Rinse the strap after every use.
• Machine wash the strap after every seven uses.
• Do not put the strap in a dryer.
• When drying the strap, hang it up or lay it flat.
• To prolong the life of your heart rate monitor, unsnap the
module when not in use.
Linking to Fitness Equipment
ANT+ technology links your heart rate monitor to fitness
equipment so you can view your heart rate on the equipment
console.
