Pool Swimming
NOTICE
Hand wash the heart rate monitor after exposure to chlorine or other pool chemicals. Prolonged exposure to
these substances can damage the heart rate monitor.
The HRM-Pro accessory is designed primarily for open water swimming, but it can be used occasionally for
pool swimming. The heart rate monitor should be worn under a swim suit or triathlon top during pool
swimming. Otherwise, it may slide down your chest when pushing off the pool wall.
Caring for the Heart Rate Monitor
NOTICE
A buildup of sweat and salt on the strap can decrease the ability of the heart rate monitor to report accurate
data.
Rinse the heart rate monitor after every use.
Hand wash the heart rate monitor after every seven uses or one pool swim, using a tiny amount of mild
detergent, such as dishwashing liquid.
NOTE: Using too much detergent may damage the heart rate monitor.
Do not put the heart rate monitor in a washing machine or dryer.
When drying the heart rate monitor, hang it up or lay it flat.
Tips for Erratic Heart Rate Data
If the heart rate data is erratic or does not appear, you can try these tips.
Reapply water to the electrodes and contact patches (if applicable).
Tighten the strap on your chest.
Warm up for 5 to 10 minutes.
Follow the care instructions (Caring for the Heart Rate Monitor, page 33).
Wear a cotton shirt or thoroughly wet both sides of the strap.
Synthetic fabrics that rub or flap against the heart rate monitor can create static electricity that interferes
with heart rate signals.
Move away from sources that can interfere with your heart rate monitor.
Sources of interference may include strong electromagnetic fields, some 2.4 GHz wireless sensors, high-
voltage power lines, electric motors, ovens, microwave ovens, 2.4 GHz cordless phones, and wireless LAN
access points.
HRM-Swim Accessory
The device can record heart rate during your swim (Chest Heart Rate While Swimming, page 31).
Sizing the Heart Rate Monitor
Before your first swim, take some time sizing the heart rate monitor. It should be tight enough to stay in place
when pushing off the pool wall.
Select a strap extender, and attach it to the elastic end of the heart rate monitor.
The heart rate monitor comes with three extender straps to fit different chest sizes.
TIP: The medium strap extender works for most shirt sizes (from medium to extra-large).
Put on the heart rate monitor backward to easily adjust the slider on the strap extender.
Put on the heart rate monitor forward to easily adjust the slider on the heart rate monitor.
