Owner’s Manual: Heart Rate Features 15
Wearing a Chest Strap
During a workout, the heart rate features appear on the
display when you wear a chest strap. To receive an accurate
reading, the chest strap needs to be in direct contact with
your skin.
1. Carefully dampen the back of the strap with tap water
Refer to Diagram 8.
Note: Do not use deionized water. It does not have the
proper minerals and salts to conduct electrical impulses.

2. Adjust the strap and fasten it around your chest. The strap
should feel snug, not restrictive. Refer to Diagram 9.

horizontally across your chest, and is centered in the
middle of your chest. Refer to Diagram 10.

After you put on the chest strap, face the display console for
a few seconds. This allows the receiver in the console to
recognize the signal from the chest strap.
