3.2 HEART RATE MONITORING

THE POLAR® HEART RATE CHEST STRAP

The Life Fitness Treadmill is equipped with Polar® telemetr y, a heart rate monitoring system in which electrodes,
pressed against the the skin, transfer heart rate signals to the treadm ill console. These electrodes are attached to a
chest strap that the user wears during the workout. The chest strap is stand ard with the treadmill.
See the diagram below for correct positioning of the strap. The electrodes (A), which are the two grooved surfaces
on the underside of the strap, must remain wet to transmit accurately the elec trical impulses of the heart back to the
receiver. Moisten the electrodes. Then, secure the strap as high under the c hest muscles as possible. The strap
should be snug, but comfortable enough to allow for normal breathing.
The transmitter strap delivers an optimal heart rate reading when the elec trodes are in direct contact with bare skin.
However, it functions properly through a thin layer of wet clothing.
If it becomes necessary to re-moisten the chest strap electrodes, grasp the c enter of the strap, pull it away from the
chest to expose the two electrodes, and moisten them.
