The Life Fitness Cross-Trainer is equipped with Polar
®
heart rate monitoring system in which electrodes, pressed against the
skin, transfer heart rate signals to the console. These electrodes are attached to a chest strap that the user wears during the
workout. The chest strap is optional. To order it, call Life Fitness Customer Support Services. See Section 6.4, titled
How to
Obtain Product Service
.
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 electrical impulses of the heart back to the receiv-
er. Moisten the electrodes. Then, secure the strap as high under the chest 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 electrodes are in direct contact with skin. However,
it also functions properly through a thin layer of wet clothing.
If it becomes necessary to re-moisten the chest strap electrodes, grasp the center of the strap, pull it away from the
chest to expose the two electrodes, and moisten them.
NOTE: If the Lifepulse system sensors are grasped while the chest strap is worn, and if the signals from the sensors
are valid, the on-board computer uses the sensor signals for calculating the heart rate instead of those transmitted with
the chest strap.
