3.2 HEART RATE MONITORING
THE POLAR®TELEMETRY HEART RATE MONITORING CHEST STRAP
The Life Fitness stairclimber is equipped with Polar telemetry (optional on the 90S model),
a heart rate monitoring system in which electrodes, pressed against the skin, transfer heart rate
signals to the stairclimber console. These electrodes are attached to a chest strap that the user
wears during the workout. To order the optional telemetry feature for the 90S, or the Polar heart
rate chest strap for either model, 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 receiver. 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.
