TELEMETRY HEART RATE MONITORING CHEST STRAP
The Lifecycle exercise bike is equipped with Polar telemetry (optional on the 90C in the United
States), a heart rate monitoring system in which electrodes, pressed against the skin, transfer heart
rate signals to the bike 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 elec-
trical 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.
