H EART R ATE C HEST S TRAP (M ODEL C7i ONLY )
The Lifecycle bike is equipped with Polar
® telemetry, a heart rate monitoring system in which electrodes, pressed
against the 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 standard with the bike.
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 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 center of the strap, pull it away from the
chest to expose the two electrodes, and moisten them.

The patented Lifepulse Digital Heart Rate Sensors are the built-in heart rate monitoring system on the Lifecycle C9i
exercise bike. During a workout, grasp two of the four stainless steel sensors that are set into the handlebars. The
console displays the heart rate after 10 to 40 seconds.
