3.2 Heart Rate Monitoring
The Lifepulse™ Digital Heart Rate Monitoring System
The patented Lifepulse system sensors are the built-in heart rate monitoring system on the Life Fitness Cross-Trainer.
For the most accurate reading possible, during a workout:
• Grasp the sensors (A) firmly.
• Hold each sensors at the vertical midpoint.
• Keep hands steady and in place.
The console displays the heart rate within 10 to 40 seconds after the user grasps the sensors. The following factors may
affect a Lifepulse reading: incorrect hand placement on the sensors, upper body activity, lotion or dirt on hands, and
excessive or insufficient pressure used when gripping the sensors.
The Optional Polar® Telemetry Heart Rate Chest Strap
The Life Fitness Cross-Trainer is equipped with Polar® telemetry, a heart rate monitoring system in which electrodes,
pressed against the skin, transfer heart rate signals to the console. These electrodes are attached to a Polar telemetry
heart rate chest strap that the user wears during the workout. The Polar telemetry heart rate chest strap is optional.
Contact Life Fitness Customer Support Services to order.
See the diagram below for correct positioning of the Polar telemetry heart rate chest strap. The electrodes (A), which
are the two grooved surfaces on the underside of the strap, must remain wet to transmit accurately the electrical im-
pulses of the heart back to the receiver. Moisten the electrodes. Then, secure the Polar telemetry heart rate chest 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 Polar
telemetry heart rate chest strap electrodes, grasp the center of the strap, pull it away from the chest to expose the two
electrodes, and re-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
Polar telemetry heart rate chest strap.
