3.2 Heart Rate Monitoring

The Lifepulse Digital Heart Rate Monitoring System
TM
The patented Lifepulse system sensors (B) are the built-in heart rate
monitoring system on this product. For the most accurate reading
possible, during a workout:
Grasp the sensors firmly.
ƒ
Hold each sensors at the midpoints.
ƒ
Keep hands steady and in place.
ƒ
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:
ƒ incorrect hand placement on the sensors,
ƒ upper body activity, lotion or dirt on hands, and
ƒ excessive or insufficient pressure used when gripping the
sensors.
The Optional Polar
The Polar telemetry heart rate monitoring system transfers heart rate signals to the console when electrodes are
pressed against the skin. 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 Ser-
vices to order.
See the diagram to the right of this paragraph for correct position-
ing 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 impulses 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 func-
tions 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 these sensor signals for calculating the heart rate instead of those transmitted by the
Polar telemetry heart rate chest strap.
