The patented Lifepulse system sensors are the built-in heart rate monitoring system on these products. For the most
accurate reading possible, during a workout:
•
Grasp the sensors firmly.
•
Hold each sensors at the 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 ex-
cessive or insufficient pressure used when gripping the sensors.
Note (treadmills only):
Do not attempt to grasp the sensors at speeds above 4.5 mph or 7.2 kph. For these speeds, the
use of a Polar telemetry heart rate chest strap is recommended.

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 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 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. How-
ever, 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 these sensor signals for calculating the heart rate instead of those transmitted by the
Polar telemetry heart rate chest strap.
Note (treadmills only):
During the setup of a heart rate zone training workout, the user will be required to enter a start-up
speed. If a Polar telemetry heart rate chest strap is not detected, the maximum allowable speed is 4.5 mph. If a Polar
telemetry heart rate chest strap is detected, users can workout at the maximum allowed speed set in Manager’s Configu-
ration.
