Wear the optional Polar
puter to monitor the heart rate during a workout. The computer automatically adjusts the incline level to maintain the
target heart rate based on the actual heart rate.
The Optional Polar Telemetry Heart Rate Chest Strap
®
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 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. 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 these sensor signals for calculating the heart rate instead of those transmitted by
thePolar telemetry heart rate chest strap.
Note: During the setup of a heart rate zone training workout, the user will be required to enter a start-up speed. If a Po-
lar telemetry heart rate chest strap is not detected, the maximum allowable speed is 4.5 mph / 7.2 kph. If a Polar telem-
etry heart rate chest strap is detected, users can workout at the maximum allowed speed set in Manager's Configuration.
The Lifepulse 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
ƒ Hold each sensors at the midpoint.
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:
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.
ƒ
Note: Do not attempt to grasp the sensors on a treadmill 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.
