To use the treadmill's Lifepulse
steel sensors on the Ergo
Contact must be maintained with all four sensors to obtain a heart rate. The console displays a heart
rate within 20 to 30 seconds of contact with the sensors.
Do not attempt to grasp the sensors at speeds above 4.5 MPH, or 7.2 KPH. For these speeds, the
use of a heart rate chest strap is recommended.

The Life Fitness Treadmill is equipped with Polar
electrodes, pressed against the skin, transfer heart rate signals to the treadmill console. These electrodes
are attached to a chest strap that the user wears during the workout.
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 its most accurate heart rate reading when the electrodes are in direct
contact with bare skin. However, it will function with a slightly less accurate heart rate reading 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 re-moisten them.
During the setup of a heart rate zone training workout, the user will be required to enter a start-up
speed. If a heart rate chest strap is not detected, the maximum allowable speed is 4.5 mph. If a heart
rate chest strap is detected, the maximum speed is 12 mph.
