How To... REPLACE THE DIGITAL HEART RATE SENSORS (LC9500HR)
Tools Required: Phillips screwdriver, standard screwdriver, 5/64" hex key wrench
NOTE: The kit you have received will come equipped with either 5/64" hex key button head screws or
Phillips head pan screws. Either can be used for sensor replacement procedures on all models of Life
Fitness exercise equipment equipped with Lifepulse digital heart rate sensors. The treadmill handlebar
shown in the photographs are for demonstration purposes only. Replacement procedures as listed will
remain the same for all applications. ALWAYS REPLACE BOTH SETS OF SENSORS PROVIDED IN THE KIT.
Removing the existing Lifepulse digital heart rate sensors:
1. Using a standard flat screwdriver, pry off the stainless steel sensor
furthest away from you as if you were the user gripping the Lifepulse
heart rate monitoring sensors (if screw access holes are already provided
in the sensor you wish to replace, simply remove the two screws and
continue to Step 2). This will be the sensor on which your fingertips rest
during use. This sensor will be referred to as the "ground sensor" (black
or green wire) hereafter in these instructions. The sensor closest to the
user, on which the palm rests, will be referred to as the "signal output
sensor" (red or white wire).
2. Pull the ground sensor gently away from the molded plastic
housing, to which it was attached, to reveal a wire harness (black
or green wire) with a Faston connector attached to the back of
the sensor. Unplug the Faston connector from the ground
sensor.
3. Loosen and remove the two screws securing the two sensor
molded plastic housings to each other on the assembly. Lift the
molded plastic housings away from each other and unplug the
Faston connector attached to the back of the signal output
sensor (red or white wire).
