IR Compensation
NOTE: This procedure is required after replacing the lower control board or the drive motor.
Tools Required
• Phillips head screwdriver
• Plastic (or non-conductive), flat head screwdriver
1. Please read instructions thoroughly before performing this procedure.
2. Remove the motor cover.
A. Using a Phillips head screwdriver, loosen three screws on each motor cover side (left
and right). See Figure 2.
B. Lift the motor cover center up and off the treadmill. The screws will stay in place. See
Figure 2.
3. Perform the IR compensation procedure.
A. Enter Test Mode by pressing and holding down any key on the display while turning
the power switch to the on (I) position. When the key is released “TEST” and the
software revision “rx.x” are shown on the display.
B. While standing on the ground, press Start and then press the Speed Up key once to
set the treadmill speed to 1.0 mph (1.6 kph).
! WARNING: Do not touch components on the lower board. A charge can remain after
unplugging the power cord and turning off the treadmill.
! CAUTION: The belt will be jerky during the next step. Hold the handrail to support
yourself.
C. Hold on to the handrails as you step on the running belt, begin walking and notice how
the belt feels, (the belt may surge, vibrate or slack).
NOTE: If the belt doesn't need to
be adjusted skip to step 4A.
D. Pull up on the lower board shield. It will snap out. NOTE: Newer versions of the shield
will have a hole directly over the IR compensation. If you have the new shield, place the
plastic screwdriver through the hole to adjust the IR compensation instead of removing
the shield.
E. Locate the control called “IR COMP” on the lower board. NOTE: DO NOT use a metal
screwdriver. DO NOT adjust the other two controls that look identical to the IR
COMP control.
