ICON CALIBRATION INSTRUCTIONS MC-70

1) Press the Stop and the Speed Up keys down while inserting the safety key. If this doesn’t work, email us at doc@treadmilldoctor.com for key sequence instructions to enter calibration.

2) Press the Stop key one time. The Time window should read EP:2P. This means that it passes the EPROM test.

3) Press either incline key and the incline will calibrate automatically.

4) BE CAREFUL, THE TREADMILL WILL RUN AT FULL SPEED IN THIS NEXT MODE! DO NOT STAND ON THE WALKING BELT. Press the Speed Up key and hold it down until 85 is shown in the Distance window.

5) If the top speed of the treadmill does not match the displayed speed on the computer console, adjust the max speed potentiometer on the motor control board.

6) The max speed potentiometer is a small black square with a white center and is located near the three small speed wire connections
labeled H, W, & L. Using a small insulated screwdriver adjust this potentiometer clockwise to speed up and counter-clockwise to slow
down the max speed of the treadmill. A tiny turn of this potentiometer will make a big difference in speed so be careful when making adjustments.

7) It is not important to get the speed set exactly at the max speed of the treadmill but do make sure to get the speed within .2 MPH of the max speed of the treadmill. For instance if the max speed of the treadmill is 10 MPH, make sure to have the speed set between 9.8
MPH and 10.2 MPH. Some models have a 12 MPH top speed, so please ask us if you aren’t sure.

8) THIS IS A VERY IMPORTANT STEP BECAUSE YOU WILL GET AN ERROR MESSAGE IF THIS STEP IS SKIPPED. After completing calibration of the speed, press the Speed Down key. The treadmill will automatically return to 0 MPH. Please allow the unit to stop completely before continuing.


9) THIS IS A VERY IMPORTANT STEP BECAUSE YOU WILL GET AN ERROR MESSAGE IF THIS STEP IS SKIPPED. Press the Stop key once and remove the safety key.
