Press the Stop and the Speed Up keys down while inserting the safety key. This should get you into calibration mode. Press the Stop key one time. The Time window should read EP:2P. Some newer models may also say FP, Pass, or the like. This means that it passes the EPROM test. If you cannot get into calibration or if the EPROM test fails then the upper console will have to be replaced.
If you get pass to this point then proceed with the calibrating the incline and speed.
Press either incline key and the incline will calibrate automatically.
Be careful the treadmill will run at full speed in the 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 (some models may show the 85 number in another window).
If the top speed of the treadmill does not match the displayed speed on the computer console, adjust the max speed potentiometer (pot) on the motor control board. This is the board that the red and black motor wires connect directly into in the motor area. The Max Speed pot is clearly labeled
The max speed potentiometer is a small square with a mobile center and is located in one corner of the board and is labeled MAX SPD. It is near the harness that carries the speed signal 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.
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 check your manual if you aren’t sure.
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. Press the Stop key once and remove the safety key.

Dear Friend:
Thank you by your request.

I will try to help you inmediately:

nstructions Things You'll Need

• Phillips screwdriver
• Allen wrenches (included with the Proform 980 and Proform 980CS)

1. Power
   • 1 Ensure that the treadmill is plugged into a grounded outlet using the correct surge suppressor. Use a UL 1449 suppressor listed as a transient voltage surge suppressor (TVSS). It must be rated for 15 amps and 120 volts AC. Secure the services of an electrician if the outlet is not grounded, or move the Proform treadmill near a grounded outlet. Do not use an extension cord.
     
   • 2 Insert the safety key fully into the display. Treadmills with keys are designed not to turn on without the safety key in place.
     
   • 3 Find the circuit breaker on the front of the frame and make sure it is not tripped. The circuit breaker is a vertical switch on the 98CS and a horizontal switch on the 980 Interactive Trainer. Press it to the "Reset" position, which will be labeled.
     
   Reed Switch
   • 1 Unplug the treadmill and remove the safety key.
     
   • 2 Move the upright base of the treadmill down with the help of another person and lift the uprights so that you can get to the underside of the console. Use a Phillips screwdriver with at least a 5-inch shaft to remove the screws. There are five hood screws on the 980 Interactive trainer and four screws on the 980CS.
     
   • 3 Remove the motor hood to get to the small reed switch by pivoting the hood off the frame. Find the reed switch and magnet, which are on the left side of the pulley for both models.
     
   • 4 Turn the pulley with your hand until the reed switch aligns with the magnet. There should be 1/8-inch gap between the two. Fix the distance so that it is 1/8 inch by loosening the reed switch screw and sliding it to the correct distance. Tighten the screw.
     
   • 5 Reverse the directions to put the hood back on and the treadmill upright in the original position.
     
   Optic Sensor
   • 1 Unplug the treadmill, take out the key and remove the hood cover.
     
   • 2 Locate the optic disc and optic sensors. The optic disc is the only circular disc set between two optic sensors.
     
   • 3 Spin the disc with your hand. It must spin without hitting either of the sensors. Loosen the adjustment bolts that hold the switches in place with the included Allen wrench and adjust them to ensure they do not interfere with the discs' ability to spin. Tighten the bolts and replace the hood

   Thank you in advance, sincerely. Blessing.

SOURCE: pro-form 980, regardless what button I hit the speed goes to 12

1) test the speed sensor, for open or faulty, see the adjustment. Clean if and tight the connector very well
2) tight the ribbon cable for keypads , and clean it
3) replace batteries,and clean the contacts baterries very well
4) adjust the Reed swtich, test for open or faulty, clean it and tigh the connector very well see the diagram
5) Run the software calibration for troubleshooting, diagnose, and fix it.
God bless you
