Auto-Calibration Procedures
The T40, T30, and T20 models have a built-in auto-calibration sequence into the software
programming. This will allow the rpm sensor reading to be detected and stored in the
upper board. This process is performed at the factory and will not need to be repeated
unless replacing the upper board or lower board in your Horizon Series treadmill. To
perform the auto-calibration sequence, follow the instructions below:
Step 1. Adjusting the Speed Cube
With the treadmill power on and the safety key in position on the console, press and hold
the Incline “+” and Speed “-“ keys for about 5 seconds to enter the Engineering Mode
Menu. The console should beep three times and Eng 0 should be displayed once in the
Engineering Mode Menu.
Press Speed “+” or “-“ until Eng1 appears in the display.
Press and hold “Start” for three seconds to select.
Press “Start” to begin. At this time, the running belt should begin moving.
The readout in the speed window will indicate the start speed of the treadmill, which
should be 0.5 mph (+ or - .05 mph). If the speed is not within the proper start speed
range, adjust the Speed Cube located on the board under the motor cover until the speed
is approximately 0.5 mph (+ or – .05 mph) in the Speed window.

Once the speed cube is set to the proper setting, press and hold the “Stop” button for three
seconds to return to the Engineering Mode Menu.
