with the other. Continue to hold the Start and Fast key until the window displays Factory settings, then
press the enter key.

down key to show which you want, then press enter.
4) Make sure the wheel size diameter is: 2.32 for ET488 and 2.83 for ET588 then press enter
5) Adjust the minimum speed (if needed) to 0.5 and then press enter
6) Adjust the maximum speed (if needed) to 10.0 for ET488 and12.0 for ET588 and then press enter
7) Adjust the maximum elevation (if needed) to 10 for ET488 and 15 for ET588and then press enter
8) Press start to begin calibration. The process is automatic; the speed will start without warning, so do
not stand on the belt.
Adjusting the speed sensor:
If the calibration does not pass you may need to check the speed sensor alignment.
1) Remove the motor cover hood by loosening the 4 screws that hold it in place (you do not need to
remove them completely).
2) The speed sensor is located on the left side of the frame, right next to the front roller pulley (the pulley
will have a belt around it that also goes to the motor). The speed sensor is small and black with a wire
connected to it.
3) Make sure the sensor is as close as possible to the pulley without touching it. You will see a magnet on
the face of the pulley; make sure the sensor is aligned with the magnet. There is a screw that holds the
sensor in place that needs to be loosened to adjust the sensor. Re-tighten the screw when finished.
Maintenance menu:
1) Press and hold the Start, Stop and Enter key at the same time, until the display shows Engineering
mode (it may say maintenance menu, depending on version). Press the Enter key.
2) You can now scroll through the menu using the up and down keys. Use the Stop key to return to
previous menu selection. The menu selections are:
1) Calibration (used to verify calibration)
