1) adjust the Reed Switch , see the diagram clean it, tight the wires connector very well.

It is simple to change your treadmill so it reads MPH.

Treadmills are an easy and relatively inexpensive way of maintaining physical fitness. Most modern treadmills have a readout on their console that will track your speed over time in kilometers per hour or miles per hour. If your treadmill came with the wrong setting, it is possible to toggle between these two settings.

[from my Owner's Manual]...
On MY Free Sprit mdl 309180:
1. Remove the safety tether from the treadmill.
2. Press POWER button and hold.
3. While pressing the POWER button, insert the safety tether.
4. After lights on the LED display go out, release POWER button. You will hear a beep.
5. Press POWER button again. You are now in kilometers per hour.
* Repeat steps 1 - 5 to convert to miles per hour.
* If you are in kilometers per hour mode, you will see a "Si" in the time section when the safety tether is inserted.
* If you are in the miles per hour mode, you will see a "bri" in the time section when the safety tether is inserted.

Hope this helps,

It's in Miles The treadmill goes a max of 14km an hour - if you increase the speed it only goes to 8 - 14km per hour is 8.4 miles per hour and I've been running between 5.5 and 6.5 and covering 3 miles which would be about right :) Hope this helps
