TMX425 treadmill includes an RS-232 plug that enables you to
test the operation of the treadmill without the ECG unit attached. The plug is contained in
the owner’s information packet. The plug is to be used
only for testing the treadmill. Do
not stand on or use the treadmill while testing.
Note: This procedure will not work with TMX425C or TMX425CP.

Turn the power "OFF" at the treadmill.
Disconnect RS232 interface cable from the treadmill and plug in the test
connector.
Hold the button down on the test connector and turn treadmill power
"ON". Continue holding until treadmill begins to elevate.
Once this is initiated, with each push of the button the treadmill should
elevate 5% grade.
When the treadmill reaches 20% elevation the next push of the button
will start the treadmill running belt.
With each push of the button the treadmill will increase speed by 2.5 miles
per hour.
Once the treadmill reaches 10 mph, each push of the button will bring the
speed down 2.5 miles per hour and simultaneously lower the elevation
level by 5% increments.
When minimum speed and elevation is reached the next press of the
button will cause the treadmill running belt to stop.
Remove the test connector.
Reconnect the RS232 interface cable.
Successful completion of the preceding testing procedure ensures that the treadmill is fully
functional and responsive to command signals through the RS232 port.
