6. The display will momentarily read KEYBOARD.
7. The keyboard test will place two dots on the display for each key on the display, including
the numeric keypad. Pressing a key will cause the upper of the two dots associated with the
key to go out. Test all of the keys in this manner. Tug on the safety key lanyard, to ensure
that the STOP key will activate.
8. Press and hold the ENTER key to proceed to the heart rate test.
9. The display will momentarily read HEART RATE.
10. The heart rate test will display the heart rate being received during this test from either a
chest strap transmitter or test transmitter.
11. Two heart rate values will be displayed. They will be prefixed "U" for unfiltered and "F" for
filtered. The Polar heart rate will be displayed in the small upper window.
12. Press the ENTER key to proceed to the lift test.
13. The display will momentarily read LIFT A/D.
14. Two numbers will be displayed, the percent of lift and A/D number related to the current lift
position. The A/D (analog to digital) number represents the lift potentiometer reading. The
A/D number will be in the range of 0 to 255.
15. The lift may be operated using the INCLINE keys. The lift A/D number will change
accordingly.
16. The A/D reading will be used later in this service manual to calibrate the lift.
17. Press the ENTER key to proceed to the belt speed test.
18. The display will momentarily read BELT M.P.H.
19. The speed of the running belt is controlled by the SPEED keys during this test.
20. The following values are displayed; power bits (PWM value) and belt speed (in M.P.H.).
21. This test is valuable in diagnosing treadmill load conditions such as running bed and/or
running belt condition. As load is increased, the speed is kept at a constant value (as set via
the SPEED keys) and the current and power bits will vary proportionately to the load.
