NordicTrack 4200r Treadmill User Manual - Page 18

During the program, the console will regularly compare your heart rate to the current target heart rate setting. If your heart rate is too far below or above the target heart rate setting, the speed of the treadmill will automatically increase or decrease to bring your heart rate closer to the target heart rate setting. If the speed reaches the maximum speed limit for the program (see step 5 on page 17) and your heart rate is still too far below the current target heart rate setting, the incline of the treadmill will also increase to bring your heart rate closer to the target heart rate setting. The program will continue until no time remains in the program. The walking belt will then slow to a stop. If the current speed or incline setting is too high or too low, you can adjust the setting with the Speed or Incline buttons. However, each time the console compares your heart rate to the current target heart rate setting, the speed and/or incline of the treadmill may automatically change to bring your heart rate closer to the target heart rate setting. If your pulse is not detected during the program, the letters "PLS" will flash in the Incline/Heart Rate display and the speed and incline of the treadmill may automatically decrease until your pulse is detected. If this occurs, refer to the instructions on page 8. To stop the program at any time, press the Stop button. Heart rate programs should not be stopped temporarily and then restarted. To use a heart rate program again, reselect the program and start it at the beginning. 7 Follow your progress with the displays. See step 5 on page 12. 8 When the program is completed, remove the key from the console. See step 6 on page 14. 18
