appear in the main display.

Incline buttons. Each
time a button is
pressed, the incline will
change by 0.5%. The
incline range is 0% to 12%. To change the incline
quickly, press the 1-step incline buttons. Note:
After the buttons are pressed, it may take a moment
for the treadmill to reach the selected incline setting.

Follow your progress with the LED track, the
Training Zone display, and the main display.

the manual mode or an
iFIT.com program is se-
lected, the program dis-
play will show an LED
track representing 1/4
mile. As you exercise, the indicators around the
track will light in sequence until you have completed
1/4 mile. A new lap will then begin. 

The Training Zone dis-
play
—As you exercise,
the Training Zone 
display will show the 
approximate intensity
level of your exercise.
For example, if four to six indicators in the display
are lit, your intensity level is ideal for fat burning.

The main display—The main display will show
the following information:

Incline—The left side of
the main display shows
the incline level of the
treadmill. 

Time—When the man-
ual mode or an iFIT.com
program is selected, the
main display will show
the elapsed time. When
a different program is se-
lected, the display will show the time remaining in
the program and the time remaining in the current
segment of the program. The display will change
from one number to the other every seven sec-
onds. Note: During the fitness test program, the
display will show the elapsed time and the time re-
maining in the current segment of the program.  

Distance/Laps—The
center of the main dis-
play shows the distance
that you have walked
and the number of 1/4-
mile laps you have com-
pleted. The display will change from one number
to the other every seven seconds.
