Nautilus Trimline T523 Owner's Manual page 13

Programs 3, 4, and 6 are divided into 9 segments. Divide the program time by 9 to compute the length of each segment.
For example, if you choose a program time of 18 minutes, each segment will be 2 minutes long. The display gives a
visual and an audible warning before each segment change if there is a change of speed or elevation. The segments of
each program have a variety of speeds and inclines (See charts). To review your workout results, press START/STOP.
The program repeats until you choose to end the workout by following the "TO STOP" section.
You may override the speed or incline of any segment by using the ARROW (+ or -) keys. The change lasts for your cur-
rent workout. The next time you run the program, it returns to the original settings. If you make a change in speed or
incline during your present workout, the same change is made to every other segment in the program. For example, if
you are in Segment 3 and override the speed by increasing it 2mph (or kph) the speed in all other segments is increased
2mph (or kph).
