Interval (INTV) Program

The Interval Program is among the best for conditioning your cardiovascular system. The program raises and lowers your level of exertion repeatedly for a specified period of time.

When you begin the program, the speed and incline are preset.

You can change the speed and incline levels using the arrow keys. Refer to Diagram 8. The settings are repeated throughout the program.

To change a setting, press the appropriate arrow key and continue. The change is applied to the remaining intervals. Two audible beeps let you know when the speed is about to change.

When you complete the program, any changes made to the incline and speed settings are not saved.

Random (RAND) Program

Every time the Random Program is selected, a different program

profile appears. The columns

that appear in the program profile maintain a set incline that you can override using the INCLINE arrow keys. The incline is preset to zero for the first

column. The maximum incline change allowed between columns is plus or minus 4%.

The running belt speed is completely under your control and can be adjusted using the SPEED arrow keys.
