At the beginning of each four-minute level, the speed and/or the incline of the treadmill will auto- matically increase. The fitness test program will continue in this way until your heart rate reaches 70% of your estimated maximum heart rate, and the current four-minute level is completed. The fit- ness test program will then be completed, regard- less of how many levels remain.

When the fitness test program is completed,

the letter “C” will appear in the main display and a two-minute cool-down period will begun. The

incline will then adjust to 1% and the speed will de- crease.

When the cool-down period is completed, the walking belt will slow to a stop. After the fitness test program is com-

pleted, your fitness level will be shown in the main display. There are ten fitness levels;

fitness level 10 (FL:10) is the highest. Remem-

ber, the fitness program is intended only to indi- cate your relative fitness level.

Note: The Speed and Incline buttons will not function while the fitness test program is selected. If your pulse is not detected during the program, the letters “PLS” will flash in the main display. If your pulse is not detected during the last thirty seconds of any four-minute level (after four minutes, after eight minutes, etc.), the fitness test program will end and the main display will show a fitness level of 0 (FL: 0).

The fitness test program cannot be stopped tem- porarily and then restarted. However, the program can be stopped at any time by pressing the Stop button. The main display will then show an esti- mated fitness level.

6 When the program has ended, remove the key.

See step 6 on page 13.
