FEATURES OF THE CONSOLE The treadmill console offers a selection of features designed to make your workouts more effective. When you select the manual mode of the console, you can change the speed and incline of the treadmill with the touch of a button.
HOW TO TURN ON THE POWER 3. Start the walking belt. IMPORTANT: If the treadmill has been exposed to cold temperatures, allow it to warm to room temperature before turning on the power. If you do not do this, the console displays or other electrical components may become damaged. Plug in the power cord (see page 12). Next, locate the reset/off circuit breaker on the treadmill frame near the power cord. Switch the circuit breaker to the reset position.
The lower left display— As you exercise, the lower left display can show the elapsed time, the distance that you have walked or run, and the incline level of the treadmill. To measure your heart rate, stand on the foot rails. Hold the contacts for approximately Contacts 10 seconds— avoid moving your hands. When your pulse is detected, your heart rate will be shown. For the most accurate heart rate reading, continue to hold the contacts for about 15 seconds.
HOW TO USE A SPEED WORKOUT the next segment, the speed or incline setting will flash in the display to alert you. 1. Insert the key into the console. The workout will continue in this way until the last segment of the profile flashes in the display and the last segment ends. The walking belt will then slow to a stop.

Reattach the Hood (not shown), and run the treadmill for a few minutes to check for a correct speed reading. 1/8 in.
EXERCISE GUIDELINES Burning Fat—To burn fat effectively, you must exercise at a low intensity level for a sustained period of time. During the first few minutes of exercise, your body uses carbohydrate calories for energy. Only after the first few minutes of exercise does your body begin to use stored fat calories for energy. If your goal is to burn fat, adjust the intensity of your exercise until your heart rate is near the lowest number in your training zone.
