Start the walking belt.

After you have moved the speed control to the
RESET position, slowly slide it upward until the
walking belt begins to move at slow speed.
Carefully step onto the walking belt and begin ex-
ercising. Change the speed of the walking belt as
desired by sliding the speed control. 

To stop the walking belt, step onto the foot rails
and slide the speed control to the RESET position.

Adjust the incline of the treadmill as desired.

To change the incline of
the treadmill, press the
top or bottom of the in-
cline control until the
desired incline level is
reached.

Follow your progress with the  four displays.

SPEED display

ÑThis

display shows the speed
of the walking belt, in
miles per hour. 

TIME display

ÑThis

display shows the
elapsed time.

DISTANCE display

Ñ

This display shows the
distance that you have
walked or run, in miles. 

CALS/FAT CALS
PULSE display

ÑThis

display shows the ap-
proximate numbers of

calories

and 

fat calories

you have burned. (See
FAT BURNING on page
14.) Every seven seconds, the display will change
from one number to the other. Arrows in the dis-
play will indicate which number is currently shown.
Note: This display also shows your pulse when the
pulse sensor is used. 

To reset the displays at
any time, press the
ON/RESET button.  

Measure your pulse, if desired.

To measure your pulse,
stand on the foot rails
and place 

both thumbs

on the pulse sensors as
shown. The pulse sen-
sors are pressure acti-
vatedÑfully press them
down. 

Do not press

too hard, or the circu-
lation in your thumbs
will be restricted, and
your pulse will not be
detected.

Next, raise

your thumbs slightly
until the heart-shaped
indicator in the pulse
display flashes

steadily

. Hold your

thumbs at this level.
After a few seconds,
three dashes will appear in the display and your
pulse will be shown. Hold your thumbs on the sen-
sor for another 15 seconds for the most accurate
reading. 

If the displayed pulse appears to be too high or too
low, or if your pulse is not displayed, lift your
thumbs off the sensors and allow the display to
reset. Press down again on the sensors as de-
scribed above.

Make sure that your thumbs are positioned as
shown, and that you are applying the proper
amount of pressure. Try the pulse sensor several
times until you become familiar with it. Remember
to stand still while measuring your pulse.

When you are finished exercising, stop the
walking belt and remove the key.

Step onto the foot rails, stop the walking belt and
remove the key from the console. The displays will
turn off about five minutes after the key is removed.

Note: To conserve the batteries, the displays
will automatically turn off any time that the
walking belt is stopped and the ON/RESET 
button is not pressed for five minutes.
