Your new treadmill is part of the True Z8 and Z9 Series treadmills,
which are all built to the same heavy-duty standards. Since this
owner’s guide covers all five Z8 and Z9 Series models, you might
notice explanations of features that are different from your treadmill.
The main differences are in the consoles. The following section
describes the model differences:

incline with the numeric keys,
then press the small Enter key

that incline.
Care should be taken when using the numeric keys to control your

possible with just a few keystrokes.
Slow the treadmill to below 2 mph using the
key. Press .
Your body weight must be entered so that the treadmill accurately
estimates your calorie expenditure. This weight must include your
workout clothing, too, which typically adds about three pounds.
The treadmill will work fine without your weight setting, but will be
unable to calculate your total calories.
The treadmill will remember the last weight you entered.

BasIc operatIon
Calorie Expenditure Calculations
three : BasIC operatIon
True treadmills use the calorie expenditure formula as described in
Guidelines for Exercise Testing and Prescription from the American
College of Sports Medicine. This is the most widely
accepted formula for running and walking.
The ACSM guide says that running burns calories
twice as fast as walking, e.g., a 150-pound person
jogging at 5 mph requires 548 calories per hour, while
walking at 5 mph requires 274 per hour. See Appendix
C for more details.
(Other respected researchers such as David Costill think the ACSM
overstates the energy difference between running and walking.
Costill believes running requires 60% more energy than walking, not
100% as calculated by the ACSM. Using the same example, Costill's
calculations result in 496 cal/hour for running 5 mph, with 313 cal/
hour for walking 5 mph.)
One potential source of calorie estimate
error is that the treadmill doesn't know
if you are running or walking, so it has
to make some assumptions. It assumes
you are walking at 3 mph and slower,
and running at 5 mph and faster. Between those two speeds, the
treadmill combines the walking and running formulas to make its
best guess.
Variations in human exercise efficiency are another potential source
of error, with differences of plus or minus 10% common in the
population

Heart Rate Monitoring
three : BasIC operatIon
The Z8 and Z9 Series (except the Z8 and Z9
Non) can monitor your heart rate when
you wear the transmitter strap provided.
It will display it as a digital beatsper-minute readout, and it is
very accurate, typically within one
beat per minute.
Although the treadmill functions fine without using the heart rate
monitoring feature, this kind of monitoring gives you valuable
feedback on your effort level. It also allows you to use the most
advanced training system available on a treadmill: True's Heart Rate
Control, where the treadmill automatically adjusts your workout
level based on your heart rate. See the Heart Rate Control section of
this manual for details.
The transmitter strap should be worn directly
against your skin, about one inch below the pectoral
muscles/breast line.
Women should be careful to place the transmitter
below their bra line.
Some moisture is necessary between the strap and
your skin. Sweat from your exercise works best,
but ordinary tap water may be used prior to your
workout if desired.

The Heart Rate Display
three : BasIC operatIon
Once you start your workout, your heart rate will be displayed in
beats per minute.
The contact heart rate system lets you monitor your heart rate
without wearing a strap.
