Model Differences
INTRODUCTION
MODEL
DIFFERENCES
Your new 550 ZTX treadmill, the finest home treadmill ever
produced, is part of a family of three treadmills with a variety
of combinations of features. Since this owner's guide covers
all three models, you might notice explanations of features
that are different from your treadmill.
Here are the differences between the three models:
Programmed (P) model:
w 10 x 25 pixel tri-color LED matrix display
w all four pre-set workout programs
w no heart rate receiver or heart rate control
INTRODUCTION
Heart Rate Control (HRC) model adds:
w four different heart rate control modes
w Polar heart rate receiver

Top Features
INTRODUCTION
Cardiointeractive (CI) model adds:
w larger 14 x 50 pixel tri-color LED matrix display
w motorized S.O.F.T. Select deck softness adjustment
INTRODUCTION
Your 550 ZTX treadmill has all the expected features of a
premium fitness product, such as four interesting preprogrammed workouts, a wide-ranging Manual workout mode,
and displays of distance and calorie accumulation.
But it also has some unique and useful features that bring you
increased convenience, comfort, and performance:
S.O.F.T. Select: actually change the way the treadmill deck
feels to your footplants. (See Chapter 3.)

More on Top Features
INTRODUCTION
User Programs: record up to
three different workouts simply
by using Manual mode — the
treadmill remembers each one
individually so you can use them
later as your own custom
programmed workout. (See Chapter 6.)
True Touch keys: feather-light
sensitivity eases data entry and
control.
In the HRC and CI models:
Heart Rate Control: the
treadmill controls both speed
and incline to keep your heart
rate in a target zone. Nine
different workout setups, mixed
between time- or distance-based
workouts, can be saved to use later. (See Chapter 7.)
INTRODUCTION
Interval Heart Rate Control: a target heart rate work interval
is mixed with a reduced workload
rest interval, and you pick how
long each of these is. Five different
target and interval setups can be
saved.
Cruise Control: set your current heart rate as your target
heart rate by pressing a single key.

Set your weight using the and keys or the numeric keys
and press .

SETTING YOUR

Care should be taken when using the numeric keys to control
your treadmill's speed and incline, since large changes in
those values are 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.
550ZTX Treadmill Owner’s Guide
19
Calorie Expenditure Calculations
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.)
BASIC OPERATION
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.
A NOTE ABOUT
CALORIE
EXPENDITURE
CALCULATIONS

Variations in human exercise efficiency are another potential
source of error, with differences of plus or minus 10%
common in the population.

TRAP
The 550 ZTX treadmill (models HRC and CI) can monitor your
heart rate when you wear the transmitter strap provided. It
will display it as a digital beats-per-minute readout, and it is
ATE
very accurate, typically
within one beat per
minute.
Although your 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.
B
ASIC
O
PERATION
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
BASIC OPERATION
Before you start your workout, as you stand on or near the
treadmill, you will know the treadmill is properly receiving
your heart rate signal by the flashing LEDs in the Heart Rate
window, or, on the CI model, a beating heart in the LED
matrix.
Once you start your workout, your heart rate will be displayed

ELECT
SYSTEM
One part of True's unique
cushioning and stability
system is the S.O.F.T.
System. It cushions the
initial impact of your foot
plant near the front of the
treadmill deck, then
transitions to a firm,
secure surface for push-off. The combination of softness, then
firmness — right when you need them — reduces stress on
ankles, knees, hips, and back.
The other part of True's comfort and performance system is
the S.O.F.T. Select adjustable softness surface. You can adjust
the deck support through a 22-inch range by moving the lever
on the right side of the treadmill or, on the CI model, by
pressing the Softer or Firmer keys on the console. The 1
setting is softest and the 12 setting is firmest.
S.O.F.T. Select is especially useful to accommodate users of
differing weights or those with special physical needs.
BASIC OPERATION
The CI Model's Electronic S.O.F.T. Select:
Press and hold the
or keys to
change the target setting in
the message center. To
review your S.O.F.T. Select
setting, quickly press either
