Getting Started
Note: Throughout this manual, all references to the left or right side and to the front
or back, are made as if you were on the machine, ready to exercise.
Guidelines for Getting On and Off the SC916 StairClimber
Instruct each user in the following guidelines for getting on and off the
StairClimber.
To avoid injury, please carefully follow the instructions.
1. You should see the “SELECT WORKOUT” message on the display.
2. Select the MANUAL exercise program so you can control the pace of your first
workout and get used to the exercise motion. Press [MANUAL] and then press
[ENTER].
3. The console will prompt you to enter your body weight. Enter your weight in
pounds (or kilograms if the console is set to metric units). Correct entry errors
by pressing [CLEAR] before you press [ENTER].
4. The console will prompt you to enter your step rate. Enter your desired step
rate from 24 (very easy) to 162 (extremely hard). First time users may want
to select a low step rate, for example, 24. Correct entry errors by pressing
[CLEAR] before you press [ENTER].
5. The console will prompt you to enter the workout time in one-minute
increments between 5 and 99 minutes. Press [1], [0], [ENTER] to exercise
for ten minutes. After time is entered, the console will display “ENJOY
WORKOUT” and your program will begin. If you do not start exercising within
30 seconds, the console will return to the start screen and shut down.
6. Begin pedaling so the pedals do not hit the ground during the workout. When
you begin to exercise, the MANUAL program starts at the level you selected
during data entry.
7. As you become comfortable with the exercise motion, press [LEVEL:£] and
[LEVEL:] to adjust the step rate.
8. Relax while exercising.
9. Before stepping off the StairClimber, stop and let the pedals slowly bring you
to the floor. Use the Side rails for support and lift one foot slowly until the
pedal arm contacts the upper stop. Place that foot on the floor. Repeat for
the other foot. Do not let the pedals slam into the upper stops, since this may
cause unnecessary wear and tear.

Operation
STEP RATE Pressing the £ key increases the workload intensity and
pressing the  key decreases the workload intensity.
User should consult a physician to determine an appropriate Target Heart
Rate (THR) in which to exercise, based on age, weight and physical
condition. While Nautilus® provides some THR ranges, these are only
approximations and should not be viewed as a medical recommendation.
HEART RATE
Current Heart Rate (HR), in Beats Per Minute (BPM), is
displayed next to the heart icon on the lower display.
Percentage of Maximum HR - An approximation of maximal HR is calculated
based on the latest American College of Sports Medicine predictive equation as
follows:
Max Heart Rate = 215 – (Age * .75)
Percentage of maximum HR will only be shown in HRC programs.
Example: For a person 40 years of age, max HR is estimated as (215 – (40 (age) *
.75) = 185 . 185 BPM would be the approximate maximum HR for a
40-year-old user. If the user works out at 140 BPM, then 76% (140 / 185
= 76%) will be displayed in the upper left corner of the lower display
area. This means that the 40-year-old user working at 140 BPM is at
76% of their maximum HR.
(See the Heart Training programs for more information.)
DISTANCE
Provides a cumulative total of the equivalent distance, in
miles (or kilometers if your display is set to metric units),
you have traveled.
CALORIES
Provides a current total of the number of calories burned
during a workout.
Note: This number is only an approximation as a user’s
caloric expenditure will vary significantly based on a
person’s age, gender, weight and metabolism.
CALORIES/HOUR Provides the rate at which calories are burned per hour at
the current resistance level and steps per minute.
SPEED Displays the step rate in steps per minute (SPM).

Operation
WATTS
During a workout, this statistic displays the power output at
the current RPM and intensity level, displayed in watts (746
watts = 1 hp).
METs MET (multiple of the resting metabolic rate) indicates the
relative energy cost of exercise. While you are sitting
quietly, your body consumes oxygen at the rate of 1 MET
or about 3.5 milliliters per kilogram of body mass per
minute. When you exercise, your body needs more oxygen
in order to function. For example, exercising at 10 METs
requires ten times the resting rate of oxygen consumption,
or about 35 milliliters per kilogram per minute. During a
workout, the display shows the current MET level. During
the workout summary, the average MET level is displayed.
During your workout, keeping track of the METs will show
you how hard you are working—the higher the MET level,
the harder you are working.
WORKOUT PROFILE The dot-matrix area of the display shows the actual course
profile of the selected exercise program. The taller the
column, the higher the step rate and/or METs for that
interval. The flashing column shows your current interval.
KEY FUNCTIONS
Display LOCK / UNLOCK - Statistics Key
During the exercise program, the Display LOCK / UNLOCK key is used to track
workout statistics which are shown in the text line of the display window. When
a workout is started, the display is in an unlocked mode and the various exercise

The Nautilus® Fit Test Program
Understanding Sub-maximal Exercise Testing
Before using the StairMaster ® SC916 StairClimber for sub-maximal exercise
testing, it should be noted that all sub-maximal tests make several assumptions:
•
That a steady-state HR is obtained for each exercise workload.
•
T hat a linear relationship exists between HR, oxygen uptake and workload.
•
That the maximal HR for a given age is uniform.
•
T hat the mechanical efficiency of the physical activity performed (i.e. oxygen
uptake at a given workload) is the same for everyone.
It should be kept in mind that any one or all of the above mentioned assumptions
may not be met during a sub-maximal exercise test. If for any reason one of the
assumptions is not met, then errors in predicting VO 2 MAX (Maximum volume of
oxygen consumed per unit of time)will occur.
Unfortunately, it is often quite difficult to meet all of the requirements for the four
listed assumptions. For example, exercising at a given workload for only a few
minutes can involve an insufficient amount of time for many individuals to achieve
a true steady-state. To ensure that a steady-state has been achieved, the HR
21
Owner’s Manual
STM_SC916 _OM_RevA_021208_Print.indd 21
2/12/2008 7:57:06 AM
Operation
should be measured after two minutes of exercise at a given workload and again
after the third minute of exercise at that workload. These two HR’s should then
be compared. If a difference of more than five beats per minute between the
two is found, the subject should continue to exercise at one-minute intervals at
the same workload until two successive HR’s differ by less than five beats per
minute.
It is also important that the sub-maximal HR obtained be between 115 and 150
BPM, because it is within this HR range that a linear relationship tends to exist
between HR and oxygen uptake or workload for most adults. When the HR is less
than 115, many external factors (e.g. talking, laughing, apprehension, etc.) can
greatly influence HR. Once the HR reaches a level between 115 and 150, external
factors no longer influence HR, and a linear relationship exists. As the HR rises
above 150, the HR/oxygen uptake relationship becomes curvilinear.
The third assumption involves maximal HR. Maximal HR is the greatest HR that
can be measured when an individual is exercising to the point of volitional fatigue
(i.e. exhaustion) during a graded exercise test. The SC916 StairClimber uses the
most current published equation developed to estimate the average maximal HR
as follows:
Max Heart Rate = 215 – (Age * .75)
Maximal HR can, however, vary greatly among different individuals of the same
age. One standard deviation is ±12 BPM, which means that two-thirds of the
population varies an average of plus or minus 12 heart beats from the average
given by a prediction equation. If an individual’s age-predicted maximal HR is
higher than that person’s true maximal HR, then his/her estimated VO 2 MAX will be
an overestimation of the correct or actual value.
The final assumption addresses the issue of mechanical efficiency. Oxygen
uptake at any given work rate can vary by approximately 15% between different
individuals. Therefore, individuals vary in the amount of oxygen they require
to perform a certain exercise workload. Some individuals are more efficient
at performing a given task than others. As a result, the average oxygen
consumption associated with a given workload may vary significantly from one
person to another. Thus, VO 2 MAX predicted by sub-maximal exercise tests tends
to be overestimated for those who are mechanically efficient and underestimated
for those who are inefficient.
The point to remember is that sub-maximal exercise testing, though not as precise
22
Owner’s Manual
STM_SC916 _OM_RevA_021208_Print.indd 22
2/12/2008 7:57:06 AM
Operation
as maximal exercise testing, is not without advantages. For example, the results
of such testing can provide a fairly accurate reflection of an individual’s fitness
status without the cost, risk, effort (on the part of the subject) and time involved
in max testing. If an individual is given repeated sub-maximal exercise tests and
that person’s HR response to a fixed workload is found to decrease over time, it is
reasonably safe to conclude that the individual has made improvements in aerobic
(cardiorespiratory) fitness, irrespective of the accuracy of the VO 2 MAX prediction.
Pretest Screening
Prior to any exercise test (maximal or sub-maximal), participants should
complete a brief health/medical questionnaire, have their resting blood pressure
and HR measured, and provide an informed consent form. The Physical
Activity Readiness Questionnaire (PAR-Q) is an example of a valid health/
medical questionnaire for screening individuals prior to sub-maximal exercise
testing. Canadian health and fitness practitioners have extensively (and quite
successfully) used the PAR-Q to determine whether individuals should be given
an exercise test. A “yes” answer to any of the following seven questions taken
from the PAR-Q would disqualify a participant from taking part in an exercise test
until appropriate medical clearance was obtained.
Physical Activity Readiness Questionnaire (PAR-Q)
1.Has your doctor ever said you have a heart condition and recommended only
medically supervised physical activity?
2. Do you have chest pain brought on by physical activity?
3. Have you developed chest pain within the past month?
4. Do you tend to lose consciousness or fall over as a result of dizziness?
5. Do you have a bone or joint problem that could be aggravated by the
proposed physical activity?
6. Has a doctor ever recommended medication for your blood pressure or a
heart condition?
7. Are you aware, through your own experience or a doctor’s advice, of any
other physical reason against your exercising without medical supervision?

Nautilus® Sub-maximal Fit Test
The Nautilus ® Fit Test is a program that estimates maximal aerobic capacity
based on HR response to sub-maximal exercise.
The Nautilus ® branching protocol is a series of 3-minute stages of continuous
exercise at increasing intensity. The first stage is a warm-up at approximately
4 METs. The intensity of the remaining stages is based on the HR response to
the warm-up. The test is designed to raise the steady state HR of the subject
to at least 115 BPM. It is important to remember that two consecutive HR
measurements must be obtained above 115 BPM to predict VO 2 MAX . The test
typically lasts from 6 to 15 minutes. The test will terminate if the HR does not
continue to rise from state to stage.
In the Nautilus ® protocol, each work rate is performed for 3 minutes, with HR’s
recorded during the final 4 seconds of the second and third minutes of each
stage. If the HR’s are within 5 BPM, then the HR during the last minute is plotted
against the work rate, and the program advances to the next 3-minute stage. The
program continues for two to four stages until two steady state HR’s above 115
BPM are obtained in two consecutive stages. The line generated from the plotted
points is then extended to the age-predicted maximal HR. A corresponding
maximal work rate and VO 2 MAX can then be calculated.
At the end of the 3rd minute of each stage, if the HR’s at the end of the 2nd and
3rd minute are not within 5 BPM of each other, then that work rate is maintained
for an additional minute. At the end of the 4th minute, the HR is compared to the
HR at the end of the 3rd minute. If the HR’s are within 5 BPM, then the HR during
the 4th minute is plotted against the work rate. If the HR at the end of the 3rd and
4th minute are not within 5 BPM, then the work rate is maintained for one more
additional minute. If the HR at the end of the 4th and 5th minutes are within 5
BPM, then the HR at the end of the 5th minute is plotted against the work rate. If
the HR at the end of the 4th and 5th minutes are not within 5 BPM, then the test
failed.
Once two consecutive HR measurements are obtained above 115 BPM range,
then the test ends successfully and the results are displayed. Estimated
maximum aerobic capacity is shown in ml/kg/min and METs. Next, the results
are compared to normative values for others of the same age range and gender.

HEART RATE MONITORING
HR monitoring helps users monitor their levels of exertion by displaying the HR
during exercise. There are two methods of monitoring HR on the Commercial
Series SC916 StairClimber:
•
T elemetry (e.g. using a Polar® or Polar-compatible transmitter belt). A Polarcompatible HR chest belt transmits the heart beat signal to the receiver in the
display. The display shows the HR in beats per minute and uses the HR value
in HR control mode.
•
ontact HR (handgrip). Sensors on the handgrip detect HR and display it on
C
the controller.
Pacemaker users should not use the telemetry transmitter without
first consulting with their doctor.
Telemetry Heart Rate
The telemetry HR monitoring system consists of the
receiver, located in the display, and a transmitter belt
(purchased separately) worn across your chest. The
monitoring function is activated as soon as you strap
on the chest belt and step within range of the receiver
in the machine. Two electrodes on the underside of
the chest belt sense the HR signal and send it to the receiver. The far right decimal
point in the HR Display pulses to indicate that the display is receiving a valid signal.
A microprocessor in the controller calculates the HR and shows it, in BPM, on the
display.
Before you put the transmitter belt on, wet the two electrode patches (the grooved
rectangles on the reverse side of the belt). Secure the transmitter belt as high
under the pectoral muscles (chest) as is comfortable. The transmitter belt should
fit snugly and comfortably, and allow normal breathing.
After the initial belt signal is detected, the display will enter a validation phase in
which four good heart beat signals lasting four seconds are required before locking
on telemetry HR signals for the duration of the workout session.
If your HR is not being displayed, try the following:
•
•
•
Move closer to the display.
Tighten the elastic band on the chest belt.
Adjust the belt higher or lower on your chest.

•
•
Remoisten the electrodes.
Test your chest strap with a machine that you know is working, or with a HR
watch that you know is working.
Maintaining the Transmitter Belt
Clean the chest belt regularly with mild soap and water, then dry thoroughly.
Residual sweat and moisture keeps the transmitter active and will drain the battery
in the transmitter. Do not use abrasives or chemicals such as steel wool or alcohol
for cleaning, as they can damage the electrodes permanently. Replacement belts
can be purchased from an Authorized Nautilus Fitness Retailer or at
www.nautilus.com.
Contact HR
Through the use of stainless steel sensors built into the handle bar and using
sophisticated software, HR can be checked at any time during a workout. As
with the wireless telemetry chest belt, the HR is shown on the display in the same
manner.
The contact HR system’s ability to detect a HR signal is influenced by several
factors. Movement of the muscles of the upper body produces an electrical
signal (muscle artifact) that will interfere with the detection of the HR signal by
the sensors. Movement of the hands while they are in contact with the sensors
also produces interference. Calluses and hand lotion act as an insulating layer to
reduce the signal strength. Also, the EKG signal generated by some individuals is
not strong enough to be detected by the sensors. These individuals should opt for
the telemetry method of HR monitoring. Contact HR input signals are acquired only during contact between your hands
and the stainless steel sensors on the handrails. To use the contact HR feature,
place your hands around the handles so that your hands touch both the top and the
bottom of the sensors. After the initial contact HR signal is detected, the controller
will enter a validation phase requiring a good heart beat signal within 10 to 15
seconds, or until the system acquires a valid signal. During the validation phase
the controller will not recognize telemetry HR signals. The controller will display a
heart icon.
If, during exercise, the HR displayed is erratic, it may be helpful to remove your
hands from the handles, wipe them and place them back on the handles. In all
programs, the HR is shown automatically in the display window the first time the
sensors are touched.

HEART RATE PRIORITY
Both contact HR and telemetry (e.g., Polar®) HR signal detection are available. The
default priority of HR input is “EITHER INPUT.”
Locked/Non-Locked HR Signal Options
The “EITHER INPUT” option means that the HR source signal is not fixed during
the workout session (if the signal is lost either input will be valid). If the “LOCKED
INPUTS” option is selected then the HR source signal is locked on the first
detected signal during the workout. To set a HR signal input, or to turn off the HR
option all together, perform the following steps:
1.On the console keypad, press [Level: UP], [3], [ENTER]. At this point the
screen will display “Customize”. Use the [Level: UP] key until “HR INPUTS”
appears, then press [ENTER] to select th option.
2.There are six options to handle HR input signals. Press the [Level: UP] and
[Level: DOWN] keys to scroll through the options until you find the option that
you want. Press the [ENTER] key to select that option.
The options are as follows:
LOCKED INPUTS
EITHER INPUT
Allows either telemetry or contact HR signals to be
detected. Once the console has detected a valid input
signal it will lock out the opposite type of signal for the
duration of the workout session. For example, if you start
out using contact HR then you are limited to using only
contact HR during your workout session, even if the signal
is lost while performing the workout, and vice-versa.
Allows either telemetry or contact HR signals to be
detected. Does not lock out a particular input signal for the
entire workout. This option will detect either input signal
during a workout session, but only one at a time, and only
until the other signal terminates.
TELEMETRY ONLY
Locks out contact HR signals and will only detect telemetry
signals.
HAND ONLY
Locks out telemetry signals and will only detect contact HR
signals.

BOTH HR OFF
Turns off the ability to detect any HR signal. Used in rare
situations where there is excessive interference with the
HR signals. During workouts where HR is necessary, such
as the HR Zone Trainer and the Fitness Test, the console
will pick up telemetry HR signals so that the programs are
not disabled.
HAND HR PGRM OFF Means that the HR control programs require a telemetry
strap to work.

Maintenance
Checking the Battery Charge
1. Using your multimeter, touch the red lead to the positive terminal
a diluted, non-min of the battery and the black lead to the negative terminal.
2. If the voltage level is less than 6.1 VDC, charge the battery.
Charging the Battery Back-Up
The StairMaster® Commercial Series SC916 StairClimber is selfpowered (cordless)
with a rechargeable battery back-up. Typically, the StairClimber can be operated
without plugging in the external power supply. If, however, the console flickers
during operation or the console display does not light up while using the machine,
then use the external power supply to recharge the battery back-up.
The external power supply is supplied with the unit and plugs into a standard
115 volt, 15 amp outlet, or a 220 volt, 10 amp outlet. (All major voltage plugs are
available.) The plug-in for the external power supply is located in the front of the
machine at the base.
IMPORTANT: If installing the optional LCD Monitor, refer to the NV915 installation
manual at this time.
Plug the wall pack external power supply into the connector and charge the battery
for approximately 24 hours and then recheck it. It is okay to use the machine while
the external power supply is connected.
The console will power on as user starts to move the pedals of the machine, and
will stay lit for up to 60 seconds in pause mode. The console will power off after
60 seconds of stopping exercise. The console will power on and remain powered
whenever the external power supply is connected.
Battery Disposal
When ordering new batteries, you will need to properly dispose of (recycle) your old
lead-acid batteries. Most federal and state regulations require lead-acid batteries
