FUNCTION NOTE:
The 10-Series has a safety feature to help prevent users from accidentally increasing the machine speed to a level that is too high
for them. When pressing the level up button to increase speed, there are two stop points at level 10 and level 15 which function
as follows: when increasing level, the machine will not allow the user to increase the level past the stop point until the actual
machine speed has reached the set level. For example, if a user is at level 5 and repeatedly pressed the level up button, it will allow
the set level to go up to level 10, but no further until the actual machine speed has reached level 10. Once the machine speed has
reached the set level, the user can increase the level further.
CONSOLE KEY FUNCTIONS
Bluetooth Device Pairing with Bluetooth Button: Pushing the button puts the console into discover mode. The console
will be available for pairing for up to 60 seconds to pair with a compatible App. The button will ash while searching for

Fan Button: Cycles the fan between three settings: High, Low and O
Pairing with Apple Watch: OpenHub consoles marked with this icon have the capability to connect using
Near Field Communication (NFC) with Apple Watch (must be running WatchOS 4.2 or later). To connect, hold
the Apple Watch near the icon on the console (this is where the NFC reader is located). When the display and Apple Watch detect
each other, the Bluetooth button on the display will ash and then turn solid blue, and Apple Watch will ask user to conrm
connection with the display. Once connection is conrmed by user, it will nalize and data will begin to pass between console
and Apple Watch. It is possible to make this connection either before the workout begins (recommended), or at any time during
an active workout. At the end of workout, the connection will be terminated. Note: when Apple Watch is connected to display,
the Calories display window will display Total Calories, and the scrolling data window will display Active Calories periodically.

Time Goal: Allows entry of a set workout time goal
OverDrive Training Mode: a set of programs that simulate pushing and carrying a load up the stairs.
There are 4 dierent 20 minute program options: Manual (rest and push/carry when you want),
Endurance, Stamina, Power (three dierent HIIT style interval workouts)
Distance Goal: Allows entry of a set number oors to climb during workout (1 Floor = 16 Steps)
GOAL BASED PROGRAMS
NOTE: When a goal based program is selected, user will then have the option to select from a list of program proles, see PROGRAM
PROFILES section for details on the prole options
WORKOUT SELECTION KEYS AND PROGRAM DEFINITIONS
CONSOLE KEY FUNCTIONS
Manual: Similar to Quick Start, but allows user to enter weight for more accurate Calorie measurement
Landmark Challenge: Choose from 1 of 14 dierent famous buildings to climb
Training Tools: Access to HR Zone Trainer
CPAT: Candidate Physical Aptitude Test, used to test reghters in the United States. Consists of a 20 second warm up phase at 50
steps/minute, followed by a 3 minute test phase at 60 steps/minute.
HR ZONE TRAINER: Program requires telemetry HR belt. User will be asked to select a Target Heart Rate (THR). Once the workout
begins, the machine will slowly increase eort level to bring user into the range of THR, and will adjust resistance automatically to
keep user HR in that range. To choose a dierent THR at any time during the workout, use the numeric keypad to enter the new
THR (between 50-190 beats/minute)

Page 10
Once the test is completed, the user should cool down
for a minimum of 2 minutes at 39 steps/min.
The test is aborted with no results if any of the follow-
ing occurs:
•The user stops or pauses the workout at any point during
the test.
•The [STOP] key is pressed.
•The THR has not been met after 16 minutes previous
work level.
•The Heart Rate signal is lost.
•The equipment malfunctions.
Target HR = [208 - (0.7* Age)] * 0.85
BMI
(in - Ibs) = 703* Weight (Ibs) / Height (inches)2
BMI (cm - kg) = Weight (Kg) / Height (cm/100)2 VO2max
= 57.774 + (1.757 x time) - (0.904 x BMI)
The WFI test assesses aerobic capacity expressed as
VO2max. The results are calculated and recorded in
milliliters (ml) of oxygen per kilogram (kg) of body
weight per minute (V02 max).
These aerobic assessments are submaximal and are
based on the heart rate response during graded
exercise. Accurate estimation of maximal heart rate
(MHR) is critical to the submaximal prediction used
in these assessments. A new formula for calculating
maximal heart rate is utilized with these protocols, it
more accurately accounts for age-related reduction of
MHR. Be aware that the heart rate can be aected by
variables such as body temperature, hydration state,
anxiety, stress and medications. In addition to heart rate,
body mass (height-to-weight ratio), is also a signicant
variable in both prediction equations. The relation-
ship between height and weight is recorded as Body
Mass Index (BMI). It is important to note that BMI is not
being used in these aerobic protocols to estimate body
composition; but rather, is used to represent the mass of
each participant.
The test starts at 46 steps/min for 2 minutes, then 53
steps/min for 1 minute (warm-up period). The test
time includes the warm-up time. The test is a series of
1-minute intervals with increasing work loads on each
subsequent minute.
Note: Once the test starts, the user should not maintain a hold
or lean on the handrails; this will result in overestimation of
aerobic capacity.
The test is complete when the heart rate exceeds the
Target Heart Rate (THR) for 15 seconds. The total Test
Time (TT) begins from the time the user starts on the
StepMill, to the point at which the user exceeds their
THR. It does not include the nal 15 second qualication
period that the heart rate was above the THR.
The qualication period is to verify the user’s heart rate
does not exceed the target, and then drop down to the
THR or below for 15 seconds, if it does, then the test
continues.
