HEART RATE FEATURE
Safety Guidelines
Before using the Octane Fitness PRO4500 with HeartLogic™ Intelligence, read and follow these instructions:
Contact Heart Rate Grips
• Clean the contact heart rate grips periodically to remove sweat and oils. Use a damp cloth with a mild
detergent. Do not spray the hand grips directly with water or a cleaner; this could cause an electrical
short.
• When holding the grips, grasp each contact heart rate grip so the contact sensor portion of the grip rests
in the palm of your hand. Grip the contact sensors firmly, and keep your hands steady and in place.
Wireless Chest Strap
• Do not allow users to use the chest strap if they have a cardiac pacemaker or are taking
prescription medication. Medication or electrical impulses from the cardiac pacemaker can cause
inaccurate heart rate readings.
• Please take care in handling the equipment as it is extremely sensitive.
• Do not bend the strips inside the chest strap as it can cause the strap to lose its conductivity.
• Handle the Octane Fitness heart rate transmitter (chest strap) with care. Dropping the transmitter might
cause damage and this could void the warranty.
• If the receiver (console) tries to process several signals simultaneously, an incorrect heart rate reading
could result. In a commercial setting, space the products at least 24” apart. This will prevent cross-talk,
where the chest strap signal from a user on one machine can be received and displayed on the console of
another machine.
• Do not place the chest strap near devices that generate large magnetic fields. Television sets, electric
motors, radios, and high voltage power lines can affect the transmitter’s performance. These items can
interfere with the heart rate signal that is being transmitted to the receiver, possibly affecting the heart
rate readings that appear on the electronic console.
• Do not immerse the transmitter in water. However, some moisture is necessary for the transmitter to
function properly. Perspiration is usually sufficient, but you may need to moisten the electrodes with a
small amount of water. The electrodes are the ribbed portion on the side of the transmitter that sits against
your skin.
• The Octane Fitness chest strap has a battery which may need to be replaced from time to time. A faulty
battery or worn electrodes may cause inaccurate readings. The electrodes are the ribbed portion on the
side of the transmitter that sits against your skin.
• To purchase wireless transmitter straps, contact your dealer or Octane Fitness sales representative.
Some individuals are unable to use the heart rate feature because they do not have the proper body chemistry
to provide accurate readings. If you experience difficulties in using the contact heart rate grips or a wireless
chest strap, contact your dealer or Octane Fitness Customer Service at 1.888.OCTANE4.

ELECTRONICS
PRO4500 CONSOLE
Welcome to some of the easiest to use, yet most sophisticated, electronics available in the fitness industry!
Programming the console DedicatedLogic™programming was created to give you the ultimate in ease of
use and total flexibility for programming your console. This allows you to modify
your workout once you’ve started. You can even start your workout, then program
the electronics. This ease of use starts by giving each key only one function. This
makes it easy to understand how each key works.
Getting started is easy—just hop on and start pedaling, or press any key. The
matrix display prompts you to select a program. Once a program is selected, the
console display will guide you through the steps to program your workout. After
each prompt, simply enter the requested data and press enter, and you are on
your way. If no values are entered at the prompts, the machine defaults to the
manual program at resistance level 1 with a stride length of 21” (54 cm) and a
user weight of 150 pounds.
CSAFE Programming The PRO4500 is CSAFE compatible. If you have connected the PRO4500 to your
CSAFE network, the user is prompted to enter a 5-digit User ID. The CSAFE user
has 30 seconds to enter the User ID digits by pressing the +/- keys to change a
digit and the Enter key to move to the next number in the ID. Once the ID has
been entered, the display proceeds with prompting the user for program set-up.
If no User ID or program is entered, the machine defaults to the manual program
at resistance level 1 with a stride length of 21” (54 cm) and a user weight of 150
pounds.
Console Buttons
Quick Start Press the Quick Start button to bypass the prompted programming and begin a
30-minute manual program at resistance level 1. Your calories will be based on
a 150 lb. (68 kg) user. Once you have selected Quick Start you can program any
console function at any time and any order.
Pause/Clear Press the Pause/Clear button once to pause your workout or simply quit pedaling.
The display will remain on for 10 seconds, and the CSAFE-compatible audio (if
installed) will remain on for 1 minute. Your workout values will be saved for two
minutes. To resume a paused workout, push any key or start pedaling. Press
Pause/Clear twice within two seconds to clear your workout.
SmartStride SmartStride automatically replicates natural movement by analyzing and
measuring the exerciser’s pace and direction and intuitively adjusting stride
length in 1 inch (2 centimeter) increments, from 18 inches (46 cm) to 23 inches
(58 cm). Press the SmartStride button and the machine will analyze your speed
for 10 seconds and make the appropriate adjustments. To deactivate SmartStride,
simply push the SmartStride button a second time.

2
ArmBlaster ArmBlaster is a proprietary program designed to boost cardiovascular endurance
while building strength and muscle tone. Press the ArmBlaster button at any time
during your workout to integrate cardio sessions with strength sessions. The
cardio session follows the program profile that you have selected. Every three
minutes, resistance increases 10 levels (or to the maximum resistance of 30)
for a muscle-building, 10-repetition set as you transfer the workload from your
lower body to your upper body. During the ArmBlaster rep countdown, the level
of resistance can be changed by pressing the Level (+/-) buttons. To deactivate
ArmBlaster, simply press the ArmBlaster button a second time.
X-Mode+X-Mode+is a great way to take advantage of the variety your elliptical cross
trainer offers. Press the X-Mode+button within any program, and a combination
of one to four randomly-generated X-Mode+LEDs will light up instructing you
what to do. Each X-Mode+session lasts for one minute with a two-minute
“regular” program routine in between. The PRO4500 offers eight different X-
Mode+challenges: Push Arms, Lower Body Only, Fast, Pull Arms, Squat, Slow,
Reverse and Lean Back. To deactivate X-Mode+, simply press the X-Mode+button
a second time.
GluteKicker GluteKicker is an aggressive subset of X-Mode+that is focused on your glutes,
hips, and thighs. It uses four prompts: reverse, squat, fast, and lean back.
GluteKicker sessions last for one minute, with a one minute recovery period.
Up and Down Keys
Time (+ and –) Increases or decreases the time for your workout (minutes:seconds). You can
change your time during a workout without having to restart the entire program.
The maximum workout time is 99 minutes; however, this can be customized for
your environment using the User Set-Up Functions described on page 20.
Program (+ and –) Toggles through programs. Program changes can be made any time during your
workout.
Stride (+ and –) Increases or decreases stride length. Each key press equals one inch (English)
or three centimeters (metric). The stride length ranges from 18 inches (46 cm) to 23
inches (58 cm). The default stride length for preset resistance and heart rate controlled
programs is 21” (54 cm). For variable stride programs, the default forward or long stride
is 21” (54 cm) and the default backward or short stride is 18” (46 cm).
Level (+ and –) Increases or decreases the resistance level of the machine. There are 30 levels
of resistance for programs P1-P5 and P11-P15. During heart rate programs (P6-
P10), the Level button increases or decreases your target heart rate. (For more
information on heart rate programs, go to page 8). To save a change in target
heart rate, you must hit Enter after entering the proper number.
Weight (+ and –) Increases or decreases the user’s entered weight. This value is used to give a
more accurate calorie burn readout. Weight is displayed in pounds (English) or
kilograms (metric). You can change this setting from English to metric or metric to
English, using the User Set-Up Functions described on page 20.

3
Age (+ and –) Used for heart rate programs. Entering an age will give a recommended target
heart rate based on the formula 220 – your age = your theoretical maximum
heart rate (TMHR). That number is then multiplied by the program intensity value
to determine your target heart rate(s). If you are not in a heart rate controlled
program, but want to see your heart rate percentage, just enter your age. (You
must be wearing your wireless heart rate transmitter or grasping the contact
heart rate sensor grips to use this feature.) For more information, refer to page
23, “What should my heart rate be?”.
Enter Selects any of the changed values or items from the above keys. Also, pressing
the Enter key during any workout will stop the LED readout windows from
toggling between display modes.

Manual The Manual program simulates walking or jogging on a flat surface. The manual
program does not have a warm-up. To begin the program, you are prompted
to enter your workout time, stride length, level, and weight. The resistance
stays constant for the entire workout, unless you change it by pressing
Level (+/–). The oval racetrack signifies 1/4 mile (or 1/4 kilometer); a counter
shows how many laps you have completed during your workout. The default
stride length is 21” (54 cm). The stride length and resistance can be changed any
time during the workout.
Random The Random program has a virtually infinite number of different combinations.
The computer randomly generates a new course each time you select the random
program, giving you different levels of resistance. Each column on the display
lasts for 1 minute. To begin the program, you are prompted to enter your workout
time, stride length, level, and weight.
PRO4500 PROGRAMS AND FEATURES
Program Warm-up
Programs begin with a warm-up to ease your body into your intense workout. During the warm-up, the
resistance and stride length increase each minute.
Programs P2-P5 and P11-P15 incorporate a three-minute warm-up (unless you have deactivated the
warm-up feature using the User Set-up Functions described on page 20). Resistance increases two levels
per minute and stride length increases 1 inch (2 cm) per minute. In heart rate controlled programs (P6-P10),
increasing or decreasing the Level changes the target heart rate. Stride length increases 1 inch (2 cm) per
minute until reaching your entered stride length. The warm-up lasts three minutes or until you reach your
target heart rate; then your selected program begins.
Preset Resistance Programs
Manual—Random—Interval—Hill—10K
Level

6
Interval The Interval program alternates between two different levels of resistance. Each
level is independently adjustable, so you can customize the amount of change
between the two intervals. All intervals have a two-minute duration. To begin the
program you are prompted to enter your workout time and stride length. Then,
“SET 1ST INTERVAL” scrolls across the matrix display and the resistance level
for this interval is shown in the “Level” window. The standard level for the first
interval is “1”. Use Level +/- while “SET 1ST INTERVAL” is scrolling across
the matrix display to set your desired first interval resistance level. Next, “SET
2ND INTERVAL” scrolls across the matrix display and the resistance level for
this interval is shown in the “Level” window. The standard level for the second
interval is “4”. Use Level + /- while “SET 2ND INTERVAL” is scrolling across the
matrix display to set your desired second interval resistance level. Finally, you
will be asked to enter your weight. Once you are pedaling and your warm-up is
complete, you can increase or decrease the level of the current interval (1st or
2nd) at any time by pressing the Level +/– buttons. The value of the other interval
does not change. The value you enter changes only the current interval (1st or 2nd)
for the entire remaining workout, or until you change it again.
Hill The Hill program simulates walking or jogging up a big hill. To begin the program
you are prompted to enter your workout time, stride length, level, and weight.
The resistance increases and the climb level will get more difficult the closer you
get to the top of the “hill”. Increasing or decreasing the resistance level changes
all plateaus and hills for the entire program. The resistance change between
the plateaus is computer controlled. Each hill lasts for two minutes, with a
30-second recovery session at lower resistance between hills. After you climb
the highest hill, you have a 30-second recovery session before the sequence
begins again with the lowest hill. These recovery sessions give your body a quick
break, allowing you to take in more oxygen and letting your muscles take a break
while your heart continues to beat at a higher pace. This approach lets you hit
higher resistance levels for shorter periods, giving you an interesting workout as
you build strength and endurance.

7
10K 10K simulates jogging or running outdoors. It is a great training device to get
ready for a competition. To begin the program you are prompted to enter your stride
length, level, and weight. After you complete the warm-up, the changes in terrain
replicate the challenges you encounter running outside. You can feel going uphill
and downhill with gradual resistance changes. The distance readout will count
down from 6.2 miles (10 kilometers). To end your workout, press Pause/Clear or
just stop pedaling. If you desire, you can continue your workout after you have
completed the 6.2 miles (10 kilometers) distance.

8
Heart Rate Interval The Heart Rate Interval program puts you through intervals of 70% and 80% of
your theoretical maximum heart rate (TMHR). Interval training has been shown
to give superior results compared to steady state training (that is, training at
a constant resistance level). Each interval lasts for two minutes. To begin the
program you are prompted to enter your workout time, stride length, age, and
high (80%) target heart rate. The display shows your 80% heart rate based on
the age you entered, but you can increase or decrease this value using the Level
(+/-) keys. The program sets your initial low (70%) target heart rate value based
on the value you enter for the high target heart rate. After the warm-up, the
resistance increases or decreases at the end of each two-minute period to get
you to the next interval. When you reach the new target heart rate, the new two
minute interval begins. The display will prompt you to increase or decrease your
Cardio The Cardio program guides your workout to maximize cardiovascular benefits,
like training for a race. The recommended target heart rate is 80% of your
theoretical maximum heart rate (TMHR = 220 – age). To begin the program
you are prompted to enter your workout time, stride length, age, target heart
rate, and weight. The program starts with a three-minute warm-up. During the
warm-up you can change your target heart rate using the Level (+/–) buttons.
After the warm-up, the resistance will automatically adjust to keep you working
out at your target heart rate. If you reach your target heart rate during the
warm-up, the warm-up ends and the heart rate control portion begins.
Example for a 40-year-old person:
220 – 40 yrs. old = 180 TMHR
180 *.80 = 144 Target heart rate
Fat Burn The Fat Burn program guides your workout to maximize the percentage of calo-
ries burned from fat vs. carbohydrates. The recommended target heart rate is
65% of your theoretical maximum heart rate (TMHR = 220 – age). To begin the
program you are prompted to enter your workout time, stride length, age, target
heart rate, and weight. The program starts with a three-minute warm-up. During
the warm-up you can change your target heart rate using the Level (+/–) buttons.
After the warm-up, the resistance will automatically adjust to keep you working
out at your target heart rate. If you reach your target heart rate during the warm-
up, the warm-up ends and the heart rate control portion begins.
Example for a 40-year-old person:
220 – 40 yrs. old = 180 TMHR
180 *.65 = 117 Target heart rate
Heart Rate Controlled Programs
Fat Burn - Cardio - Heart Rate Interval - Heart Rate Hill - Heart Rate Speed Interval

9
Heart Rate Hill Heart Rate Hill takes you through a series of hills which increase in intensity
from 65% to 75% to 85% of your theoretical maximum heart rate (TMHR). Each
hill lasts for two minutes. To begin the program you are prompted to enter your
workout time, stride length, age, and high (85%) target heart rate. The display
shows your 85% heart rate based on the age you entered, but you can increase
or decrease this value using the Level (+/-) keys. The program sets your initial
medium (75%) and low (65%) target heart rate values based on the value you
enter for the high target heart rate. After the warm-up, the resistance increases
or decreases at the end of each two-minute period to get you to the next hill.
Once you reach the new target heart rate, the new two-minute hill begins. The
display will prompt you to increase or decrease your effort until the desired heart
rate is reached. Each intensity level is independently adjustable by pressing the
Level (+/-) buttons and pressing Enter. Pressing Level (+/-) will change your target
heart rate. The better your physical condition, the more hills you will be able to
accomplish in the same period of time. The program starts with a three minute
warm-up. During the warm-up, you can change your high target heart rate using
the Level (+/–) buttons. If you reach your target heart rate during the warm-up,
the warm-up ends and the heart rate control portion begins.
Example for a 40-year-old person:
220 – 40 yrs. old = 180 TMHR
180 *.65 = 117 Low hill target heart rate
180 *.75 = 135 Medium hill target heart rate
180 *.85 = 153 High hill target heart rate
effort until the desired heart rate is reached. Each interval target heart rate level
is independently adjustable by pressing the Level (+/-) buttons and pressing Enter.
Pressing Level (+/-) will change your target heart rate. The better your physical
condition, the more intervals you will be able to accomplish in the same period of
time. The program starts with a three-minute warm-up. During the warm-up, you
can change your high target heart rate using the Level (+/–) buttons. If you reach
your target heart rate during the warm-up, the warm-up ends and the heart rate
control portion begins.
Example for a 40-year-old person:
220 – 40 yrs. old = 180 TMHR
180 *.70 = 126 Low interval target heart rate
180 *.80 = 144 High interval target heart rate

10
Heart Rate The Heart Rate Speed Interval program puts you though intervals of 65% and
85% of your theoretical maximum heart rate (TMHR). It combines steeper
intervals with changing speeds. Interval training has been shown to give superior
results compared to steady state training (that is, training at the same resistance
level). Each interval lasts for one minute. To begin the program you are prompted
to enter your workout time, stride length, age, and high (85%) target heart rate.
The display shows your 85% heart rate based on the age you entered, but you
can increase or decrease this value using the Level (+/-) keys. The program sets
your initial low (65%) target heart rate value based on the value you enter for
the high target heart rate. The resistance increases or decreases at the end of
each minute to get you to the next interval. When you reach the new target heart
rate, the new interval begins. When going from the lower interval to the higher
interval, the electronics instruct you to speed up to get there faster. When you are
going from the higher interval to the lower interval, the electronics instruct you
to slow down to decrease your heart rate to the new lower target more quickly.
Each interval intensity is independently adjustable. To change the target heart
rate, press the Level (+/–) buttons. This will change the intensity level for the
entire interval. The better your physical condition, the more intervals you will be
able to accomplish in the same period of time. The program starts with a three
minute warm-up. During the warm-up, you can change your high target heart
rate using the Level (+/–) buttons. If you reach your target heart rate during the
warm-up, the warm-up ends and the heart rate control portion begins. For the
ultimate workout, use SmartStride in combination with Heart Rate Speed Interval
varying both resistance and stride length throughout your workout.
Example for a 40-year-old person:
220 – 40 yrs. old = 180 TMHR
180 *.65 = 117 Low interval target heart rate
180 *.85 = 153 High interval target heart rate

Variable Stride Programs
Starter - PowerWalk - Stride Interval - Dual Direction - Stride Burst
Starter The Starter program is a great routine for beginners or people just getting back
into their workouts. This program is designed to carry you through 10 workouts,
one per day, gradually increasing intensity each day. Each day’s workout includes
a preset value for time, resistance level, stride length, and a recommended speed
(RPM). To begin the program you are prompted to enter your workout time and
the program level, which is the same as the day. Use Level (+/-) to select the day,
and the preset values will be displayed in the corresponding windows. The preset
values can be changed during the workout.
Program Day (Level) 1 2 3 4 5 6 7 8 9 10
Resistance Level 1 1 1 1 2 2 2 2 3 3
Stride Length 18 18 19 19 19 20 20 20 20 21
Time 10 11 12 13 14 15 16 17 18 20
RPMs 30 35 35 35 40 40 40 40 40 40
PowerWalk The PowerWalk program combines high resistance/short stride and lower
resistance/long stride intervals in order to closely simulate the feel of hiking
uphill and downhill. Each interval is two minutes long. The low resistance/long
stride interval is great for lower-body full range of motion. The high resistance
short stride session decreases leg activity while putting intense strength-building
requirements on the upper body. To begin the program, you are prompted to enter
your workout time. Then, the displays will prompt you to select the long and
short stride lengths. Finally, you will be asked to enter the high resistance level.
The default level is 5, but you can increase or decrease it by pressing the Level
(+/-) buttons. The initial low resistance/long stride interval level equals the high
resistance/short stride minus 4 levels (low resistance/long stride interval = high
resistance/short stride level – 4 levels). During the workout, the level and stride
length can be independently changed for the interval by pressing the Level (+/-)
buttons. However, the lower level cannot be set above the higher level, and the
higher level cannot be set below the lower level.

12
Stride Burst The Stride Burst program alternates one-minute long stride, higher resistance
intervals with two-minute shorter stride, lower resistance recovery intervals. To
begin the program, you are prompted to enter your workout time, the long and
short stride lengths, and the high resistance (for the long stride interval). The
default resistance level is 5, but you can increase or decrease it by pressing the
Level (+/-) buttons. The initial shorter stride interval resistance level equals the
longer stride interval minus 4 levels (short stride interval = long stride interval
level – 4 levels). During the workout, the stride length and/or resistance level can
be changed for the interval by pressing the Level (+/-) buttons. However, short
stride cannot be longer than the long stride, and low resistance cannot be higher
than high resistance. Changed settings apply for the remainder of the workout
(unless you change them again). (Refer to the program profile on the following
page.)
Stride lnterval The Stride Interval program alternates shorter stride intervals and longer stride
intervals. Each interval is two minutes long. Resistance remains constant during
the workout. To begin the program you are prompted to enter your workout time,
the lengths of the long and short strides, level, and weight. During the workout,
the stride length and/or resistance intervals can be changed for the interval by
pressing the Level (+/-) buttons. However, short stride cannot be longer than the
long stride, and low resistance cannot be higher than high resistance. Changed
settings apply for the remainder of the workout (unless you change them again).
Dual Direction The Dual Direction program alternates two-minute forward intervals with
one-minute, lower resistance backward intervals. To begin the program, you are
prompted to enter your workout time, the forward and backward stride lengths,
and the high resistance (for the forward interval). The default high resistance
level is 5, but you can increase or decrease it by pressing the Level (+/-) buttons.
The backward interval level is initially set to the forward interval minus 4 levels
(backward interval = forward interval level – 4 levels). During the workout, the
level and stride length can be independently changed for an interval by pressing
the Level (+/-) buttons. However, reverse stride can not be longer than forward
stride, and low resistance can not be higher than high resistance. Changed
settings apply for the remainder of the workout (unless you change them again).
