FEATURES OF THE CONSOLE
The advanced console offers an array of features
designed to make your workouts more effective and
enjoyable.
When you use the manual mode of the console, you
can change the resistance of the pedals with the touch
of a button. While you exercise, the console will display
continuous exercise feedback. You can also measure
your heart rate using the handgrip heart rate monitor.
The console offers a selection of onboard workouts.
Each workout automatically changes the resistance of
the pedals as it guides you through an effective work-
out. You can also set a calorie, distance, or time goal.
The console also features an iFit mode that enables
the console to communicate with your wireless network
through an optional iFit module. With the iFit mode,
you can download personalized workouts, create your
own workouts, track your workout results, race against
other iFit users, and access many other features.
To purchase an iFit module at any time, go to
www.iFit.com or call the telephone number on the
front cover of this manual.
You can even connect your MP3 player or CD player
to the console sound system and listen to your favorite
music or audio books while you exercise.
To use the manual mode, see this page. To use the
sound system, see page 19. To use an onboard
workout, see page 20. To use a set-a-goal work-
out, see page 21. To use an iFit workout, see page
22. To change console settings, see page 24.

As you pedal, change the resistance of the pedals
by pressing the Resistance increase and decrease
buttons or by pressing one of the numbered
Resistance buttons.
Note: After you press a button, it will take a
moment for the pedals to reach the selected resis-
tance level.
4. Follow your progress with the display.
The display can show the following workout
information:
Calories (Cals.)—This display mode will show the
approximate number of calories you have burned.
Calories per Hour (Cals./Hr)—This display mode
will show the approximate number of calories you
are burning per hour.

18
Distance (Dist.)—This display mode will show
the distance that you have pedaled in miles or
kilometers.
Pulse—This display mode will show your heart rate
when you use the handgrip heart rate monitor (see
step 5).
Resistance (Resist.)—This display mode will
show the resistance level of the pedals for a few
seconds each time the resistance level changes.
Speed—This display mode will show your pedaling
speed in miles per hour or kilometers per hour.
Time—When the manual mode is selected, this
display mode will show the elapsed time. When a
workout is selected, this display mode will show the
time remaining in the workout.
The matrix offers several display tabs. Press the
Display button until the desired tab is shown. You
can also press the increase and decrease buttons
next to the Enter button.
Speed—This tab will show a profile of the speed
settings of the workout. A new segment will appear
at the end of each minute.

1/4 mile (400 m). As you exercise, the flashing
rectangle will show your progress. The My Trail tab
will also show the number of laps you complete.
Calorie—This tab will show the approximate
amount of calories you have burned. The height of
each segment represents the amount of calories
burned during that segment.
As you exercise, the workout intensity level bar
will indicate the approximate intensity level of your
exercise.
When a wireless iFit module
is connected, the wireless
symbol at the top of the dis-
play will show the strength of
your wireless signal. Four arcs
indicate full signal strength.
To exit the manual mode or a workout, press the
Home button. If necessary, press the Home button
again.
Change the volume level of
the console by pressing the
volume increase and decrease
buttons.
5. Measure your heart rate if desired.

the hand-
grip heart
rate moni-
tor, remove
the plastic.
To measure
your heart
rate, hold the handgrip heart rate monitor with your
palms resting against the contacts. Avoid moving
your hands or gripping the contacts tightly.
When your pulse is detected, a heart symbol in the
calorie display will flash each time your heart beats,
one or two dashes will appear, and then your heart
rate will be shown. For the most accurate heart
rate reading, hold the contacts for at least 15
seconds.
Contacts

19
If the display does not show your heart rate, make
sure that your hands are positioned as described.
Be careful not to move your hands excessively or
to squeeze the contacts tightly. For optimal perfor-
mance, clean the contacts using a soft cloth; never
use alcohol, abrasives, or chemicals to clean
the contacts.
6. Turn on the fan if desired.
The fan has high and low
speed settings. Press the fan
increase and decrease but-
tons repeatedly to select a fan
speed or to turn off the fan.
Note: If the pedals do not move for about thirty
seconds, the fan will turn off automatically.
7. When you are finished exercising, the console
will turn off automatically.
If the pedals do not move for several seconds, a
tone will sound, the console will pause, and the
time will flash in the display. To resume your work-
out, simply resume pedaling.
If the pedals do not move for several minutes and
the buttons are not pressed, the console will turn
off and the display will be reset.
Note: The console features a display demo mode,
designed to be used if the exercise bike is dis-
played in a store. When the demo mode is turned
on, the console will show a preset presentation. To
turn off the demo mode, see HOW TO CHANGE
CONSOLE SETTINGS on page 24.
HOW TO USE THE SOUND SYSTEM
To play music or audio books through the console
sound system while you exercise, plug a 3.5 mm male
to 3.5 mm male audio cable (not included) into the jack
on the console and into a jack on your MP3 player,
CD player, or other personal audio player; make sure
that the audio cable is fully plugged in. Note: To
purchase an audio cable, see your local electronics
store.
Next, press the play button on
your personal audio player. Adjust

HOW TO USE AN ONBOARD WORKOUT
1. Begin pedaling or press any button on the
console to turn on the console.
When you turn on the console, the display will turn
on. The console will then be ready for use.
2. Select an onboard workout.
To select an onboard workout, press the Speed
button or the Calorie button repeatedly until the
desired workout appears in the display.
When you select an onboard workout, the display
will show the duration of the workout and the name
of the workout. A profile of the speed settings of the
workout will appear in the matrix.
The maximum resistance level and the maximum
speed for the workout will also appear in the
display.
3. Begin pedaling to start the workout.
Each workout is divided into one-minute seg-
ments. One resistance level and one target speed
is programmed for each segment. Note: The same
resistance level and/or target speed may be pro-
grammed for consecutive segments.
During the
workout,
the profile
on the
speed
tab will
show your
progress.
The flashing segment of the profile represents the
current segment of the workout. The height of the
flashing segment indicates the target speed for the
current segment.
At the end of each segment of the workout, a
series of tones will sound and the next segment of
the profile will begin to flash. If a different resis-
tance level and/or target speed is programmed for
the next segment, the resistance level and/or target
speed will appear in the display for a few seconds
to alert you. The resistance of the pedals will then
change.
As you exercise, you will be prompted to keep your
pedaling speed near the target speed for the cur-
rent segment. When an upward-pointing arrow
appears in the display, increase your pedal-
ing speed. When a downward-pointing arrow
appears, decrease your pedaling speed. When
no arrow appears, maintain your current pedaling
speed.
IMPORTANT: The target speed is intended only
to provide motivation. Your actual pedaling
speed may be slower than the target speed.
Make sure to pedal at a speed that is comfort-
able for you.
If the resistance level for the current segment is
too high or too low, you can manually override
the setting by pressing the Resistance buttons.
IMPORTANT: When the current segment of the
workout ends, the pedals will automatically
adjust to the resistance level programmed for
the next segment.
The workout will continue in this way until the last
segment ends. To stop the workout at any time,
stop pedaling. The time will flash in the display. To
resume the workout, simply resume pedaling.
4. Follow your progress with the display.
See step 4 on page 17.
5. Measure your heart rate if desired.
See step 5 on page 18.
6. Turn on the fan if desired.
See step 6 on page 19.
7. When you are finished exercising, the console
will turn off automatically.
See step 7 on page 19.
