slide the seat carriage to the desired position.
Release the seat knob and slide the seat carriage
back and forth slightly until it locks into position.

FEATURES OF THE CONSOLE
The advanced console offers a selection of features
designed to make your workouts more enjoyable and
effective. When the manual mode of the console is
selected, the resistance of the pedals can be changed
with the touch of a button. As you exercise, the con-
sole will provide continuous exercise feedback. You
can even measure your heart rate using the handgrip
pulse sensor.
The console also offers eight workout programs. Each
program automatically changes the resistance of the
pedals and prompts you to increase or decrease your
pedaling pace as it guides you through an effective
workout.
In addition, the console features new iFIT.com interac-
tive technology. Having iFIT.com interactive technology
is like having a personal trainer in your home. Using a
stereo audio cable (available at electronics stores), you
can connect the exercise cycle to your home stereo,
portable stereo, computer, or VCR and play special
iFIT.com CD and video programs (iFIT.com CDs and
videocassettes are available separately). iFIT.com CD
and video programs automatically control the resis-
tance of the pedals and prompt you to vary your pace
as a personal trainer coaches you through every step
of your workout. High-energy music provides added
motivation. To purchase iFIT.com CDs and video-
cassettes, call toll-free 1-800-735-0768.
With the exercise cycle connected to your computer,
you can also go to our Web site at www.iFIT.com and
access programs directly from the internet. Explore
www.iFIT.com for more information.
Note: If there is a sheet of clear plastic on the face of
the console, remove it before using the console.
