FEATURES OF THE CONSOLE
The advanced console offers a selection of features
designed to make your workouts more enjoyable and
effective. When you use the manual mode of the con-
sole, you can change the resistance of the pedals with
the touch of a button. As you exercise, the console will
provide continuous exercise feedback. You can even
measure your heart rate using the handgrip pulse
sensor.
The console also offers two smart workouts that auto-
matically change the resistance of the pedals and
prompt you to increase or decrease your pace while
guiding you through an effective workout.
In addition, the console features two heart rate work-
outs that automatically change the resistance of the
pedals and prompt you to vary your pace to keep your
heart rate near a target heart rate while you exercise.
To use the manual mode, see page 13. To use a
smart workout, see page 15. To use a heart rate
workout, see page 16.
Note: If there is a sheet of clear plastic on the face of
the console, remove the plastic.

HOW TO USE THE MANUAL MODE
1. Press any button on the console or begin
pedaling to turn on the console.

the resistance of the
pedals by pressing the
Resistance increase or
decrease buttons.
Note: After you press
the Resistance, it will
take a moment for the pedals to reach the select-
ed resistance level.
4. Follow your progress with the displays.
The left display--will
show a track repre-
senting 1/4 mile (400
meters). As you exer-
cise, indicators will
appear in succession
around the track until
the entire track appears. The track will then disap-
pear and the indicators will again begin to appear
in succession.

5. Measure your heart rate if desired.
If there are sheets of
clear plastic on the
metal contacts on
the handgrip pulse
sensor, remove the
plastic. To measure
your heart rate, hold
the handgrip pulse
sensor, with your
palms resting against
the metal contacts. Avoid moving your hands or
gripping the contacts tightly.
increase or decrease your pedaling speed. Press
the Fan button 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 auto-
matically.
Slide the thumb tab on
the right side of the fan
to pivot the fan to the
desired angle.
When your pulse is detected, your heart rate will
be shown in the lower display. For the most accu-
rate heart rate reading, hold the contacts for at
least 15 seconds. Note: If you continue to hold the
handgrip pulse sensor, the lower display will show
your heart rate for up to 30 seconds. The display
will then show your heart rate along with the other
modes.
If your heart rate is not shown, make sure that
your hands are positioned as described. Be care-
ful not to move your hands excessively or to
squeeze the metal contacts tightly.
6. Turn on the fan if desired.

HOW TO USE A SMART WORKOUT
1. Press any button on the console or begin
pedaling to turn on the console.
A few seconds after the console is turned on, the
displays will light. A tone will then sound and the
console will be ready for use.
2. Select a smart workout.
To select a smart workout, press one of the Smart
Workouts buttons on the right of the console.
When you
select a smart

left display. In
addition, the
maximum resistance setting of the workout will
flash in the lower display for a moment and the
workout time will appear in the upper display.
3. Press the Workout Start button or begin
pedaling to start the workout.
Each workout is divided into 20 one-minute seg-
ments. One resistance setting and one pace set-
ting are programmed for each segment. Note: The
same resistance setting and/or pace setting may
be programmed for two or more consecutive seg-
ments.
During the workout, the workout profile will show
your progress (see the drawing above). The flash-
ing segment of the profile represents the current
segment of the workout. The height of the flashing
segment indicates the resistance level for the cur-
rent 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 differ-
ent resistance level is programmed for the next
segment, the resistance level will appear in the
display for a few seconds to alert you. The resis-
tance of the pedals will then change.
As you exercise, the
target pace guide will ._ GOSLOWER
help you to keep your
pedaling pace near the (_) TARGET
pace setting for the A GOFAS+E_
current segment. When
the "Go Faster" indica-
tor lights, increase your pace; when the "Go
Slower" indicator lights, decrease your pace; when
the "Target" indicator lights, maintain your current
pace.
IMPORTANT: The pace settings are intended
only to provide motivation. Your actual pace
may be slower than the pace settings. Make
sure to exercise at a pace that is comfortable
for you.
If the resistance level for the current segment is
too high or too low, you can manually override the
resistance level by pressing the Resistance but-
tons. However, when the current segment ends,
the resistance of the pedals will automatically
adjust to the resistance level programmed for the
next segment.
If you stop pedaling for several seconds, a series
of tones will sound and the workout will pause. To
restart the workout, simply resume pedaling. The
workout will continue until the last segment of the
workout ends.
4. Follow your progress with the displays.
See step 4 on page 13.
5. Measure your heart rate if desired.
See step 5 on page 14.
6. Turn on the fan if desired.
See step 6 on page 14.
.
When you are finished exercising, the console
will turn off automatically.
See step 7 on page 14.
