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 pedal, the console
will provide continuous exercise feedback. You can
even measure your heart rate using the built-in handgrip pulse sensor.
In addition, the console features two pulse programs
that change the resistance of the pedals and help you
to maintain a steady pedaling pace to keep your heart
rate near a target heart rate setting while you exercise.
The console also offers two preset 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.
To use the manual mode of the console, see the
instructions at the right. To use a pulse program, see
page 10. To use a preset program, see page 11.
Before using the console, make sure that batteries are
installed (see assembly step 6 on page 6). If there is a
sheet of clear plastic on the display, remove the plastic.

in the display (see the drawing above). Press the
Increase and Decrease buttons to change the
setting, if desired (see EXERCISE INTENSITY
on page 13). If the maximum target heart rate
setting is increased or decreased, the intensity
level of the entire program will increase or
decrease.
During the program, the console will regularly
compare your heart rate to the target heart rate
setting. If your heart rate is too far below or above
the target heart rate setting, the resistance of the
pedals will automatically increase or decrease to
being your heart rate closer to the target heart rate
setting. Note: If the resistance level is too high or
too low, you can override it by pressing the
Increase and Decrease buttons. However, when
the console compares your heart rate to the target heart rate setting, the resistance may automatically change.
After the first minute of the program, the pace
guide will help you to maintain a steady pedaling
pace. When one of the two lower indicators
lights, increase your pace; when one of the two
upper indicators lights, decrease your pace.
When the center indicator lights, maintain your
current pace. Important: The pace guide is

small amount of liquid dish soap. Important: To
avoid damage to the console, keep liquids away
from the console and keep the console out of
direct sunlight.
BATTERY REPLACEMENT
If the console display becomes dim, the batteries
should be replaced; most console problems are the
result of low batteries. To replace the batteries, see
assembly step 6 on page 6.
HOW TO ADJUST THE REED SWITCH
If the console does not display correct feedback, the
reed switch should be adjusted. To adjust the reed
switch, you must first remove the Left Side Shield (9).

CONDITIONING GUIDELINES
The following guidelines will help you to plan your
exercise program. Remember that proper nutrition
and adequate rest are essential for successful results.
WARNING: Before beginning
this or any exercise program, consult your
physician. This is especially important for
persons over the age of 35 or persons with
pre-existing health problems.
The pulse sensor is not a medical device.
Various factors may affect the accuracy of
heart rate readings. The pulse sensor is
intended only as an exercise aid in determining heart rate trends in general.
EXERCISE INTENSITY
Whether your goal is to burn fat or to strengthen your
cardiovascular system, the key to achieving the
desired results is to exercise with the proper intensity.
The proper intensity level can be found by using your
heart rate as a guide. The chart below shows recommended heart rates for fat burning, maximum fat
burning, and cardiovascular (aerobic) exercise.
During the first few minutes of exercise, your body
uses easily accessible
gy. Only after the first few minutes of exercise does
your body begin to use stored
If your goal is to burn fat, adjust the intensity of your
exercise until your heart rate is near the lowest number in your training zone as you exercise.
For maximum fat burning, adjust the intensity of your
exercise until your heart rate is near the middle of
your training zone as you exercise.
Aerobic Exercise
If your goal is to strengthen your cardiovascular system, your exercise must be “aerobic.” Aerobic exercise is activity that requires large amounts of oxygen
for prolonged periods of time. This increases the
demand on the heart to pump blood to the muscles,
and on the lungs to oxygenate the blood. For aerobic
exercise, adjust the intensity of your exercise until
your heart rate is near the highest number in your
training zone.
WORKOUT GUIDELINES
Each workout should include the following three parts:
carbohydrate
calories for ener-
fat
calories for energy.
To find the proper heart rate for you, first find your age
at the bottom of the chart (ages are rounded off to the
nearest ten years). Next, find the three numbers above
your age. The three numbers are your “training zone.”
The lowest number is the recommended heart rate for
fat burning, the middle number is the recommended
heart rate for maximum fat burning, and the highest
number is the recommended heart rate for aerobic
exercise.
Fat Burning
To burn fat effectively, you must exercise at a relatively low intensity level for a sustained period of time.
A warm-up, consisting of 5 to 10 minutes of stretching
and light exercise. A proper warm-up increases your
body temperature, heart rate, and circulation in preparation for exercise.
Training zone exercise, consisting of 20 to 30 minutes of exercising with your heart rate in your training
zone. Note: During the first few weeks of your exercise program, do not keep your heart rate in your
training zone for longer than 20 minutes.
A cool-down, with 5 to 10 minutes of stretching. This
will increase the flexibility of your muscles and will
help to prevent post-exercise problems.
EXERCISE FREQUENCY
To maintain or improve your condition, plan three workouts each week, with at least one day of rest between
workouts. After a few months of regular exercise, you
may complete up to five workouts each week, if
desired. Remember, the key to success is make exercise a regular and enjoyable part of your everyday life.
