FEATURES OF THE CONSOLE
The easy-to-use console is designed to help you get
the most from your workouts. As you exercise, the
console will display the following modes:
Time—This mode displays the elapsed time (or the
time remaining in a pace program). Note: If you stop
pedalling, the time will begin to flash.
Distance—This mode displays the distance that you
have pedalled.
Calories—This mode displays the approximate number
of calories you have burned.
Fat calories—This mode displays the approximate
number of fat calories you have burned (see FAT
BURNING on page 13).
Pulse—This mode displays your heart rate when you
use the pulse sensor.
Speed—This mode displays your pedalling speed.
Scan—When this mode is selected, the upper section
of the display will show both the speed mode and the
distance mode, and the lower left section of the display
will show both the calories mode and the fat calories
mode.
The console also offers four pace programs. Each pro-
gram automatically prompts you to increase or
decrease your pace as it guides you through an effec-
tive workout.
HOW TO USE THE MANUAL MODE
Turn on the console.
To turn on the console, press the On/Reset button
or begin pedalling. Note: If there is a sheet of clear
plastic on the console, remove it.

right contacts and your left palm covering the two
left contacts. Avoid moving your hands. When
your pulse is detected, the heart-shaped indicator
in the display will flash each time your heart
beats and two dashes (– –) will appear. After a
moment, your heart rate will be shown. For the
most accurate heart rate reading, continue to hold
the handgrips for about 15 seconds.
When you are finished exercising, the console
will automatically turn off after a few minutes.
If the pedals are not moved and the console but-
tons are not pressed for a few minutes, the con-
sole will automatically turn off to conserve
the batteries.
HOW TO USE A PACE PROGRAM
Turn on the console.
See step 1 on page 9.
Select one of the four pace programs.
Each time the
console is
turned on, the
manual mode
will be selected.
To select a pace
program, press
the Program
button repeated-
ly until the number 1, 2, 3, or 4 appears in the
upper right corner of the display.
The four profiles on the right side of the console
show how the target pace will change during the
programs. For example, profile number 1 shows
that during program 1, the target pace will
increase near the beginning of the program, and
then decrease near the end.
Start the program.
To start the program, begin pedalling. Each pro-
gram consists of either 20 or 30 one-minute peri-
ods. One target pace is programmed for each
period. Note: The same target pace setting may
be programmed for two or more consecutive peri-
ods.
The target pace
settings for the
program will be
shown by the
target pace indi-
cator in the dis-
play. (The pace
indicator will
show your actu-
al pedalling
pace.) As the
target pace indi-
cator changes in height during the program,
adjust your pedalling pace so that both indicators
are at the same height. If your pedalling pace is
slower than the current target pace setting, an
arrow will appear next to the pace indicators to
prompt you to increase your pace; if your pace is
faster than the target pace, an arrow will prompt
you to decrease your pace.

small amount of mild detergent. mportant: 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
step 5 on page 5 and remove the console from the
handlebar. Next, see step 4 on page 5 and insert
three batteries into the console. Reattach the console
to the handlebar, being careful not to pinch the wires.

COND T ON NG GU DEL NES
The following guidelines will help you to plan your
exercise program. Remember that proper nutrition
and adequate rest are essential for successful results.
EXERC SE NTENS TY
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 recom-
mended heart rates for fat burning, maximum fat
burning, and cardiovascular (aerobic) exercise.
To find the proper heart rate for you, first find your age
near 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 recom-
mended heart rate for maximum fat burning; the high-
est number is the recommended heart rate for aerobic
exercise.
Fat Burning
To burn fat effectively, you must exercise at a relative-
ly low intensity level for a sustained period of time.
During the first few minutes of exercise, your body
uses easily accessible carbohydrate calories for ener-
gy. Only after the first few minutes of exercise does
your body begin to use stored fat calories for energy.
If your goal is to burn fat, adjust the intensity of your
exercise until your heart rate is near the lowest num-
ber in your training zone as you exercise. For maxi-
mum fat burning, adjust the intensity of your exercise
until your heart rate is near the middle number in your
training zone as you exercise.
Aerobic Exercise
If your goal is to strengthen your cardiovascular sys-
tem, your exercise must be “aerobic.” Aerobic exer-
cise 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 GU DEL NES
Each workout should include the following three parts:
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 prepa-
ration for exercise.
Training zone exercise, consisting of 20 to 30 min-
utes of exercising with your heart rate in your training
zone. Note: During the first few weeks of your exer-
cise 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.
EXERC SE FREQUENCY
To maintain or improve your condition, plan three work-
outs 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 exer-
cise a regular and enjoyable part of your everyday life.
WARN NG:
• Before beginning this or any exercise pro-
gram, consult your physician. This is espe-
cially 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 deter-
mining heart rate trends in general.
