HOW TO OPERATE THE EXERCISE CYCLE
HANDLEBAR OPERATION
The handlebars can be used in either the dual-action
mode, for both upper-body and lower-body exercise,
or the stationary mode, for pedaling exercise only.
Dual-action Mode
To convert the
handlebars to
the dual-
action mode,
the link arms
must be con-
nected to the
pedals. Refer
to drawing 1.
Lift the link
arms off the
lock rods.
Refer to draw-
ing 2. Pull the
link arms out-
ward against
the tops of
the red wash-
ers, while
pulling
against the
bottoms of the
red washers
with your fin-
gers as shown. Be care ul not to pinch your in-
gers. Next, slide the link arms onto the pedal bush-
ings. Move the link arms up and down slightly to
make sure that they are fully seated on the pedal
bushings. CAUTION: Make sure that the link arms
are ully seated on the pedal bushings. I the link
arms are not on the pedal bushings, they may slip
o during use, resulting in injury to the user.
Stationary Mode
To convert the handlebars to the stationary mode, the
link arms must be disconnected from the pedals. Pull
the link arms outward against the red washers until
the link arms are free of the pedal bushings (see
drawing 2 above). Be care ul not to pinch your in-
gers. Next, lift the link arms off the pedals, and clip
them onto the lock rods (see drawing 1 above).
HOW TO ADJUST THE SEAT
For effective exer-
cise, the seat must
be at the proper
height. As you
pedal, there should
be a slight bend in
your knees when
the pedals are in
the lowest position.
To adjust the seat,
first turn the seat
knob counterclock-
wise two or three
turns to loosen it.
Next, pull the seat
knob, raise or lower the seat post, and then release
the seat knob. Move the seat post up and down
slightly until it locks into position. Then, tighten the
seat knob. CAUTION: Make sure that the pin on the
seat knob is inserted into one o the adjustment
holes in the seat post. Do not rest the seat post
on top o the pin on the seat knob.
DESCRIPTION OF THE CONSOLE
The console features six modes that provide instant
exercise feedback during your workouts. The modes
are described below.
• Time—This mode displays the elapsed time.
• Distance—This mode displays the total distance you
have pedaled.
• Speed—This mode displays your pedaling speed.
Note: Speed and distance can be displayed in either
miles or kilometers. An MPH or a KPH will appear
when the speed is displayed to show which unit of
measurement is selected. To change the unit of
measurement, press and hold the On/Reset button
for ten seconds.
• Calories—This mode displays the approximate num-
ber of calories you have burned.
• Fat calories—This mode displays the approximate
number of fat calories you have burned (see FAT
BURNING on page 12).
• Pulse—This mode displays your heart rate when the
thumb pulse sensor is used (see step 3 on page 10).

BATTERY INSTALLATION
The console requires four “D” batteries. To install bat-
teries, refer to assembly step 5 on page 7.
HOW TO OPERATE THE CONSOLE
Note: If there is a piece of clear plastic on the face of
the console, remove it before operating the console.
1. To turn on the
power, press
the On/Reset
button or begin
pedaling.
2. Begin exercising and monitor your progress with the
two displays.
Left display—
This display
shows the
elapsed time
and the dis-
tance that you
have pedaled.
The display will
change from
one number to the other every seven seconds, as
shown by the indicators in the display.
Right display—
This display
shows your
pedaling speed
and the approx-
imate numbers
of calories and
fat calories you
have burned.
When the thumb pulse sensor is used, the display
will also show your heart rate (see step 3 at the
right). Every seven seconds, the display will change
from one number to the next, as shown by the indi-
cators in the display.
To reset the displays at any time, press the
On/Reset button.
3. Measure your heart rate, if desired.
To measure
your heart rate,
stop pedaling
and place your
thumb on the
pulse sensor as
shown. The
pulse sensor is
pressure activat-
ed—fully press it down. Do not press too hard, or
the circulation in your thumb will be restricted,
and your pulse will not be detected. Next, raise
your thumb slightly until the heart-shaped indicator
in the right display flashes steadily. Hold your
thumb at this
level. After a few
seconds, two
dashes will
appear in the
display, and
then your heart
rate will be
shown. Hold
your thumb on
the pulse sensor for another 15 seconds for the
most accurate reading. If the displayed heart rate
appears to be too high or too low, or if your heart
rate is not displayed, lift your thumb off the pulse
sensor and allow the display to reset. Press down
again on the pulse sensor as described above.
Make sure that you are applying the proper amount
of pressure to the pulse sensor. Try the pulse sensor
several times until you become familiar with it.
Remember to sit still while measuring your heart
rate.
4. To turn off the power, simply wait for a few minutes.
The console has an “auto-o ” eature. I the
pedals are not moved and the On/Reset button
is not pressed or a ew minutes, the power will
turn o automatically to conserve the batteries.
