POWER
The bike has a built-in generator for power and
do not need to be plugged into an AC outlet.
To power up the bike simply start to pedal, the
console will turn on automatically.
When initially powered on, the console will
perform an internal self-test. During this time the
display may not light up for a few seconds.
Continue pedaling and the display will light up.
Once powered on, the Dot Matrix Message
Center will be scrolling the start-up message.
You may now begin your workout program.
C-SAFE FEATURE
Your console is equipped with a C-SAFE fea-
ture. The Power (POW-
ER) port can be used
for powering a remote
controlled audio-visual
system by connecting a
cable from the remote
to the Power port at the
back of the console. The Communication port
(COMM) can be used to interact with tness
software applications.
QUICK START
This is the quickest way to start a workout. After
the console powers up you just press the Start
key to begin. This will initiate the Quick Start
mode. In Quick Start the Time will count up
from zero, all workout data will start to accrue
and the workload may be adjusted manually
by pressing the Level Up and Down buttons.
The Dot Matrix Message Center display will
show just the bottom row lit. As you increase
the workload more rows will light indicating
a harder workout. The bike will get harder to
pedal as the rows increase. The Dot Matrix
Message Center has 24 columns of lights and
each column represents 1 minute. At the end
of the 24th column (or 24 minutes of work) the
display will wrap around and start at the rst
column again.
There are 40 levels of resistance – displayed

15
www.spirittness.com
as 10 rows of lights – available for plenty of
variety. The rst 10 levels are very easy work-
loads, and the changes between levels are
set to a good progression for de-conditioned
users. Levels 10-20 are more challenging but
the increases from one level to the next remain
small. Levels 20-30 start getting tough as the
levels jump more dramatically. Levels 30-40 are
extremely hard and are good for short interval
peaks and elite athletic training.
1/4 MILE TRACK
The 1/4-mile track (0.4 km) will be displayed
around the dot matrix window. The ashing dot
indicates your progress. In the center of the track
there is a lap counter for reference.
HEART RATE WINDOW
The Pulse (Heart Rate) window will display your
current heart rate in beats per minute during the
workout. You must use both left and right stainless
steel sensors to pick up your pulse. Pulse values are
displayed anytime the computer is receiving a Grip
Pulse signal. You may use the Grip Pulse feature
while in Heart Rate Control. The CU800 will also
pick up wireless heart rate transmitters that are
Polar compatible, including coded transmissions.
TO TURN BIKE OFF
The display will automatically turn off (go to sleep)
after 30 minutes of inactivity. This function is called
sleep mode. In sleep mode, the bike will power
down most everything except for a minimum
of circuitry for detecting button presses and the
safety button so it will start up again if these are
activated. There is only a tiny amount of current
used in sleep mode (about the same as your TV
when it is turned off) and it is perfectly ne to
leave the main power switch on in sleep mode.
Of course you may also remove the safety button
or turn off the main power switch to power down
the bike.
BASIC INFORMATION
The Dot Matrix Message Center, or Prole
Window, will display the workout Prole. The
LED Data Display Window displays pertinent
exercise data. There is a RPM window for

16
Spirit Fitness
pedal speed and a Level window indicating
machine resistance.
The LED Data Display Windows will initially be
displaying Distance, Calories,Pulse and Time
Elapsed information. When the Up/Down Scan
key is pressed the next set of information will
appear: Speed, Watts, METs, Time Remaining.
Pressing the Up/Down Scan button, the Scan
mode is activated and the LED Data Display
Window will show each set of data for four
seconds then switch to the next set of data in a
continuous loop. Pressing the Up/Down Scan
button again will bring you back to the begin-
ning.
The Stop key button actually has several func-
tions. Pressing the Stop key once during a
program will pause the program for 5 minutes.
If you need to get a drink, answer the phone,
or any of the many things that could interrupt
your workout, this is a great feature. To resume
your workout during Pause just press the Start
key. If the Stop key is pressed twice during a
workout, the program will end and the console
will return to the start-up screen. If the Stop key
button is held down for 3 seconds, the console
will perform a complete Reset. During data
entry for a program the Stop key performs a
Previous Screen function. This allows you to go
back one step in the programming each time
you press the Stop key button.
The Program Key is used to preview each
program. When you rst turn the console on,
you may press Program key to preview what
the program prole looks like. If you decide that
you want to try a program, press the Enter key
to select the program and enter into the data
set-up mode.
PROGRAMMING THE CONSOLE
Each of the programs can be customized with
your personal information and changed to suit
your needs. Some of the information asked for
is necessary to ensure the readouts are correct.
You will be asked for your Age and Weight.

17
www.spirittness.com
Your Age is also necessary during the Heart Rate control program to ensure the correct settings
are in the program for your Age. Otherwise the work settings could be too high or low for you;
entering your Weight aides in calculating a more correct calorie reading. Although we cannot
provide an exact calorie count we do want to be as close as possible.
CALORIE NOTE: Calorie readings on every piece of exercise equipment, whether it is in a gym
or at home, are not accurate and tend to vary widely. They are meant only as a guide to monitor
your progress from workout to workout. The only way to measure your calorie burn accurately is
in a clinical setting connected to a host of machines. This is because every person is different and
burns calories at a different rate.
ENTERING & CHANGING SETTINGS
When you enter a program, you have the option of entering your own personal settings. If you
want to work out without entering new settings, then just press the Start key. This will bypass the
programming of data and take you directly to the start of your workout. If you want to change the
personal settings, then just follow the instructions in the Dot Matrix Message Center. If you start a
program without changing the settings, the default, or pre-saved settings will be used.

yourself and not the computer. To start the Manual program follow the instructions below.
1. Using the Program button choose the Manual program then press the Enter button.
2. The Dot Matrix Message Center will ask you to enter your Age. You may enter your Age, using the Up

screen.
3. You are now asked to enter your Weight. You may adjust the Weight number using the Up and Down
buttons, then press enter to continue.
4. The next setting is Time. You may adjust the Time and press Enter to continue.
5. Now you are nished editing the settings and can begin your workout by pressing the Start button. You
can alsogo back and modify your settings by pressing the Enter button.
NOTE: At any time during the editing of data you can press the Stop button to go back one level, or
screen.
6. The program automatically starts you at level one. This is the easiest level and it is a good idea to stay
at level one for a while to warm up. If you want to increase the work load at any time press the Level
Up button; the Level Down button will decrease the workload.
7. When the program ends you may press Start to begin the same program again or Stop to exit the
program.
