Workout Window
The CYBER is equipped with Fisher’s patented
Workout Window™ feature. The
Workout Windowis a “computer within
your computer” that allows you to record a
second set of ride information (Speed,
Average Speed, Distance etc.) independent
from the normal operating modes. The
Workout Window allows you to easily separate the information for a race from the
information for your total ride so that you can
have an accurate picture of your racing or
training intensity.
TheWorkout
Window is easily
accessible from any
of the Cyber’s main
operating screens
simply by pressing
the Workout
Window Button.
NSTALLATION
Sensor and Wheel Magnet
1. Position the sensor unit to the inside of
either the right of left fork blade anywhere
from 3-6 inches up from the fork blade tip.
Attach the sensor to the fork blade with the
quick ties but do not tighten the ties completely
until final adjustment is complete.
2. Attach the wheel magnet to a spoke,
aligning the magnet with the sensor so it faces
and intersects the bottom polished line on the
sensor. The magnet should have 1-2 mm
clearance from the sensor. If the sensor and
magnet are too close or touching, rotate the
sensor unit toward the back of the fork blade
until adequate clearance is achieved. Carefully
tighten the quick ties making sure you maintain the proper space between the magnet
and the sensor. Trim the excess quick tie strap
using a scissors or fingernail clipper. Tighten
the magnet screw, but be careful not to over
tighten as this can damage the fitting.
Sensor Wiring and Bracket
1. Route the sensor wire up the back of the
fork blade or wind the wire around the blade,
making sure that the wire is not loose and
that you leave enough wire to reach the handlebar. Secure the wire to the fork blade
immediately above the sensor and at the top
of the fork blade, using the adhesive strips
that are provided or electrical tape.
2. Wind the wire upward around the front
brake cable until the wire is adjacent to the
handlebar, allowing enough slack for free
movement of the steering assembly cables.
3. Attach the bracket to the handlebar on
either side of the stem. The bracket goes onto
the handlebar with the wire toward the rider
side of the bar. Use the appropriate rubber
shim between the bracket and handlebar to
provide a secure fit.
Shims will
prevent slipping
Attaching the Computer to the Bracket
The Fisher Cyber Computer attaches to the
mounting bracket by sliding the unit onto the
bracket from the back until it snaps firmly
into position. To remove the computer from
the bracket, place your thumb against the
back of the mounting bracket and pull the
computer toward you with your index finger.
COMPUTER SET UP
Battery Installation

5. Press the MODE key to set the screen and
advance to setting the Minutes in the same
manner as Hours.
6. Press the MODE key one final time to set
the screen and return to the main screen .
Wheel Size Setting
The wheel size setting number is equal to the
distance, in millimeters, that your front wheel
travels during one complete revolution. Each
time the wheel magnet passes the sensor unit
on your fork, the sensor sends an impulse to
the computer telling it that your wheel has
completed one revolution. The computer calculates this distance vs. time to give you accurate readings for the various modes.
Determining Wheel Size Setting
There are three methods for determining the
wheel size setting. For the most accurate
computer readings, it is best to measure the
actual distance that your wheel travels in one
complete revolution. This method is called a
wheel roll out.
Method One: Wheel Roll Out
• Perform the wheel roll out on a hard, flat,
smooth surface such as a garage or
basement floor.
• Make sure your tires are properly inflated.
1. Position your bike so that the valve stem of
the front wheel is at its bottom most position.
Mark the spot on the floor directly under the
center of the valve stem using a piece of tape
or chalk.
2. Roll the bicycle forward in a straight line,
while putting downward pressure on the handlebars to simulate rider weight. When the wheel
has completed one revolution and the valve stem
is at its bottom position, mark the floor directly
under the center of the valve stem with tape or
chalk. Measure the distance between the two
marks in millimeters. (Note: Conversion of in. to
mm. is 1 in.=25.4 mm.) This is your wheel setting number. You can repeat this procedure and
average your results. We recommend that you
record your wheel setting numbers here for
future reference.
Method Two:
Measure wheel radius (including tire) in
mm and multiply by 6.2832=Wheel
setting number.
Method Three:
Refer to the following chart and input the
number that corresponds to your tire size.
(Note: Actual size of two similarly marked
tires from different manufactures can vary
significantly, making this method the least
accurate.)
