2004 TURBO®PRO
CYCLOCOMPUTER

Congratulations on your purchase! You are now the
owner of the world’s most advanced cyclocomputer.
Your Specialized Turbo® Pro features a wireless speed
transmitter and a wired cadence sensor. Additionally, it
incorporates a revolutionary new backlit three-line LCD
screen. The large, easy to read, digits allow you to view
two functions simultaneously and the alphanumeric dot
matrix display provides a quick reference to the currently
displayed function. The Turbo® Pro has been designed
to provide the best combination of performance,
features, durability and ease of use.

Turn the computer over so
the display is facing
downward. Use a coin to
unthread the battery cap
from the computer. Install
the battery (model
CR2032, Specialized
P/N 481-3004) with the
positive pole (+) facing
upward. Carefully thread
the battery cap back onto
the case with a coin. (See
Figure 3) If, after battery
replacement, the LCD dis­play is blank or shows
incomplete digits, turn the
computer over and press
the “AC” button on the
bottom of the case with
the tip of a pen or a

paper clip. This will clear
all the data and re-start
the computer. If you need
to replace the battery,
make a note of your
odometer reading and
wheel circumference set­tings before removing it.
You can then re-enter the
data when you restart the
computer.

Replacing the Transmitter
Battery

The Wireless Transmitter
comes with the battery
installed at the factory. If
you need to replace this
battery, use a coin to
unthread the battery cap

Before using your Turbo®

need to install the battery.

the transmitter should be
approximately 1/32”-
1/16” (1­2mm). Tighten
the magnet and
transmitter. Do
not over-tighten
the magnet
screw.
(See figure 5).

For wheels
with bladed spokes:

Use some isopropyl (rub­bing) alcohol or a mild
detergent to thoroughly
clean the spoke that you
plan to attach the magnet
to. Remove the backing
from the adhesive tape and
firmly press the magnet
onto spoke. The tape uses
a special pressure sensitive
adhesive. To ensure a
strong bond, please wait at
least 12 hours for the
adhesive to cure before rid­ing your bicycle.

Attach the appropriate
mount (26.0mm and

31.8mm sizes are includ­ed) to the handlebar using
the bracket screw provided.
Tighten so that the bracket
cannot rotate on the han-

dlebar. There are several
sizing straps provided to fit
different diameter bars.
(See figure 6). Slide the
computer rearward onto

the mount until it ‘snaps’
into place with an audible
click. To remove the com­puter, remove the cadence
wire (if connected) then
push it forward until it
releases from the mount.

To test for proper installa­tion of the magnet, trans­mitter and computer, acti­vate the computer by push­ing the ‘MODE’ (right side)
button. Pick up the front of
the bicycle and spin the
front wheel. The “wheel
option” indicator will flash.
If it does not flash, check
the sensor and magnet
alignment. Realign as nec­essary until the “wheel
option” indicator flashes
while spinning the wheel

from the transmitter hous­ing. Install the battery
(model 23A) with the posi­tive pole (+) facing
upward. Carefully thread
the battery cap back onto
the case with a coin.

INSTALLATION

MOUNTING THE
TURBO® PRO:

The Turbo® Pro wireless
transmitter can mount on
the right or the left side of
the fork blade. The right
side should be used on
large frames or when a
suspension fork is installed.
The optimal distance
between the computer and

the transmitter is 24 inches
(610mm). The distance
may need to be less than
24 inches (610mm) if
ambient temperatures are
below 40 °F (4 °C). To
reduce signal loss in colder
temperatures, the transmit­ter should be mounted as
close to the computer as
possible. (Maximum
mounting distance is 28
inches). Use the transmit­ter-mounting shim and tie­wraps provided to position
the sensor. Do not tighten
the tie-wraps until final
placement of
the magnet is
correct. (See
figure 4).
Wheel magnets
have been pro­vided for both
traditional
round spokes
and bladed (flat) aerody­namic spokes.

For wheels with round
spokes:

Attach the magnet to a
spoke across from the
transmitter with the magnet
screw. The clearance

MODE/SET rocker switch.
There are eight cycling
modes available: 1) Clock
Mode, 2) Distance Mode, 3)
Speed Mode, 4) Timer
Mode, 5) Cadence Mode, 6)
Countdown Mode, 7)
Altitude Mode and 8)
Temperature Mode. Within
each mode there is a side­mode that will allow you to
access additional informa­tion such as average and
maximum speeds. Use the
“SET” button, located on the
left-hand side the
MODE/SET rocker switch, to
cycle through the side­modes. Once you familiarize
yourself with the mode/side­mode operation you will find
it very easy to navigate. The
following flowchart outlines
the mode/side-mode
sequence. Once a particular
mode has been entered, its
values can be reset or
adjusted by pressing and
holding the “SET ” button for
three seconds.

1. Setting the
Display Language

Your Turbo® ® Pro can
display information on the

dot-matrix display area in
six different languages:
English (ENGL), German
(GER), French (FR), Italian
(ITA), Dutch (NED), and
Spanish (ESP). To select
your language push the
mode button repeatedly
until CLOCK is displayed
in the Dot-matrix Display
Area. Then, depress hold
the “MODE” button for
three seconds. The selected
language will be dis­played. Use the “MODE”
button to scroll through the
languages. When the
selected language is dis­played (default language is
English), press the “SET”
button once to confirm
your selection and exit dis­play language mode.

Mounting Cadence hard­ware- In order to use the
cadence option you must
install the cadence wire
provided with your Turbo®
Pro. Plug the wire into the
socket on the bottom of
your computer. Run the
cadence sensor wire along
the head tube, down tube
and along one of the chain
stays of your bicycle.
Secure it into place using
the provided tie-wraps.
(See figure 7). Next, attach
the cadence magnet to the

inside of your crank arm
directly across from the
sensor. Use a tie-wrap to
fasten the magnet to the
crank arm. (See figure 8).
Do not tighten the tie-wrap
until final placement of the
magnet is correct. The
clearance between the
magnet and the sensor
should be approximately
1/32”-1/16” (1-2mm).
(See figure 9). Tighten the
magnet and sensor.

OPERATION AND
PROGRAMMING

When your Turbo® Pro has
not detected any speed input
for 30 minutes, it will enter
sleep-mode in order to con­serve battery power. During
sleep mode only the digital
clock is displayed. You will
need to wake it up by push­ing the “Mode” or “Set” but-
ton once. In order to operate
your computer it must be
placed in various “modes”
(i.e. odometer mode, dis­tance mode). The computer
can be cycled through these
modes by pressing the
“MODE” button located on
the right-hand side the
