REPLACING THE BATTERY
PRO Scio Cyclecomputers are powered by a CR2032 3v Lithium Battery. Under normal condi-
tions, this battery should last approximately one year.
REPLACING THE COMPUTER BATTERY
Using a coin, turn the battery door counter clockwise until the
door comes free.
2. Take care not to damage the O-ring seal for the battery com-
partment and carefully remove the old battery.
3. Place a new battery in the battery compartment with the posi-
tive (+) side toward the battery door. Be extremely careful not
to bend the battery contact when inserting a new battery.
4. Place the battery door over the opening and tighten it down by using a coin and turn-
ing in a clockwise direction.
5. If the O-ring has been damaged, replace it before reinstalling the battery door.
#!54)/.Extreme care should be taken when replacing the battery to ensure the unit
remains fully water resistant. Failure to properly replace the battery and correctly seal the
unit may cause the unit to become damaged and may void the warranty.

2. Take care not to damage the O-ring seal for the battery
compartment and carefully remove the old battery.
3. Place a new battery in the transmitter positive (+) side toward
the battery door.
4. Place the battery door over the opening and tighten it down
by using a coin and turning in a clockwise direction.
5. If the O-ring has been damaged, replace it before reinstalling

The PRO Scio 4.1 features a wireless heart rate transmitter, powered by a CR2032 3v
Lithium battery. Under normal conditions you can expect to get approximately 700-800
hours of heart rate transmitter use with a fresh battery.
Using a coin, turn the battery door counter clockwise until the door
comes free of the watch.
2. Take care not to damage the O-ring seal for the battery compartment
and carefully remove the old battery.
3. Place a new battery in the battery compartment with the positive (+)
side toward the battery door.
4. Place the battery door over the opening and tighten it down by using
a coin and turning in a clockwise direction.
5. If the O-ring has been damaged, replace it before reinstalling the bat-
tery door. Most jewelers and watch shops should have replacement
O-ring seals.
./4% Extreme care should be taken when replacing the battery to ensure
the unit remains fully water resistant. Failure to properly replace the bat-
tery and correctly seal the unit may cause the unit to become damaged and

To ensure a proper heart rate display, the chest transmitter
must be moistened and properly adjusted. Wet the elec-
trodes (located to the right and left of the main transmitter
case) with saliva or ECG conductive gel. Do not use water,
moisturizing creams or suntan oil, as these are insulators
and may interfere with the heart rate signal. Snap the
plastic tabs at the end of the elastic belt into the holes
at the end of the transmitter, and adjust the strap so that
the transmitter fits tightly below the pectoral muscles, as
shown in the drawing.
./4%Users with significant chest hair may have a problem
obtaining contact between the transmitter electrodes and their skin, resulting in poor
performance. It may be necessary for these individuals to shave the area of their chest
beneath the transmitter.
./4% In dry and cold climates it may take a few minutes of use for the electrodes to soften,
and a layer of perspiration to form between the contact and the skin for good performance.
Moistening the electrodes with saliva or ECG conductive gel can speed up this process.

INSTALLING THE CYCLECOMPUTER ON YOUR BIKE -
PRO SCIO 3.3
MOUNTING THE WIRED CADENCE SENSOR
On the PRO Scio 3.3, speed is picked up wirelessly from the front wheel
and cadence is picked up via a wired connection from the crank arm.
The wired cadence sensor is best installed starting with the cadence
sensor unit and then working up toward the handlebar or stem bracket.
1. Attach the cadence sensor to the LEFT chain stay near where the
crank/pedal pass the stay using the zip-ties provided. Do not fully
tighten zip-ties.
./4%The wires exiting the sensor should be pointing toward the front
of the bike.
Attach the cadence magnet to the back side of the LEFT crank arm
using the zip-tie provided.
Align the cadence sensor and magnet and rotate the sensor so the
magnet passes within 1-3mm.

MOUNTING THE WIRED CADENCE SENSOR
(continued)
4. Route the sensor wire forward and under the bottom bracket and
along the bottom of the down tube securing it occasionally with
tape. Once you are near the head tube the sensor wire should be
wrapped around the front or rear derailleur cable housing and the
around the front brake cable housing.
Wrap any excess wire around the front brake cable housing. Use
electrical tape to secure the cable in place if necessary. When you
are done you should have just enough wire left to connect to the
receiver unit’s mounting point.
#!54)/.Make sure you leave enough slack in the sensor wire so the
handle bars can turn fully from side to side.

INSTALLING THE CYCLOCOMPUTER ON YOUR BIKE
INSTALLING THE WIRELESS FORK TRANSMITTER
The PRO Scio 3.3, 3.5 and 4.1 receive speed and distance from a wireless transmitter
mounted to the front fork.
1. Attach the wireless front wheel sensor and rubber mounting
pad to the front of the left fork blade using the zip-ties
provided so the battery cap is pointing downward. Snug up
the zip-ties but do not fully tighten them. The sensor should
be mounted as high on the fork blade as possible. The range
of the transmitter is approximately 18in (46cm). Mounting
it high on the fork will assure good signal reception. Other
mounting locations may work, but we feel this is the best
location for most applications.
2. Attach the spoke magnet to a spoke on the same side of
the wheel as the sensor. Tighten the attachment screw just
enough to hold the magnet in place but loose enough so that
it is still movable.

3. Adjust the position of the sensor and magnet so they are in
proper alignment as shown. The magnet should pass by the
sensor adjacent to the molded plastic line at a distance of
1-3mm.
4. Once everything is in alignment, fully tighten the spoke
magnet in place and tighten the zip-ties holding the sensor to
the fork.

MOUNTING THE HANDLEBAR/STEM BRACKET
Place the Cyclecomputer unit into the mounting bracket and turn
clockwise until the unit snaps into place.
./4%When mounting the unit on the stem, you must first remove the
4 screws on the back of the mounting bracket and rotate it 90 degees.
Replace the screws - do not overtighten. The unit is now properly aligned
for mounting on the stem.
2. Place the mounting bracket in the desired position on handle bars
or stem.
3. Thread the zip-ties provided through the holes on one side of the
mounting sleeve and around the handlebar or stem. Once the unit
is positioned correctly, secure the zip-ties and trim off the excess
ends.

MEASURING WHEEL SIZE
DETERMINING YOUR WHEEL SIZE
PRO Scio Computers use the rolling circumference of your wheel and tire combination to
determine speed and distance. The more accurate this setting, the more accurate your ride
information will be. However, variations of less than 30mm from the actual circumference
will have very little impact on the overall accuracy of the unit.
For easy setup, PRO Scio computers come with 14 pre-programmed wheel/tire sizes. Simply
select the size of your tire as you scroll through the list in the programming sequence.
If your wheel/tire size is not one of the sizes in the accompanying chart, or if you desire abso-
lute accuracy, you may enter an exact wheel circumference into the system. Use the method
on the following page for measuring the circumference of your wheel/tire combination.

MEASURING WHEEL SIZE
MEASURING WHEEL SIZE USING ROLLOUT METHOD
The roll-out method is the most accurate method for determining the circumference of your
wheel/tire combination.
1. On a flat open surface make a mark on your tire and the floor exactly where they
meet.
2. Roll your bike forward one full revolution of the front wheel and mark the point on the
floor where the revolution is complete. For maximum accuracy be sitting on the bike
while someone rolls you and the bike forward.
3. Measure the distance from the first mark to the second in millimeters and enter the
resulting number into your computer.
