• WARNING: Failure to pay attention to the road, trail, traffi c or your surroundings could result
in an accident, with risk of serious injury, paralysis or death. You must focus on riding, not your
computer. Learn computer operations, and do all possible computer operations when not riding.
For any operations you choose to perform while riding, choose a time and place where this
distraction has less risk.
• CAUTION: Mount the Cyclecomputer according to the directions in this instruction manual.
• CAUTION: Avoid direct impact to the Cyclecomputer unit.
• CAUTION: Do not submerge the Cyclecomputer unit.
• CAUTION: Avoid using the Cyclecomputer unit in or near strong electromagnetic fi elds such as
high-voltage power lines or other transmitters.
• CAUTION: Do not disassemble the unit.
• CAUTION: Make sure the magnet and the transmitter are well aligned and check them regularly.
• CAUTION: PRO SX4 Cyclecomputers are intended for use on bicycles only and should not be
used on any motorized vehicle.
• CAUTION: Change the battery prior to failure to avoid data loss.
• CAUTION: Clean the unit with a mild detergent and a soft dry cloth. Never use any kind of
solvent or alcohol.
COMPONENTS OF THE CYCLECOMPUTER (Fig. 1)

REPLACING THE BATTERY
PRO SX4 Cyclecomputers are powered by a CR2032 3v Lithium Battery. Under normal conditions, this battery
should last approximately one year.
REPLACING THE COMPUTER BATTERY
1. Computer: Using a (-) screw driver to lever the battery door comes up. (Fig 2)
Wireless speed transmitter: Using a coin, turn the battery door counter clockwise until the door comes
free. (Fig 3)
2. Take care not to damage the O-ring seal for the battery compartment and remove the old battery from
the battery door.
3. Place a new battery in the transmitter positive (+) side toward the battery door.
4. Close the battery door.
5. If the O-ring has been damaged, replace it before reinstalling the battery door.
CAUTION : 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.

INSTALLING THE WIRELESS FORK TRANSMITTER (4a)
The PRO SX4 receives 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 towards wheel side. The sensor should be mounted as high on the fork blade
as possible. The range of the transmitter
2. Attach the spoke magnet to a spoke on the same side of the wheel as the sensor.
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.
MOUNTING THE HANDLEBAR/STEM BRACKET (4b)
1. Pick the correct bracket.
2. Place the Cycle computer unit into the mounting bracket.
3. Place the mounting bracket in the desired position on handle bars or stem.
4. Thread the zip-ties provided through the holes on one side of the mounting sleeve and around the handlebar or
stem.
KEYS & THEIR FUNCTIONS (Fig. 5)

DETERMINING YOUR WHEEL SIZE (7a)
Option 1: Choose the applicable wheel circumference from the chart.
MEASURING WHEEL SIZE USING ROLLOUT METHOD (7b)
Option 2: 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.
3. Measure the distance from the first mark to the second in millimeters and enter the resulting number into your
computer.
