BATTERY INSTALLATION
The head of the C-500 uses a common 3032 3v lithium button cell battery, and
the transmitter uses a common 23A 12v battery. Replacement batteries are
available at most camera shops and from your Vetta retailer. Under normal usage
a battery should last approximately one year.
NOTE: Most problems that occur
with cycle computers are caused by dead or weak batteries. If you are having
problems with your computer's operation, check and replace the battery first.
INSTALLATION OF HEAD UNIT BATTERY
STEP 1
Remove the battery cover from the bottom of the computer using a small flat
blade screwdriver.
STEP 2
Install the battery into the battery compartment with the positive (+) side of the
battery facing the compartment door. Be careful when you are installing the
battery not to bend any of the battery contacts.
3032 3v Lithium Battery
AUTO CLEAR BUTTON
Press for total reset of unit.
All stored data will be erased.
!CAUTION
!
STEP 3
Press the battery cap firmly into place making sure that the rubber o-ring seal
does not get pinched or distorted as this will compromise the waterproofing of
the unit.
INSTALLATION OF TRANSMITTER BATTERY
The transmitter should come from the factory with the 23A 12v battery installed.
STEP 1
To replace the battery, first remove the battery cap on the top of the transmitter
with a coin. Remove the old battery and dispose of properly.
NOTE: Check
the inside of the transmitter for corrosion. If corrosion is visible replace the
transmitter with a new unit.
STEP 2
Install a new battery in the transmitter battery compartment with the positive
(+) side facing the opening and reinstall the battery cap.
CAUTION Make sure that the battery cap is tight to prevent moisture from
entering the transmitter unit. An improperly installed battery can damage the
23A 12v Battery

SETTING MILES/HOUR OR KILOMETERS/HOUR

DETERMINING YOUR PROPER WHEEL SIZE
Vetta cycle computers are programmed using the circumference of the wheel measured in millimeters. Note
that while your computer can be programmed to +/- 1mm for total accuracy, discrepancies of as much as
50mm or more will not have a significant effect on the accuracy of the unit for most normal rides.
The following chart lists the programming sizes for some of the most popular wheel sizes currently in use.
These numbers are estimations and may vary slightly from the size of your actual wheel depending on the
manufacturer of the tire that you are using.

WHEEL SIZE CALCULATION
If the wheel size of your bike is not listed in the chart, follow these simple steps to calculate the calibration
number for your bike.
STEP 1
Measure the distance from the center of the front axle to the ground in millimeters. If you are measuring in
inches, multiply the number of inches by 25.4 to get millimeters. If you want total accuracy make this
measurement while you are sitting on the bike.
STEP 2
Multiply the above number by 6.2832 (2π).
STEP 3
Enter the resulting number into the computer.
PRESET VALUE
The C-500 has a factory preset wheel size value of 2074 (700 x 20c).

PROGRAMMING YOUR WHEEL SIZE
STEP 1
Once you select miles ( ) or kilometers ( ) and press the lower key
(A), the C-500 will automatically advance into the wheel size setting mode. (See
SETTING MILES/HOUR OR KILOMETERS/HOUR)
STEP 2
The right hand digit (4) will begin flashing. Use the upper key (B) to advance to the
number that you want.
NOTE: Hold the upper key (B) to fast advance through the digits.
STEP 3
Press the lower key (A) to set the number and advance to the next flashing digit (7).
STEP 4
Repeat this sequence until all digits are at the appropriate settings.
STEP 5
Press the lower key (A) one final time to enter the wheel size setting into memory
and advance the unit back to the /screen.
The Vetta C-500 cycle computer is equipped with a digital clock that displays time
in a 12 hour format.
STEP 1
With the display in the mode, press the lower key (A) for 2 seconds.
STEP 2
The screen will clear and the hour digits will begin to flash. Advance the digits
using the upper key (B).
NOTE: Hold this key to fast advance through the digits.
STEP 3
When you have selected the correct digit, press the lower key (A) to enter the digit
and advance to set the minutes using the same procedure as above.
STEP 4
Press the lower key (A) to set the minutes and return to the screen.
SETTING THE CLOCK

MAGNET, SENSOR AND BRACKET INSTALLATION
Because your C-500 is wireless, the mounting of the unit is simple and straight
forward. Begin by mounting the head unit and bracket to the handlebars.
STEP 1
Clamp the bracket around the handlebars and tighten in place. All Vetta cycle
computer brackets are designed to work with 26.0 - 26.4mm standard
diameter road handlebars. Shims are provide to fit smaller 25.4mm mountain
and road bars. Make sure not to over tighten the bracket as this may result in
breakage. The bracket only needs to be tightened enough to keep it from
spinning on the handlebar during normal riding.
STEP 2
Loosely, mount the C-500 transmitter to the leading edge of your left fork
blade using the flat rubber block and the 2 zip-ties provided. The arrow
printed on the side of the transmitter should be facing the spokes and pointing
toward the bracket on the handlebars.
Installation Diagram
!
On some bikes it may be necessary to use the angled spacer that is provided
in place of the flat spacer, in order to get the transmitter to line up correctly
with the head unit.
STEP 3
Attach the spoke magnet to the wheel, and adjust the alignment of the magnet
and transmitter so that the magnet passes the transmitter within 1-2mm of
the small line molded into the lower part of the transmitter and the word
MAGNET printed on the side of the transmitter.
CAUTION The C-500 uses an offset bracket design. It is designed to be
supported by the handlebar stem when it is installed. It is NOT necessarily
designed to fit directly over the center of the handlebar stem. Especially if this
causes the bracket to be bent or deformed. Install the C-500 bracket so that
the stem provides support and a firm platform for the computer.

HEAD UNIT INSTALLATION
!
The heads of all Vetta computers are designed to lock into their brackets.
When installing your computer head into the bracket you should hear an
audible “SNAP” indicating that the unit is locked firmly in place. The head of
the C-500 will slide into the bracket from the back to the front, this feature
keeps the unit from inadvertently being pushed out of the bracket during
normal use.
CAUTION Because the C-500 is a wireless cycle computer, it will operate
without being fully secured in the bracket. BE SURE THAT THE HEAD IS
FULLY LOCKED IN PLACE IN THE BRACKET BEFORE USING THE UNIT.
Once you have finished with the installation procedure, you are ready to test the unit to make sure that it works.
STEP 1
Advance the computer to the speedometer mode.
STEP 2
Pick up the front of the bicycle and spin the front wheel. The computer should register speed within 1-2 seconds.
If you do not get a speed reading, check to be sure that the magnet and sensor alignment is correct and that
the space between the magnet and sensor is 1-2mm or less. If this does not solve the problem, call the Vetta
customer service hotline at 1.800.GO.VETTA.
