CYCLE COMPUTER OWNER'S MANUAL
ENGLISH
INTRODUCTION
Congratulations on your purchase of the new Vetta V-30 cycle computer. The V-30 is designed to be the
simplest, smallest computer that you can own. The unique Vetta buttonless design allows easy
programming and operation. The Auto Scan feature of the V-30 keeps you updated on current speed,
trip distance, and total distance automatically every three seconds. No buttons to push!
COMPONENT ILLUSTRATIONS
Head Unit Sensor Bracket Battery Magnet
SPEEDOMETER (SPD) (Mi/hr or Km/hr)
Tells you your current speed on the upper line of the display screen at all times.
CUMULATIVE ODOMETER (ODO)
Tells you your cumulative distance until the unit is reset by removing and
reinstalling the battery, or until the unit passes 9999.9 mi. or km.
TRIP ODOMETER (DST)
Tells you the distance for your current ride from 0 to 999.99 mi. or km. Auto-
matically resets after 999.99 mi. or km. or after 6 hours of continuous
non-use. Trip Odometer will commence automatically when the bicycle wheel
begins to rotate.

AUTO SCAN
The Vetta V-30 computer is programmed to automatically scan between the trip distance and total
distance readings on the bottom line of the dual display. Current speed is displayed at all times in large
digits on the top line of the display.
AUTO POWER SAVING MODE (AUTO START-STOP)
When you stop using the computer for 10 minutes (no signal input for 10 continuous minutes), the
display will disappear and the unit will automatically go into power saving mode. When the unit begins to
receive a signal again (wheel in motion) it will automatically switch from power saving mode and
display all functions.
AUTO DATA CLEARING
When the computer is not used for 6 hours, all of the current trip distance data stored in memory will be
erased. Wheel circumference and cumulative odometer data will be retained. When the computer is used
next, speed and trip distance will commence from zero.
FEATURE LIST
BATTERY INSTALLATION
The V-30 uses a common LR44 1.5v button cell 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.
STEP 1
Remove the battery cover from the bottom of the computer by turning the
battery cap counterclockwise with a coin.
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.
STEP 3
Screw the battery cap firmly into place. Make sure that the rubber o-ring seal does
not get pinched or distorted in this operation as this may compromise the
waterproofing of the unit.

WARNINGS AND CAUTIONS
PROGRAMMING THE COMPUTER HEAD
Vetta encourages you to ride safely. Wear a helmet every time you ride, use front and rear lights
at night, and always keep your eyes on the road ahead of you.
Vetta cycle computers are sophisticated electronic instruments. Vetta recommends that this
product be installed only by a qualified bicycle retailer. Failure to read these instructions and improper
installation of this device may void the warranty. If you are in doubt about any aspect of the installation or
operation of this product, consult your local bicycle retailer for clarification.
Now that you are familiar with the functions and features of your Vetta V-30 cycle computer, you are ready to
begin programming the unit specifically for your bike. Take a few minutes to familiarize yourself with the unit
and its operation before you proceed to program the unit.
IMPORTANT: When you program the V-30 unit, it will automatically advance through the programming
functions as each number or increment is selected. To advance the numbers in a function setting, put the
magnet directly on the sensor. This will advance the digits or units you are trying to “set”. To select the
number that you desire, remove the magnet from the sensor while that number or unit is displayed.
CAUTION
CAUTION
SETTING MILES/HOUR OR KILOMETERS/HOUR
The Vetta V-30 computer is capable of being programmed to display readouts in
either miles or kilometers.
STEP 1
After installing the battery, the computer will momentarily display a diagnostic
test pattern screen and then advance quickly to the miles or kilometers setting
mode indicated by a flashing “Km/hr”icon.
STEP 2
Insert the head unit into the handlebar mounting bracket and place the
magnet directly on the wheel sensor. Miles and kilometers icons will be
displayed alternately on the screen.
STEP 3
When the distance unit that you would like to select is displayed, remove the magnet from the wheel sensor to
set your selection. The computer will then automatically advance to the wheel size setting mode.
NOTE: If you make a selection error while programming your computer or would like to change any of your
previously programmed settings, you must remove and then reinstall the battery and start over. All settings will
return to their original default values. You can then reprogram the computer.
DETERMINING YOUR CORRECT 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 many 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 wheel
circumference 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, simply 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). The result is your wheel circumference calculated in
millimeters.
STEP 3
Enter this resulting number into the computer (see next instructions).
PRESET VALUE
The V-30 has a factory preset wheel size value of 2155 (700 x 32c).
