seconds. Note: Whenever TT is activated, the stopwatch icon appears; otherwise it does not appear. The TT Timer must be active in order for the RT Timer to accumulate Ride Time and for the computer to calculate current ride data. CAUTION: If RT and TT timers are not 0:00:00 and you have stopped them manually, then they MUST be restarted manually by pressing Button #3 in the RT/TT mode.
SPEED* CADENCE* When installed, the Cadence kit measures and displays pedal Cadence in Revolutions Per Minute (RPM). The SPD/CAD screen function letters appear ONLY when the Cadence hardware is installed and a Cadence signal received by the head unit. After a current ride data reset, (Button #3 for 2 seconds with the timers off ) the function letters will disappear, but they will come back on with the next...
TOT ALT TOTAL ALTITUDE MAXIMUM ALTITUDE MAX ALT Total Altitude displays the cumulative altitude gain achieved for any given ride in feet or meters on the upper line. The Maximum Altitude or highest elevation attained during a ride is displayed on the lower line. Note: TOT ALT does not include descents.
SPEED TEMPERATURE Current Temperature is displayed in the lower screen digits and updated once per minute. The thermometer icon illuminates when the Temperature display is active, and the right digit displays the scale selected in degrees Celsius "C" or degrees Fahrenheit "F". Below zero readings are indicated by a minus sign (-).
Stopwatch and ID functions; press Button #3 again to stop functions and freeze data for review. Reset Stopwatch, Intermediate Distance and Intermediate Altitude to zero by pressing Button #3 for 2 seconds. STOPWATCH INTERMEDIATE ALTITUDE Like the Intermediate Distance function described above, Intermediate Altitude tracks an intermediate climb within a longer ride and displays it on the lower line.
DUAL BIKE MEMORY The V100A can be calibrated for two bicycles. It will store separate Wheel Size, Service Timer, Odometer and Altitude settings, as well as different formats selected for Time, Temperature, Speed and Distance. The current bike number (I or II) is always displayed in the lower right corner of the screen.
MAXIMUM CADENCE* MAX CAD When the Cadence mounting kit is installed, the V100A displays both Average and Maximum Cadence in a secondary screen. Press and hold Button #1 in the SPD/CAD screen mode for 2 seconds. The Average and Maximum Cadence functions appear on the upper and lower lines respectively.
(See SETUP section below for details.) LOW BATTERY ALERT The V100A Service Timer icon has been programmed to signal low battery power in the head unit. When the battery runs low and needs to be replaced, the Service Timer icon ( ) will illuminate and stay "on"...
FREEZE FRAME MEMORY Freezes ride data from 5 primary screens SPD/DST for review at any point during a race or training ride. To activate Freeze Frame, press and hold Button #2 for 2 seconds SPD/DST in any primary screen mode. The screen will flash to indicate it has been frozen.
AUTO START If the RT/TT ride timers read zero (0:00:00), the Vetta V100A computer automatically starts as soon as it receives input from the wheel. The RT and TT timers are activated and other ride data begins to accumulate (SPD, DST, AVG & MAX SPD, CAD*, AVG &...
RIDE DATA RESET To reset current ride, Freeze Frame and Altitude data to zero (DST, RT, TT, AVG & MAX SPD, AVG & MAX CAD*, TOT & MAX ALT, MAX % & MAX % (-), MAX & MIN TMP, STP, ID and IA), make sure the timers (RT/TT) are turned OFF and press Button #3 for 2 seconds in any primary screen mode except STP/ID or STP/IA.
BATTERY INSTALLATION HEAD UNIT The V100A head unit uses a CR2032 3V lithium button cell battery. IMPORTANT: Most cycle computer problems are caused by weak or dead batteries. See the Troubleshooting section near the end of this manual for details.
WL WIRELESS SPEED TRANSMITTER The V100A WL wireless speed transmitter (signal from the wheel) uses an A23 12V battery. Remove cap, install battery with positive (+) side up, replace battery cap. CAUTION: Make sure the transmitter battery cap is properly installed to insure good signal transmission.
SETUP MODE & PROGRAMMING INTRODUCTION After battery installation, the master screen will appear briefly and the computer will automatically go into the Initial Setup program mode. Note: To enter Setup when in the Normal Operating Mode (NOM), go to the SPD/DST screen mode and press Buttons #1 and #2 simultaneously for 2 seconds with the RT/TT timers off.

SETUP: ALTIMETER MEMORY 1 & 2 After Altimeter "ON" is selected, the computer advances to Altimeter Memory 1 Setup. This is the first of two Altimeter Memory settings in which the user can enter known elevation values to serve as quick, pre-ride Altimeter calibrations.
Page 28
When programming Altimeter Memory 1, the number "1" appears just below the elevation figures (see illustration). When all the values for Altimeter Memory #1 have been set, press Button #1 to select it and advance to Altimeter Memory 2 setting. In this screen the number "2"...

SETUP: SERVICE TIMER The Service Timers, one for each bike, may be programmed with a select number of ride time hours as the interval for servicing the bicycle or any component on it, such as a front or rear shock. Accumulated Ride Time is displayed on the upper line and the Service Time interval is set and displayed on the lower line.
Page 32
• To stop the Service Timer icon from flashing: A) Reset the accumulated Ride Time hours (upper line) to zero "0" through the NOM Setup sequence. The Service Timer interval may also be reprogrammed at this point. B) Change TT setting to a number larger than accumulated RT.

SETUP: ODOMETER Bike I and Bike II have separate, programmable odometers. On a new computer the Odometer screen should read "00000" for both. To confirm this initial zero setting, simply press Button #1 successively to select each flashing digit and advance to System Check.
Page 35
To change any values or correct any unit errors made during Initial Setup, you must re-enter the Setup program in NOM by pressing Buttons #1 and #2 simultaneously for 2 seconds in the SPD/DST screen mode with the RT/TT timers deactivated. Note: System Check is activated in two ways: A) Automatically at the end of either Initial or NOM Setup and B) By pressing Button #3 at any time during NOM Setup.
PRE-RIDE ALTIMETER CALIBRATION SETUP INTRODUCTION Before any new ride, the V100A Altimeter must be recalibrated so that it "knows" the correct starting elevation. Because elevation is calculated via barometric pressure, changes in barometric pressure detected by the sensor change the elevation displayed on the ALT/% screen.
Page 37
PRE-RIDE ALTIMETER CALIBRATION To calibrate the Altimeter, access the Pre-Ride Altimeter Calibration Setup program in NOM from the ALT/% screen. Press both Buttons #1 and #2 simultaneously for 2 seconds to enter the Setup screens for Altimeter Calibration. A) The first screen shows the Memory 1 Altimeter setting.
Page 38
BAROMETRIC CALIBRATION The V100A Altimeter may also be calibrated by entering the current, local, barometric pressure at sea level either in Inches of Mercury (inHg) or in Millibars (mbar). To access the barometric entry screens, press Button #2 to bypass the Manual Altimeter Elevation input screen (See point C above).

You should hear an audible “CLICK” when the head unit has been properly locked into position. This indicates proper alignment between the computer head pins and the active mount contacts.
If these checks do not solve the problem, talk to an Authorized Vetta Retailer or connect to www.vetta.com. IMPORTANT: Following the installation tests above, make sure that the spoke magnet locking screw and all zip ties are properly tightened.
TROUBLESHOOTING PROBLEM/ITEMS TO CHECK/SOLUTION • Current speed reading is erratic or does not appear. Check the alignment of the spoke magnet and sensor, and the distance between the two components. Realign the magnet and sensor with the spacer. Check to be sure RT and TT are activated.
