To toggle between Bike I and Bike II settings, press Button #2. With Bike "I" icon flashing, press Button #1 to select it and advance to the next Setup screen. Note: When programming a second bike in Initial Setup, scroll to "II", select it, and advance as instructed above.
SETUP: ALTIMETER ON/OFF This Setup screen allows you to turn the Altimeter function "ON" or "OFF" as you choose. The default setting for the Altimeter is "ON". Press Button #1 to select Altimeter "ON" and advance to the next screen. Or, if you don't want to activate the Altimeter function, press Button #2 to toggle to the "OFF" setting and press Button #1 to select it and advance.
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. When a rider frequently starts his or her ride from home or another location with a known elevation, the Altimeter Memory feature enables them to recalibrate the computer quickly and easily at the start of a ride.
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" appears on the lower display line. To program a second elevation into Altitude Memory, proceed as described above for Memory 1.
WHEEL SIZE CALCULATION The circumference of the wheel is measured and entered in millimeters. Bike I and II wheel sizes are set independently, and both default to 2074mm (700c x 20 or 26 x 2.0). The following chart lists the circumference measurements for the most common wheel sizes. To use this chart, find your tire size and record the corresponding circumference measurement.
SETUP: WHEEL CIRCUMFERENCE After Altimeter Memory 1 & 2 values have been selected and the display advances to the Wheel Size Setup screen, the letters "circ" appear on the lower level and the default numbers 2074 appear on the upper level with the right digit "4" flashing. Step 1: To enter a specific wheel size, press Button #2 to advance the flashing digit to the desired number. Step 2: When the correct number is reached, select it by pressing Button #1.
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. In the Service Timer Interval Setup mode, the hour digits appear on the lower level with the right hand digit flashing.
• 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. C) Set TT to zero "0000" (disable the Service Timer). • The Service Timer option can be disabled in Initial or NOM Setup mode by entering and selecting a value of zero "0000" hours as the service time interval (lower line).
SETUP: TEMPERATURE UNITS A highlighted thermometer icon indicates that the computer is in the Temperature Setup screen mode. The flashing "F" indicates Fahrenheit. To choose temperature readings that are displayed in the Fahrenheit scale, press Button #1 to select it and advance. To select the Celsius scale, press Button #2 to scroll to a flashing "C". Then press Button #1 to select and advance. SETUP: CLOCK The V100A clock displays time in either a 12 or 24 hour format.
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. To reenter mileage achieved after a battery change, follow these steps: Step 1: When the far right digit begins to flash, press Button #2 to scroll to the desired number.
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. To exit System Check manually in NOM Setup, press Button #3 to return to the SPD/DST primary screen mode.
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. Barometric pressure falls as elevation increases and rises as elevation decreases.
PRE-RIDE ALTIMETER CALIBRATION A B C 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. Press Button #1 to select that altitude setting, or B) Press Button #2 to advance to the Altimeter Memory 2 setting and press Button #1 to select.
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). The letters "inHg" will then appear and start to flash.
PERCENT GRADE VETTA uses a barometric sensor to gauge the (noise) changes in the air pressure which does not update constantly; this is why sometimes you may get varying readings due to weather changes, fast ascents and descents or not enough change in altitude i.e. small rolling hills. These are some of the other guidelines you can use to improve the accuracy of readings.
V100A Cycle Computer will output and update Percent Grade (%) of uphill or downhill whenB the vertical displacement is greater A than 3 meters.
