D GB F I I F4.6 Transmitter pairing5.2 Setting and measuring the wheel sizeGBDThe speed and cadence signals (Option: Item no.7702) will be transmitted digitally and encoded toyour computer. This technology is less prone toproblems than analogue transmission. This way,when riding in a group there are no data overlaps(cross talk). So that the computer acquires thedigital encodings from the transmitter, a pairingmust be made:ATTENTION: The time window for pairing is5 minutes. If you do not start cycling duringthese 5 minutes, no pairing takes place.Speed and cadence are not displayed.The pairing then has to be repeated:B Place the computer back into the handlebarholder ORB press the buttons C + M together.You must set the wheel size (wheel roll circumference)of your bike so that your VDO computercan measure correctly. There are 2 ways ofdoing this:5.2.1 Setting using tyre tablestep 1 Place the computer into the handlebarholder. The display for the speed and the cadencenow flashes. The flashing shows that the computeris looking for its transmitter.step 2 Spin the front wheel or simply set off andthe computer acquires the digital encodings.When the computer has found the transmittersand has acquired the encodings (pairing), thespeed and cadence are shown on the display.5. Basic settings5.1 Setting the languageUsing the buttons, go toSETTINGS/SELECT.Confirm with M.You are now in setting mode(pressing C for 3 seconds getsyou back to function mode).to LANGUAGE SELECT.Confirm with M.to LANGUAGE ENGLISH.Confirm with M.ENGLISH SELECT OK? Confirm with M.LANGUAGE SELECT DONE. The computer automaticallyreturns to the start menu SETTINGS/SELECT.The common types of tyres are listed in the tyretable. If your tyre type is not listed, we recommendentering the wheel size manually.The values given in the table are approximatevalues. These values differ according to brand, tyreheight and tyre profile. This can consequently alsolead to discrepancies in the distance measuredand the speed shown.mm-value inch-value16 x 1,75 1272 50,120 x 1,75 1590 62,624 x 1 ⅜ 1948 76,724 x 1,75 1907 75,126 x 1 1973 77,726 x 1,5 2026 79,826 x 1,6 2051 80,726 x 1,75 2070 81,526 x 1,9 2089 82,226 x 2,00 2114 83,226 x 2,125 2133 84,026 x 1 ⅜ 2105 82,926 x ¾ 1954 76,927 x 1 ¼ 2199 86,628 x 1,5 2224 87,628 x 1,75 2268 89,328 x 1 ½ 2265 89,228 x 1 ⅜ 2205 86,830-622 2149 84,632-622 2174 85,637-622 2205 86,840-622 2224 87,640 X3DWVDO CYCLECOMPUTINGwww.vdocyclecomputing.com X3DW 41
