Technical specications C1DS C2DS C3DS C4DS 56 GB C1DS C2DS C3DS C4DS 1.0 VDO DIGITAL SYTEM Your VDO cycle computer operates on digitally coded, wireless transmission. Different from analogue radio transmission, data is digitally transmitted (data packages step-by-step). With your actual speed varying, the reading will change stepwise. Individual coding of the signals ensures that only data coming from your transmitter is processed. No interference with signals coming from transmitters other than yours. Very rarely, even digital transmission may be interfered by high-voltage power lines, mobile phone poles, remote controls (car doors openers, garage door openers). What happens when digital transmission is interfered with?

- speed display will read zero (0)

- trip distance stops counting

- ride timer stops counting The digital VDO transmitter features an internal memory, that stores up to 45 sec of data at a speed of 20 KMH (12,5 MPH). At a rare interference, no data is lost! The related data pack-

57 GB ages are sent after, once the interference is over. Following data is immediately updated when the re-send data is received :

trip distance riding time average speed maximum speed odometer Hence, your current data may change erratically after a interference = Update of your computer. After a battery change, a new coding is automatically generated in the transmit-

ter. The computer must learn this new coding. Therefore, you have to activate the manual transmitter search DIGI CONNECT RESET (3.1. Manual Transmitter Search DIGI CONNECT RESET) 58 GB 1.1 The VDO-USER-CARD Welcome to the Club. With the purchase of this product, you have become a member of the VDO-USER Club.

A. First install the battery in the digital transmitter Step 1. Place the battery into the transmitter housing, +pole face-up. Step 2. Make sure the battery is not edged over. Step 3. Check if the rubber washer is atly positioned on the battery door. Step 4. Place the battery door on the compartment, take a coin and twist it to the right until detent (approx. 1/3 turn). B. Install the battery in the computer immediatly after the installation of the battery in the transmitter. At the initial putting into operation, the computer is automatically trying to nd the transmitter. By this, the computer also learns the transmitters coding 62 GB IMPORTANT: On inserting the battery into the transmitter, the coding of the digital signals is automatically generated. The computer is only able to nd the coded signal at the initial putting into operation. After a battery change, a new coding is generated in the transmitter. In this case, the computer wont nd the coded signal and a manual transmitter search is required (DIGI CONNECT RESET) see chapter 3.1. After every start a green LED at the transmitter ashes for 20 sec. only The ashing LED indicates a working transmitter. TIP for battery change: VDO recommends an annual battery change. Buy a spare battery in due time to avoid unwanted loss of data. When changing the battery, all basic settings are reset to default values. Note your individual wheel sizes and accumulated mileages (odometer WS 1 / odometer WS 2) for both bikes before you remove the battery. Reprogram this data after the new battery has been installed. 63 C1DS C2DS C3DS C4DS GB 2.2 Mounting transmitter and magnet >>> P03 important mounting instructions:

a) maximum distance transmitter computer = 150 cm (59 in) b) distance transmitter - magnet: 3 to max 10 mm (up to 0.04 in) c) mount the transmitter on the fork leg, same side where you want the computer to be on the handlebar. (not applicable for stem mounting with optional stem holder). Step 1 Prex the transmitter on the fork leg with cable ties (do not tighten yet) Step 2 Put the magnet around a spoke, do not x Step 3 Direct the magnet to the marking on the transmitter at a distance of around 3 mm and shut the clip-mechanism Step 4 Align transmitter and magnet and tighten the transmitters cable ties. Clip off the cable tie ends not needed. 64 GB 2.3 Mounting the VDO any-size handlebar holder >>> P04 Step 1 Position the holder socket on the handlebar (stem optionally). Step 2 Feed the xing clamp through the slot below the holder socket, pass the clamp around the handlebar (stem optionally) and tighten it with a little screw driver.

sure the circumference of your wheels With an incorrect wheel size set, all related values like speed, trip distance, odometer etc. come out false. To make the use of your VDO computers possible on 2 bikes, i.e. Mountain Bike and Road Bike, you are able to set up 2 different wheel sizes. Measuring both wheel circumferences:

step 1 Place the front wheel valve perpendicular to the ground step 2 Mark this spot on the ground for example with chalk step 3 Turn the wheel forward for one full circle until the valve is step 4 Also mark this spot. step 5 Measure the distance between the two spots (markings) step 6 Set-up your wheel size in your VDO computer as perpendicular to the ground again This is your wheel size. described below. 75 GB If you have selected the Metric system (KM) you have to enter your wheel size/s in millimeters. If you have selected English system (MI) you have to enter your wheel size/s in inches. TIP: Write down your wheel sizes on your VDO-User-Card for easy reference. The values listed in the chart >>>P08 are approximate. Depending on the tire brand, it is possible that these numbers deviate from your real tire circumference since height and tread pattern are likely to be different. Setting the wheel sizes :
