13. Set-up mode

Your VDO CYTEC C 15 features the following set-up procedures wheelsize 1 = WS1 wheelsize 2 = WS2 clock = CLK odometers = ODO1,ODO2

Trip Counter=TCNT set-up starts out of TRP in display set-up starts out of TRP in display set-up starts out of CLK in display set-up starts out of ODO1, ODO2 in display set up starts out of TCNT in display

No matter which set-up mode is used for your VDO CYTEC , the procedure is the same.

You can start the set-up mode for a certain display by pressing the MODE 1 button for 5 sec. With this MODE button you may also exit the set-up mode at any time.

Once the set-up mode is activated, MODE 1 and MODE 2 buttons are covered with following instructions:

MODE1

MODE2 changing from one enter display to the next enter display selection of figure to be entered, changing from KMH to MPH mode

14. Selecting the wheelsize

Your VDO CYTEC C 15 can work with two different wheelsizes (WS1 or WS2), i.e. one wheelsize for your road bike the other one for your mountain bike. When using the respective bike you can just switch to the proper wheelsize.

Wheelsize is only selectable if any of the following information is displayed: AVS-RID-STP-MAX

The currently active wheelsize is indicated in the display by WS 1 or WS 2. You can switch from wheelsize 1 (WS 1) to wheelsize 2 (WS 2) and vice-versa by pressing the MODE 1 button for 5 sec.

15. Entering your wheelsize

You may enter two different wheelsizes into your VDO CYTEC C 15, i.e. one wheelsize for your street bike and another one for your mountain bike.

Your VDO CYTEC identifies different wheelsizes as WS 1 = wheelsize 1 and WS 2 = wheelsize 2.

following defaults are entered wheelsize 1 = WS1 = 2155 mm wheelsize 2 = WS2 = 2000 mm

Watch out: Above defaults are automatically applied after a battery change.

After a battery change, the correct wheelsizes for your bikes have to be re-entered

How is the wheelsize precisely determined?

Place the front wheel of your bike with the valve at the bottom, mark this position with a line and push your bike ahead until exactly one rotation of the front wheel is completed. Draw another line where the valve now is. Take a ruler and measure the distance between marks 1 and 2 which reflects the wheelsize = wheel-circumference. The figure measured (inches or mm) is the wheelsize to be entered into your computer.

WS in mm / inch

Programming (setting up) your wheelsize

Step 1: Call TRP information in your display.

Step 2:

Step 3:

Press MODE 1 button for 5 sec. "WS1" is displayed along with an alternating flashing symbol for KMH and MPH.

By pressing the MODE 2 button you can choose whether you want MPH or KMH readout on your display.
