Mounting the system
1. Mounting the handlebar holder
The handlebar holder fits handlebars of any diameter. Before mounting the system, decide if you will be using your left or right hand
to operate the computer and then mount the handlebar holder on the respective side. Position the handlebar holder, insert the strap
and adjust it by tightening the screw.
Warning: Before tightening the handlebar holder, make sure to adjust the position of the computer head (inclination) when the LCD-
display is best visible for you. Only when you find the best position tighten the screw.

2. Mounting the speed transmitter
The sensor should be mounted on the same
side of the fork as the holder is on the
handlebar.
Watch out: Do not tighten the cable ties
yet! Accurately position the spoke magnet
and the sensor first, then tighten the cable
ties.
3. Mounting the spoke magnet
Distance between magnet and
sensor should be approx. 1-5 mm.

In case this distance is not
achievable in the current positioning,
slide the sensor and the magnet on
the fork or spoke accordingly.
4. Twist-Click mounting of computer onto holder
The Twist-Click mounting has been exclusively developed for the new line of VDO
CYTEC computers. The computerhead is put onto the handlebar and by a right turn
of the computerhead (TWIST) fixed to the holder (CLICK). It is just as easy to remove
the computerhead from the handlebar holder. Slightly push the computerhead down,
twist it to the left, remove computerhead from handlebar holder.

11. Entering your wheelsize
Your VDO CYTEC identifies wheelsize as WS = wheelsize.
following default is entered
wheelsize = WS = 2155 mm
Watch out: Above default is automatically applied after a battery change.
After a battery change, the correct wheelsize for your bike has 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
10. Set-up mode
Your VDO CYTEC C 08 features the following set-up procedures
wheelsize = WS set-up starts out of TRP in display
clock = CLK set-up starts out of CLK 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:
