Seimens VDO Digital Tachograph
All Digital Tachograph Units have a minimum number of steps that have to be completed prior to driving:
Step 1 - Insert Card
Slide the card into Card Slot 1.
The Card should be entered:
CHIP UP, CHIP FIRST
Step 2 - Answering on Screen Questions
The screen should now read "Busy Processing"
Next, will appear Cardholders Name e.g. "Laurie Driver"
Following on from this will be the question "M Entry Addition?". The question being asked is simply, Since the last time you removed your Digital Tachograph Card have you performed any other work (not recorded on any type of Tachograph, i.e. Manual)? If so, this is the point to declare it.
Assuming no other work has been completed, use the arrow keys to highlight the 'No' on the screen and press the 'Enter' button.
Finally, "Begin Country" will appear and national identifier initials will falsh on the screen e.g. UK. Use the arrow keys to select the country you are presently in and press 'Enter'.
Step 3 - Changing the Mode
Once steps one and two are complete, all that is required is to record the different modes of operation (See Driver 1 Mode Change Button).
