Handling the tachograph cards
Please observe the following instructions about using the tacho-
graph cards:
• Handle the tachograph cards carefully in order to avoid loss of
data.
• Do not bend or fold the tachograph cards and do not use them
for anything other than their intended purpose.
• Do not use damaged tachograph cards.
• Keep all contact surfaces clean, dry, and free of grease and oil
(always use the protective cover).
• Protect the card from direct sunlight (do not allow it to lie on the
instrument panel).
• Do not place it in direct proximity to strong electromagnetic
fields.
• Do not use the card beyond its period of validity. Apply for a new
card in a timely manner before expiry.
Attention!
Possession of a tachograph card authorizes the holder to use the
digital tachograph. The tachograph cards are person-specific
(workshop cards are company-specific) and are therefore not trans-
ferrable to others!
An accredited workshop must securely retain, use, and administer
its workshop card and PIN; workshop cards and PIN may not be
made available to third parties!
An accredited workshop must ensure secure communication
between the DTCO 1381 and workshop card!
Loss of the workshop card must be reported immediately to the
issuing authority / institution!
Obey the valid legal regulations in your country surrounding
workshop cards!
Obey the instructions of the issuing authority / institution and the
card manufacturer!

Installing the DTCO 1381
Installation of the DTCO 1381 components does not require any
interventions in the vehicle’s safety equipment. When installed cor-
rectly, the vehicle’s equipment and driving characteristics will
neither be changed nor influenced.
Observe the following general instructions for the installation
of the DTCO 1381 components:
• Always observe the manufacturer’s instructions, particularly
when working on the onboard power supply.
• Make sure that the vehicle's ignition is switched off.
• Make sure that the legal regulations regarding installation room
are complied with, that there is sufficient room to operate the
DTCO 1381, and that the display is positioned in a way that
affords optimal readability.
• When installing the DTCO 1381 components, avoid damaging
the existing cables in the vehicle or unintentionally loosening
plug-in connections.
• Before removing covers and similar vehicle parts, obtain infor-
mation on proper dismantling procedures in order to prevent
damage to the parts.
• Refer to the connection diagrams for information on the
location of fuel, hydraulic, compressed air, and electrical lines.
• When separating plug-in connections, do not pull on the cable,
but rather on the plugs or the proper unlocking systems only.
• For mounting tasks, use only original Siemens VDO Automotive
installation parts and accessories. Install undamaged compo-
nents only.
• During installation, be absolutely certain that the DTCO 1381
components do not influence or restrict the vehicle’s function-
ality in an undesirable way.
• Instruct the driver / company in the use of the DTCO 1381 and

sources of heat cannot cause damages, and that the lines cannot
cause any undesired interference or disturbances.
General security instructions
While handling a DTCO 1381, which has not yet been activated, the
approved recording equipment manufacturer, vehicle manufacturer,
installer, or a workshop must guarantee the security of the
DTCO 1381.
Maintenance
Cleaning Do not use any volatile solvents, such as alcohol, diluting agents,
naphtha, or abrasive cleaning solutions when cleaning the devices.
When dirty, clean the housing, the display and the function keys
using a slightly moistened cloth.
Operational notes Avoid excessive impacts and vibrations. Do not use sharp or pointed
objects (such as pens) to operate the keys.
Keep the printer drawer closed at all times in order to avoid damages
and contamination.
Caution! Danger of fire due to short circuit
Damaged cables can cause short circuits, undesired interferences, or
disturbances.
Always replace damaged cables immediately!

1.1.1 Brief description
DTCO 1381 The DTCO 1381 digital tachograph is an EC recording equipment
that complies with the requirements of CR (EEC) 3821/85, annex I B.
It is used to register, save, display, print, and output driver-based and
vehicle-based data. The data is saved in the DTCO 1381 device
memory and on inserted tachograph cards.
The standard display provides an overview that shows the time,
current speed, and distance. It also shows the set activities and
symbols of the inserted tachograph cards, see chapter 3.2 "Display
variations", page 3-5.
An internal diagnosis function monitors the system and automati-
cally notifies if events or faults appear.
Events, faults, or warning messages are displayed optically.
KITAS 2171 KITAS 2171 is part of the EC recording equipment, it provides real-
time signals and cryptologically encoded data. The signals serve for
recording the distance and speed.
The DTCO 1381 can detect external interferences and influences by
monitoring the data communication with the KITAS 2171 and com-
paring this to the real-time signal.
Printouts The integrated printer on the DTCO 1381 can print data from the
memory and the tachograph cards. The types of printout, the
format, arrangement, and data contents are defined in CR (EEC)
3821/85, annex I B.
Printer paper The printer paper is approved for use with the DTCO 1381 and
exhibits a corresponding mark of approval. The paper is a special
thermal printing paper.
Display instrument A display instrument is located directly in the driver’s field of vision.
The operational check " " (shown in the color amber or orange)
brings attention to messages from the DTCO 1381.
The display instrument is not part of the EC recording equipment.
Display instruments are designed for specific vehicles and will not be
covered in this documentation.
