Operating safety
Introduction
Risk of accident
G
Do not operate the tachograph unless the ve-
hicle is stationary. Your attention would oth-
erwise be diverted from the road and traffic
conditions and you could therefore cause an
accident.
Bear in mind that, at a speed of only
50 km/h, your vehicle is covering a distance
of nearly 14 m per second.
Repairs and modifications
!
The tachograph has been installed and
sealed by authorised
personnel. A vehi-
cle unit case must never be opened. No
tampering with or modifications to the
equipment or the speed sensor are per-
mitted.
Persons that modify this equipment
may be committing a punishable of-
fence, depending on the legislation in
the country concerned.
!
앫 Have the tachograph checked at a
specialist workshop if the outside is
visibly damaged.
앫 High voltages may lead to perma-
nent tachograph damage and to fail-
ure of the tachog
raph’s electronic
components. Damage to the tacho-
graph caused in this way invalidates
the warranty.
!
Interrupt the power supply to the tach-
ograph if:
앫
electrical welding operations are to
be carried out on the vehicle
앫 you expect that the vehicle will
require several jump-starting at-
tempts
Security inspection
!
The tachograph must be checked by a
specialist workshop at least every
2years.
The installation plaq
ue, fixed next to
the tachograph, states the date for
passed security inspection.
All seals and the installation plaque
must be intact for the security
inspection.
