RISK OF EXPLOSION!
Please observe the following when
loading and unloading hazardous
goods:
• Both card drawers must be closed.
• The printer drawer must be closed.
• The cover flap of the front interface
must be closed.
• Do not press any buttons on the
tachograph.
• No workshop, control or company
card must be inserted.
► Particularities in relation to the
operation
To prevent explosions, the ADR version
of the DTCO 4.0 is reduced to internal
functions only with the ignition switched
off in corresponding hazard areas (unlike
the standard version).
Therefore, you must switch on the igni-
tion outside of the hazard area if you
wish to operate the ADR version of the
DTCO 4.0.
