WARNING

Danger of losing text-figure correspondence when printing out.

For technical reasons, it can currently not be ruled out that the correspondence
between text and associated figure can be lost when it is printed out, even though
the display on the screen is correct.

• 

If the fault is not noticed, there is the danger that work will not be performed
correctly which can cause injury and damage.

• 

→ Therefore, always compare printouts with the screen display after printing them out. Correct
the printouts if they are faulty so that the content of the screen display matches that on the
printouts.

AVERTISSEMENT

Risque de perte de la correspondance texte-illustration lors de l'impression papier.

Pour des raisons techniques, il ne peut pas être exclu à l'heure actuelle que, même
en cas d'affichage correct à l'écran, la correspondance entre le texte et l'illustration
puisse être erronée sur l'impression papier.

• 

Si l'erreur passe inaperçue, on court le risque d'exécuter certaines opérations de
manière incorrecte pouvant conduire à des dommages corporels et matériels.

→ Comparez impérativement pour cette raison les impressions papier avec l'affichage à l'écran.
Corrigez-les en cas d'erreur de manière à reproduire correctement l'affichage à l'écran.

ATTENZIONE

Pericolo di perdita dell'abbinamento testo-immagine nella stampa.

Per motivi tecnici non è escluso che, nonostante la rappresentazione sullo schermo
risulti perfetta, durante la stampa venga persa la corrispondenza fra testo e
relativa immagine.

• 

Se tale difetto non viene rilevato vi è il pericolo che i lavori non siano eseguiti
correttamente; ciò può avere come conseguenza lesioni e danneggiamenti.

• 

→ Per questo motivo, dopo la stampa è assolutamente necessario confrontare le stampe con la
rappresentazione sullo schermo. In caso di errore si prega di correggere le stampe, così da
garantire la riproduzione esatta della rappresentazione sullo schermo.
