■ The ISDN cable(s) must remain disconnected from the
telecommunications system until the card has been
installed in the system.
■ The installation of the card in the host system must be
done in a way that ensures at least 2mm of air gap
between the Printed Circuit Board (PCB) card and any
other components in the host system, so that the
unsafe area remains located only on the ISDN card.
■ The ISDN card must only be used in a host system with
a screw-down cover / lid in order to protect the
operator.
