7.6.6 User ID card (optionally available as an accessory)
The device number of the appliance and a unique
user number are stored in encrypted form on
the user-ID card ( Fig. 35 ). The user-ID card
therefore works only in the appliance with the
corresponding serial number.
Every login process with the user-ID card is
logged in the internal Flash memory of the
controller.
If the user-ID card has been inserted, the menu
item ID-LOCK also appears in the SETUP menu
(see Chapter 7.2 Basic appliance settings (Setup)
on page 46 ). If the setting is set to ON, the test
chamber is locked against all alterations once
the card is removed.
The lock via the user-ID card is displayed via the flashing key icon
on the operating
panel (see also Fig. 20 on page 28 ).
If the test chamber is locked via the user-ID card, no programme operation with the
MEMoryCard XL is possible, since this card could be removed at any time and modified
externally.
