3.1.4
Code Number
To protect the settings against unauthorized access or an inadvertent change,
the settings should be locked using a freely selectable code number. The
settings can be displayed, but not changed. If an attempt is made, then
“Code???” is displayed before reverting to the former setting.
After switching on, after a RESET or generally after one hour without
pressing a key, the code number is set to 0. If the unit is locked, settings
can only be changed after entry of the correct code number. Locking can
be selected in the “Lock Setting” menu.
To alter the number again, enter the new code number in the SETUP menu
under “Lock code set”. If you then want to block access to unauthorized
operators, immediately change the code in the SETUP menu to another
number and set to “Locked” in the “Lock Setting menu”.
In order to provide general access, select “Unlocked”. This means that
changes are possible at any time without having to enter a code. Code is
no longer displayed in the main menu. However, another code number can
now be entered and access denied to all those operators who do not know
the new number.
The unit is delivered with the “Lock code set” = 0, “Lock setting” =
Unlocked. If the code number is forgotten enter the back entry code 911.
You can only alter the values in the protected menus once you have set the
correct code number in the SETUP menu and thus proved that you are an
authorized operator.
