6.2 Notes on operation
During operation observe the following points:
• Check your entries and changes before you leave the menu.
• Use only your fingers to press the keys.
Do not press keys with hard or pointed objects, otherwise you
may damage the sealed keypad (e. g. pencil).
• Protect menus with an access code.
Access code
Please note
An access code can be entered to protect against unauthorized or
inadvertent incorrect operation.
The default code is "CODE def = 0", which means that an access
code is not defined.
Defining access codes Proceed as follows:
1 In the SETUP menu under "Code def.", enter the new access
code (number between 1 and 999).
2 Press the key to confirm.
Please note
The access code is automatically saved after 1 hour if the key is
not pressed again.
Blocking with access code To immediately block the unit using the access code, the code
must be set and saved as a number in the main menu (not "Code
def.").
Values may still be viewed without the access code, however they
cannot be edited.
"Code ???" appears in the menu if an unauthorized access is
attempted. The previous settings are redisplayed.
Values in the protected menus can only be edited if the correct
access code is set in the main menu.
