You can only obtain a reset code from your local Endress+Hauser service organization.
The code must be calculated explicitly for every device.
1. Note down the serial number of the device.
2. Read off the Operating time parameter.
3. Contact the local Endress+Hauser service organization and tell them the serial
number and the operating time.
 Get the calculated reset code.
4. Enter the reset code in the Reset access code parameter (→  137).
 The access code has been reset to the factory setting 0000. It can be redefined
→  140.
For IT security reasons, the calculated reset code is only valid for 96 hours from the
specified operating time and for the specific serial number. If you cannot return to the
device within 96 hours, you should either increase the operating time you read out by
a few days or switch off the device.
10.7.2 Write protection via write protection switch
Unlike parameter write protection via a user-specific access code, this allows the user to
lock write access to the entire operating menu - apart from the "Contrast display"
parameter.
The parameter values are now read only and cannot be edited any more (exception
"Contrast display" parameter):
• Via local display
• Via HART protocol

→  144. In addition, on the local display the  symbol appears in front of the
parameters in the header of the operational display and in the navigation view.
