CHAPTER 5: SETTINGS
Clearing records with user-programmable operands is not protected by the command password. However, user-
programmable pushbuttons are protected by the command password. Thus, if they are used to clear records, the user-
programmable pushbuttons can provide extra security if required.
For example, to assign user-programmable pushbutton 1 to clear demand records, apply the following settings.
1.
Assign the clear demand function to pushbutton 1 by making the following change in the
 CLEAR RELAY RECORDS
