Protect Level Section 5-2
5-2 Protect Level
Four levels of protection are provided on the E5CN, operation/adjustment pro-
tect, initial setting/communications protect, setting change protect, and PF key
protect (E5AN/EN only). These protect levels prevent unwanted operation of
the keys on the front panel in varying degrees.
To move from the operation level to the protect level, press O and M Keys for
three seconds (see note) or more.
Note The time taken to move to the protect level can be adjusted by changing the
Move to Protect Level Time parameter setting.
Parameters that are protected will not be displayed and their settings cannot
be changed.
