Programming 20
Screen Locking
This setting is used to lock out the user from changing most of the program menu
settings. When the “Loc” setting is saved, the only program menus that can be
changed are “tod” and “tor”. The program menu settings will appear as normal but
their values will not be able to be changed. (Note: The hidden menu can always
be accessed and settings within the hidden menu can always be changed, even if
“locked”.)
The display will show “Loc” or UnL” depending on the last saved setting (default to
“UnL” if EEPROM has no saved value. Toggle between “Loc” and UnL” with the “+” or
“-” keys.
Pressing the “Status” key will save the setting, exit the Hidden Menu and return to the regular time of day Service Mode display.
