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.
