"<Definition> Indicates the method used to select the Brightness Level.
A DMS may subrange the values supported, as indicated.
other (1) - indicates that the Brightness Level is based on a

photocell status. Support for this mode shall be supported if

timer. The details of this timer are not defined by this standard.
manual (4) - indicates that the Brightness Level must be changed via
the dmsIllumManLevel object. This mode is DEPRECATED.
manualDirect (5) - indicates that a user can change the brightness output to
any of the brightness levels supported by the sign. This is not the same

dmsIllumBrightnessValues object. This mode is mandatory, if this is the
manual mode that the DMS supports.
manualIndexed (6) - indicates that a user can change the brightness output
to any of the rows defined within the table of the
dmsIllumBrightnessValues object. This mode is mandatory, if this is
the manual mode that the DMS supports.
The DMS must support either one of the manualXxx modes.
When switching to any of the manual modes (manual, manualDirect, manualIndexed) from any other mode, the current brightness level shall automatically be loaded into the dmsIllumManLevel object.
