3.4.2. Controlling the Grid Modes
When the grid object is selected the MODE button is used to control whether it is centred or not. Press
the MODE button until the desired mode item is shown on the front panel, along with the current setting.
To select one of the other choices for that mode item, turn one of the shaft encoders knobs. When you
have chosen the desired setting for the mode item press the MODE button again to save the new setting
and view the next mode item. Continue pressing the MODE key until you see the message Mode
Select Off. The shaft encoders revert to controlling the selected attribute for the grid that is also shown
on the ctrl line of the OSD.

Centering the Grid on the Raster
Centre:
H + V
This item is used to control whether the grid object is centred on the raster or not. The centre item is only
available when the SETUP menu item force centre is set to off.
Select H + V to force the grid object to be centred on the raster. The OSD will show centred.
Select off to allow the grid object to be moved off centre. The OSD will show not centred. In this MODE it
is possible to independently position each line on the grid, or to position and size the whole grid,
depending what CTRL SEL item is chosen.
3.4.3. Controlling the Grid Attributes
When the grid object is selected the CTRL SEL button is used to select which of its attributes (such as
colour, line width, position, size, or individual lines of the object) will be adjusted by turning the shaft
encoder knobs. Press the CTRL SEL button until the desired CTRL SEL item is shown on the front panel.
When you have chosen the desired CTRL SEL item press the GRID button again or turn one of the shaft
encoder knobs to begin controlling the selected attribute of the grid. The selected attribute for control will
show on the ctrl line of the OSD.
The items that are shown in the grid CTRL SEL menu depend on the MODE settings and the settings in
the SETUP menu. In the sections describing the CTRL SEL items, the relevant settings from the grid
MODE and SETUP menus are shown where necessary.
