3.7.2. Controlling the Box Modes
When the box object is selected, the MODE button is used to control its modes, such as aspect ratio, and
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 control
for the box.

whether its horizontal and vertical dimensions can be independently controlled.
Select Off to allow the box object's horizontal and vertical dimensions to be independently controlled.
Select one of the specific aspect ratios to constrain the horizontal and vertical dimensions so that the
aspect ratio of the box object is maintained.

3.7.2.3. Centring the Box on the Raster

This item is used to control whether the box object is centred on the raster or not. The centre item is only

Select H + V to force the box object to be centred on the raster.
Select off to allow the box object to be moved off centre. In this MODE it is possible to independently
position each line on the box, or to position and size the whole box, depending on the settings of the
aspect ratio MODE item and what CTRL SEL item is chosen.
