When auto aspect ratio mode is On, the shaft encoders are used to adjust the overall size of the circle
proportionately about the centre of the raster based upon the aspect ratio selected. The left knob adjusts
the top right corner of the circle and the right knob adjusts the bottom right corner of the circle.

When Force Centre is Off and, and auto aspect ratio mode is Off the left shaft encoder is used to adjust
the bottom side of the circle, and the right shaft encoder is used to adjust the right side of the circle.
4.8.4. Controlling the Circle Position
Press the POS button while the circle button is blinking to control the position of the circle. When auto
aspect ratio mode is Off and the Setup menu Force Centre item is set to no the left shaft encoder is used
to adjust the vertical position of the circle, i.e. move the circle up or down, and the right shaft encoder is
used to adjust the horizontal position of the circle, i.e. move the circle left or right. The remote panel
display will show the circle position while the POS button is brightly illuminated. The position adjust
function will be deselected after 3 minutes of panel activity, or when the another button is pressed.
If one of the auto aspect ratios is selected or the Setup menu Force Centre item is set to yes, then the
position of the circle is fixed to the centre of the clean aperture. The display will show Circle centred.
4.9. LOADING FACTORY PRESETS
The FACT PRESET button is used to recall the most recently used factory preset. Turn one of the shaft
encoder knobs to cycle through the available factory presets. The name of the selected preset will be
shown on the front panel display, and the selected collection of object settings will be loaded into to the
Graticule Generator. See Appendix B for definitions of the factory presets.
4.10. WORKING WITH THE USER PRESETS
The Graticule Generator has ten memory locations to store user defined presets. Each preset contains a
collection of object parameters that define what objects are on, and settings for the objects. There are ten
user-preset locations for each video standard. Each of the user preset locations can be write-protected, or
can left unlocked, so users can save their favourite settings. When the Graticule Generator is initialized at
the factory, the ten user preset locations are filled with ten of the factory presets. The state of the
SHIFT LOCK button determines whether user preset locations 0 to 4 or 5 to 9 will be selected with the
USER PRESET buttons.
Shift lock is On when the SHIFT LOCK button is brightly illuminated.
