Using On-Screen Controls
The Production Unit uses a variety of on-screen buttons, scroll-
bars, checkboxes and other controls. These on-screen controls are
generally operated by moving the
pointer (shown left) over them,
and left clicking. A summary of the different controls is provided
below:
The simplest on-screen control is a button (example shown left). A button
will be marked with a label, describing what it does. For example, the but-
ton shown here is labelled
Display
. Clicking it would put the Production
Unit into Display Mode. To operate a button, use the mouse to move the
pointer so that it is over the button, then left click.
A
scrollbar (shown left) is used to move up and down within a list of
items. To use the scrollbar, click in the white area either above or below the
handle to move up or down by one page of items at a time.
Alternately, to move up or down one row of items, left click on the up or
down buttons on the scrollbar.
A
checkbox (shown left) is used to turn certain options on and off. For ex-
ample, checkboxes are used to set screens to display or not display on par-
ticular days. If the option is turned on, the checkbox will appear as a green
tick. If the option is turned off, the checkbox will appear as a red cross. To
change the checkbox, point to it and click.
A
slider (shown left) is similar to a scrollbar. It is used to adjust settings
like volume of sounds, or the speed of a scroller. To adjust it, click and drag
the handle. Left is lower volume/speed, right is higher.
A
text box (example shown left) is used to enter information into the Pro-
duction Unit. This includes names of sequences or screens, etc. Click on the
text box, then enter your text using the keyboard. A flashing cursor marks
where the next letter pressed will appear. Use the cursor keys to move the
cursor around within a text box.
