Section 4— Switcher Operations

Clearing the Switcher

It is best to reset the switcher to a known state before beginning
any of these procedures. Step #2 below clears all switcher areas
except crosspoints.

To bring the switcher to a “known” state, you will want to clear
either all, or just certain parts of the switcher. The

Clear Working

Buffer

(CWB) button is used to clear selected areas of the

switcher’s work buffer. The CWB controls the areas that are
delegated on the E-MEM Subpanel. First, you must delegate the
levels you wish to clear. (You can use

ENABL ALL

to insure you get

all of them.)

The CWB is located on the E-MEM Subpanel. The following clear
functions are available:

1.

First recall the GVG defaults to the Clear Working Buffer.
(Select top menu Config, User preferences, Define default,
GVG defaults and Do save).

2.

Second, enable all areas of the switcher to be cleared by
selecting them in the E-MEM Subpanel, or press

ENABL ALL

to select all areas of the switcher.

3.

To clear the Current Working Buffer — except Keyers:

Single press of the

CLEAR WORK BUFR

button: (E-MEM

Subpanel)

Clears Current Working Buffer (CWB) to user-defined
defaults. The key memory portion of the CWB is unaffected
(for example, video processing or clip and gain). All non-key
memory parameters are cleared for enabled levels.
