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 

 (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 

 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 

 

to select all areas of the switcher.

3.

To clear the Current Working Buffer — except Keyers:

Single press of the 

 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.
