Fitting more memory to an Echelon
The amount of show memory fitted to an Echelon as delivered from the factory is
satisfactory for most shows. However in some circumstances this may be
inadequate. Examples of such circumstances are:
•
When a large amount of blocking cues are required
•
When a large number of cues or cuelists are required
In such circumstances additional memory may be fitted to the console. Note that
fitting extra memory to the console will not improve performance.
The amount of free memory can be seen at any time by pressing the “Setup” button,
followed by the “Panel” button in the toolbar. The free memory will be displayed near
the centre of the main LCD.
