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.
