Introduction
SET·UP
5.1 This section describes the Model 924 VDT screens displayed in set-up.
With these screens you can review and alter the operating features, such as reverse video, VDT baud rate, and the number of columns displayed. Figure 5-1 shows the relationship between the set-up screens.
To enter set-up to use these screens, hold the Alt and Shift keys while pressing the Backspace key. To exit set-up once you finish using the screens, repeat this key sequence.
The VDT holds the set-up options in a nonvolatile RAM (NVR) memory. The selected features are retained even when power is off. The default settings are also retained in nonvolatile memory, so they can be restored during set-up after they have been changed.
