Description

If CRT saver is enabled and the terminal is inactive for 30 minutes (no keyboard activity or input from a host computer), then the monitor screen goes blank to prolong the life of the CRT. No data is lost when CRT saver is active. Keyboard activity or input from the host computer re-activates the monitor.

When the monitor goes blank, the keyboard LEDs flash.
