Syntax: CRT(SAVE) <minutes>
(default: 0)

This parameter defines how long after last key press the screen is shown until
it's switch off (screensaver function). If you press a key again, screen is
switched on. If you don't use screen for long time, it's better to completely
switch of the monitor (can save more than 200 kWh each year).
