on, e.g. flying stars "starfield simulation," renew themselves. Pay attention to the length of
time the backlighting is activated.
• The following applies to screen savers which turn off the backlighting: Each time the
backlighting is turned on, its life is reduced by 50 minutes.
Consider the following carefully:
• Screensaver
• Switch off the backlighting regularly
