Apple 20Display manual Protecting your monitor from theft, Troubleshooting

Page 40

To clean the screen of the monitor:

1Turn your computer and monitor off.

2Disconnect the monitor’s power plug from the back of the monitor. (Pull the plug, not the cord.)

3Use a mild, non-abrasive cleaner on a soft cloth and wipe the screen. Don’t spray the cleaner onto the screen, because the liquid may drip inside the monitor.

Protecting your monitor from theft

The slot on the back of the monitor is for connecting a security lock. It lets you attach a narrow, flexible cable that you can use to secure your monitor (and the rest of your computer system) to prevent theft. Security locks are available from an Apple-authorized dealer or service provider.
