Cleaning the Touchscreen

The touchscreen requires very little maintenance. Periodically, however, you may need to clean it. Use a clean, dry, microfiber cloth—the kind you would use to clean glass surfaces—to wipe the touchscreen. This type of cloth is available from many office supply stores.

Before you clean the screen, disable it so you don’t activate phone functions while you wipe the touchscreen. To enable the touchscreen again, press any key on the phone console.

To answer a call while the touchscreen is disabled, pick up the handset. Or, press or and tap Answer.

To clean the touchscreen:

1Tap Settings from Home view, and tap Basic > Screen Clean.

2Wipe the glass with a clean, dry, microfiber cloth.

3To enable the touchscreen again, press any key on the phone console.
