2. Select Screen Clean.
3. Wipe the screen with a clean, dry, microfiber cloth.
4. Press any key on the phone dial pad to enable the touchscreen again.
Note: If the touchscreen is dirty after cleaning, dampen a soft, lint-free cloth with an isopropyl
alcohol and water solution of 50:50 then wipe the screen with the cloth. Always use the
dampened cloth to apply the solution; never apply the solution directly because it could
seep inside the screen or stain the system. In addition, do not use chemicals to clean the
touchscreen.
