Clean the Touchscreen
The touchscreen on VVX 500/501 and 600/601 phones requires minor maintenance, but you may need to 
clean the touchscreen periodically. Use a clean, dry, microfiber cloth—the kind you would use to clean 
glass surfaces—to wipe the touchscreen. Do not use chemicals to clean the touchscreen.
Before you clean the screen, disable it so you don't activate phone functions while you wipe the 
touchscreen.
Procedure
1. Navigate to Settings > Basic.
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.
