Your system administrator may ask you to access a diagnostics menu on your phone to test its hardware. You
can test your phone’s microphones, speaker, handset, third-party headset (if connected), keypad mappings,
touchscreen, and LEDs. See your system administrator for instructions on how to perform these tests.
To test your phone hardware:
1
Navigate to Settings > Status > Diagnostics > Test Hardware.
2
From the Test Hardware screen, select one of the following:
Audio Diagnostics
Keypad Diagnostics
Display Diagnostics
Touch Screen Diagnostics
Brightness Diagnostics
LED Diagnostics
The touchscreen on VVX 500/501, 600/601, and 1500 phones requires minor maintenance, but you may
periodically need to clean the touchscreen. Use a clean, dry, microfiber cloth—the kind you would use to clean
glass surfaces—to wipe the touchscreen.
Before you clean the screen, disable it so you don’t activate phone functions while you wipe the touchscreen.
To clean the touchscreen:
1
Navigate to Settings > Basic > Screen Clean.
2
Wipe the screen with a clean, dry, microfiber cloth.
3
Press any key on the phone dial pad to enable the touchscreen again.
Note: What happens if I clean the touchscreen, but it's still dirty?
Dampen a soft, lint-free cloth with an isopropyl alcohol and water solution of 50:50, and then wipe the
screen with the cloth. Always use the dampened cloth to apply the solution; never apply the solution
directly to the touchscreen, which could seep inside the screen or stain the phone. In addition, do not
use chemicals to clean the touchscreen.
