Backlight
Backlight determines the brightness of the LCD screen display, allowing users to read easily in
dark environments. Backlight time specifies the delay time to change the intensity of the LCD
screen when the Skype for Business phone is inactive. Backlight turns off quickly if a short backlight
time is configured, this may not give users enough time to read messages. Backlight time is
applicable to T48G/T46G/T42G/T41P/T40P Skype for Business phones and EXP40 connected to
T48G/T46G Skype for Business phones.
Backlight Active Level is used to adjust the backlight intensity of the LCD screen when the phone
is active. Backlight Inactive Level is used to adjust the backlight intensity of the LCD screen when
the phone is inactive. Backlight Active Level is applicable to T48G/T46G Skype for Business
phones and the connected EXP40. Backlight Inactive Level is only applicable to T48G and T46G
Skype for Business phones.
