Logo Customization
Logo customization allows unifying the IP phone appearance or displaying a custom image on
the idle screen such as a company logo, instead of the default system logo.
You may need to resize your logo file to fit the LCD screen. The image logo screen and the idle
screen are displayed alternately. The logo may affect the invisibility of time and date, soft keys
and the label of current account on the LCD screen.
