Wallpaper is a picture used as the background of the phone. The phone comes with a default picture. You can change it to a built-in picture or custom wallpaper from personal pictures.

The wallpaper is only applicable to color screen phones and expansion module EXP50 (connected to the T57W/T54W/T53W/T53/T53C phones)/expansion module EXP43 (connected to the T48U/T46U/T43U phones).

You can change the wallpaper to any built-in picture or custom picture.

On T57W/T48U/T48S/T48G phones or video phones, you can also separately set the wallpaper when the DSS key list is unfolded, avoiding the display of the line key labels to be blocked by the background picture.
