Wallpaper
Wallpaper is an image used as the background of the IP phone and EXP50 (if connected). Users
can select an image from IP phone’s built-in background or customize wallpaper from personal
pictures. To set the custom wallpaper as the IP phone/EXP50 background, you need to upload
the custom wallpaper to the IP phone in advance. The wallpaper is only applicable to SIP-T54S,
SIP-T52S, SIP-T48G/S, SIP-T46G/S, SIP-T29G IP phones and EXP50 (connected to the SIP-
T54S/T52S IP phones) expansion module.
For SIP-T54S/T52S IP phones, you can also set a custom picture stored in your USB flash drive
as the wallpaper. In order to do this, make sure the USB flash drive containing pictures is
connected to your phone. For more information, refer to
Yealink phone-specific user guide
.
You can set the wallpaper for the SIP-T54S/T52S/T48G/T48S/T46G/T46S/T29G IP phones idle
screen (for T48G/S, the DSS key list is folded) and EXP50 (connected to the SIP-T54S/T52S IP
phones) expansion module.
You can also separately set the wallpaper for the SIP-T48G/S IP phones when the DSS key list is
unfolded, avoiding the display of the line key labels to be blocked by the background image.
