Note
The common picture format can be *.gif/*.jpg/*.png/*.bmp. Yealink IP phones only
support the *.dob format logo files. Yealink provides PictureExDemo tool to convert
*.gif/*.jpg/*.png/*.bmp format to *.dob format. You can ask the distributor or Yealink FAE
for the PictureExDemo tool.
To customize a dob formatted logo file using the PictureExDemo tool:
1. Double click the PictureExDemo.exe.
2. Click Add button to open a *.gif/*.jpg/*.png/*.bmp file.
You can repeat the second step to add multiple original picture files.
Before uploading your custom logo to IP phones, ensure your logo file is correctly
formatted.
