Default operation uses the single image 96xxiposs.jpg which you can replace with your own image. If using a customized 46xxsettings.txt file, you can implement set the idle timeout for displaying the screensaver and the image name.
Procedure
Create a customer JPG file meeting the requirements.
For this example we used the file name logo.jpg.
Download the current 46xxsettings.txt file from the file server being used by the phones.
Add the following lines to the 46xxsettings.txt file:
## SET SCREENSAVER filename
SET SCREENSAVER logo.jpg
## SET SCREENSAVERON time in minutes before activating
SET SCREENSAVERON 40
Using Separate Images for Each Phone Type
Added the above to the start of the file affects all types of phone. Adding different settings to each of the different MODEL4 sections of the file for each phone type allows separate images to be used for each phone type.
Upload the new files to the file server used by the phones.
Reboot the phones in order for them to load the new settings and image.
