Prolog information
For J100 R4.1.0.0 and higher, you can also add up to 5 separate background images for use by JEM24 modules.
  • This feature requires the J100 phones to use J100 R4.1.0.0 or higher firmware.
You can add the following commands to the 46xxspecials.txt file to control the use of the files.
  • SET BACKGROUND_IMAGE_JEM_FOLLOW_PRIMARY <N>
    Sets whether the JEM24 button modules use a different image settings from the main screen. Where <N> is:
    • 0 = The JEM24 image settings can differ from the main screen.
    • 1 = The JEM24 uses the main screen image settings.
If SET BACKGROUND_IMAGE_JEM_FOLLOW_PRIMARY is set to 0, you can use the following commands:
  • SET BACKGROUND_IMAGE_JEM <filenames>
    Set the list of JEM24 image files to download to the phone. You can specify up to 5 filenames, separating each name with a comma. See Image File Paths.
  • SET BACKGROUND_IMAGE_DISPLAY_JEM <filename|N>
    Set the default file to show as the JEM24 image, where either:
    • <filename> is the name of one of the images requested using SET SCREENSAVER_IMAGE.
    • <N> selects one of the phones 7 default images using values 0 to 6.
    • You can specific a comma-separated of images to use with SET SCREENSAVER_SLIDESHOW_INTERVAL.
  • SET BACKGROUND_IMAGE_SELECTABLE_JEM <N>
    Sets whether the user can select the JEM24 image through their phone menu. Where <N> is:
    • 0 = Users cannot change the JEM24 image.
    • 1 = Users can change the JEM24 image, overriding any previous set image. This is the default if the command is not specified.
