display light on 1140

[beastm0d3]

hello everyone. long time follower first time post(er). I've tried to locate the answer here on TTF but can't seem to find it. That or I'm an idiot.
I have several (300+) 1140e units that have the back light display that comes on periodically. When the light comes on, it stays on for a couple of minutes or so then dims down. I did some individual phones to cut that time back to 5 secs but it still lights up periodically. I was thinking if there is a setting i can change from the meridian cs1000 unit. Any help would be awesome.

Dont think there is anything elase which controls 11xx Phone display back light other that the back light setting in the phone itself.

Think if you add a tftp provisioning server then that is something you can put in the 1140e.cfg
