Thanks, but I guess I'm calling it by the wrong name.
What I'm referring to is the initial screen that shows up just by turning the device on. Mine stays on for 3-4 seconds. I'd like to set it to 10 seconds. I have a scrolling message that tells how to contact me if it is lost. This shows up just by turing the device on without having to enter the PIN and 3-4 seconds is too short to read the entire message
Following your directions works to change the time the screen remains on after it is initialized by entering the PIN but does nothing for the very first screen that shows up when one just turns on the phone.
Not sure what to call the very first screen that pops up.
