Our screen does not have 3 dits on the upper right corner. It has a gear wheel and what looks like a timer. Also, it only has one light button on the lower edge of the frame. Should I take it back to store for a newer model?
We are in the process of rolling out menu updates to some touchscreens and as a result the steps are a little different if you have the version with the Settings wheel in the upper right corner.
Give this a shot
1) Tap the Settings icon in the far upper right and choose Devices
2) Enter your Master Code
3) Tap Touchscreen, and then Screen Configuration
From here you can Tap Screen Brightness, which will control the brightness level of the screen all of the time, or Automatic Screen Dimming -- this will allow you to choose to have the Touchscreen dim to a certain level after a set number of minutes.
