Although not my favorite remote control, the Nero's remote does a respectable job.
Taking a closer look, the backlight button is near the top, on the left, directly across from the power button (red).
Next comes a numeric keypad. This is used first, as your source selection. (i.e., 1 for video, 4 for HDMI1, etc.)
The remote control is a nice one. It's Silver faced (I can never find black remotes in my "cave-like" theater).
Below that are some buttons that I did not find intuitive. On the left a button with a black circle in the center. That's actually the OK, (enter) button. Opposite is the Escape btton. Below, the four arrow keys in a diamond shape.
Below that, the - and + toggle you between menus. Just below, two buttons. The left one takes you into the 3D menu, and the right one brings up the Memories menu.
The last two on the far left, are labeled zoom and focus, but are also labeled F1 and F2 (on the buttons). The Focus and Zoom are the defaults, but you can change them. (Theoretically, once your projector is mounted, zoomed and focused, you won't have any need for those two features unless your need to make changes due to an anamorphic lens). The final 3 buttons to the right of F2 are the Info button (next to F2/Focus). The Aspect Ratio button brings up a quick menu for changing the aspect ratio, and, finally, the button on the far, bottom right, DOESN'T DO ANYTHING! I'll assume that it is used on some other SIM2 projectors.
