click to Enlarge. So close
While I'm not a fan of side control panels (Epson, Sony), because I tend to use control panels a lot while testing, for most folks it really won't matter much, since they will rely on the remote control.
One thing though, I refer to it as being on the side, but I should point out that the power button and source switch are located on the top of the projector. The control panel functions are rather typical.
Closest to the front of the buttons is a large Menu button. To its right, the four arrow keys on a rocker (diamond configuration, with a center Enter button), I'm not a fan of the rocker type four way around the enter button, but, its functional. Finally closest to the back, is the Escape key which takes you back up a level in the menus.
It's that simple, should you misplace your remote!
