The LS10's control panel is located on the top. It is a small, roundish, and basic affair, located about 8 inches behind the front of the projector. The projector's power switch is a couple of inches closer to the front. The lighting goes off when the projector is "working". The D version of the LS10 requires passcodes to let you access a lot of the controls that were remote accessed on the LS7 and the LS10i, and can be accessed from the control panel. The thought being, that The LS10d comes with an installer's remote, focused on what they need, and also with the idea that the LS10d customer wants a simple remote, and isn't tweaking the projector. The D, the LS-10d, is for folks that want simplicity, let the installers and calibrators do all the hard stuff. Things like focusing the lens with the D, will require the control panel (or passcodes), but not the LS7 or LS10i.
At the top is the Source button, and opposite it at the bottom, is the Menu button. Inside of them, are the four arrow buttons and a centered Enter key. Pretty standard stuff, and no extras.
That Power switch doubles as your full status system. Solid green indicates ready to power up (that's an unusual use of green, but, ok...) Blinking green is powering up, and when projecting (on), the light goes out. It also can blink red for overheating, red/green flashing for lamp issues. The DHD4 processor control panel.Finally there's solid red, which translates to: Call the doctor, theLS10 is demanding service.
The DHD4 Processor has its own large control panel, shown here, with Source selection, menu, navigation keys and power. There's a nice large and blue LED text display showing source and more.
