The guide walks you through connecting the power cable, the 15‑pin video cable, and adjusting focus, zoom, and keystone to obtain a properly sized image. It also explains how to power the projector on and off using the POWER button.
Additional instructions cover the optional LT40RT remote control mouse kit, including required serial and mouse adapters, connection steps, and the functions of the remote’s buttons such as AUTO ADJUST, MAGNIFY, and LASER pointer.
Press and hold the POWER button for at least two seconds.
Make sure both the computer and projector are off, connect the cables as shown, then turn on the projector followed by the computer.
Use the keystone correction feature to adjust the image so it appears square to the screen.
