This manual introduces how to use the projector safely, including the projector's features, operating methods and precautions.
The EMP-400W projector offers short‑distance projection, with a minimum recommended distance of 54 cm (21 in.) that yields an image of about 110 × 67 cm (43 × 26 in.). It supports WXGA (16:10) sources and includes network‑based control via a LAN connection, as well as RS‑232C for computer control.
The guide details all hardware components, including the front foot lever, focus ring, security slot, lamp cover, and various input ports (Computer1/2 video, Audio1/2, S‑Video, LAN, RS‑232C). It also covers security functions such as password protection, operation lock, and anti‑theft devices, plus maintenance tasks like cleaning the lens, air filter, and replacing the lamp or batteries.
