-> Specific power voltage isn’t required. Free voltage, 12 to 240VDC and 24 to 240VAC.
-> Light-reception amount can be display with 5-point level lamp and so it is easy to check light-reception margin or dirty lens surface and dislocation of optical axis.
-> Self-diagnosis function that checks light-reception margin provides with projector.
-> This output is executed when level of light-reception amount is lower than specific value because of dirty lens surface or dislocation of optical axis.
