Dimensions
Width : 44 mm (1-23/32"), Length : 105 mm (4-1/8"), Height : 20.5 mm (13/16")
*1 Measurement, measuring conditions and method of notation all comply with ISO/IEC 21118:2012 international standards.
*2 This is an average value. It may differ depending on individual product.
*3 When the projector is operated at an elevation of 1 400 m (4 593') or less, if the ambient temperature exceeds 35 °C,
[Lamp control] will be switched to [ (Eco)] automatically to protect the projector; When the projector is operated at an
elevation between 1 400 m (4 593') and 2 700 m (8 858'), if the ambient temperature exceeds 30 °C, [Lamp control] will be
switched to [ (Eco)] automatically to protect the projector.
