Make sure that the exhaust from the projector or otherequipment, or the air from the air conditioner does not blow toward the front of the projector.f Places with sharp temperature fluctuations such as near lights (studio lamps): Doing so may shorten the life of the lamp, orresult in deformation of the outer case due to heat, which may cause malfunctions.The operating environment temperature of the projector should be between 5 °C (41 °F) and 40 °C (104 °F) when usingit at elevations lower than 1 400 m (4 593') above sea level, between 5 °C (41 °F) and 35 °C (95 °F) when using it at highaltitudes (between 1 400 m (4 593') and 2 700 m (8 858') above sea level), and between 5 °C (41 °F) and 30 °C (86 °F)when using it at high altitudes (between 2 700 m (8 858') and 3 000 m (9 843') above sea level).f Near high-voltage power lines or near motors: Doing so may interfere with the operation of the projector.rBe sure to ask a specialized technician when installing the product to a ceiling.This requires an optional ceiling mount bracket. Be sure to use the Projector Mount Bracket together with the ceiling mountbracket for high ceilings or low ceilings.Model No.: ET-PKL100H (for high ceilings), ET-PKL100S (for low ceilings), ET-PKL420B (Projector Mount Bracket)rWhen using the projector in the elevation of below 1 400 m (4 593'), make sure [Highland] is set to [Off].Failure to do so may shorten the life of the internal parts and result in malfunctions.rWhen using the projector in the elevation of above 1 400 m (4 593') and below 2 700 m(8 858'), make sure [High land] is set to [On 1].Failure to do so may shorten the life of the internal parts and result in malfunctions.rWhen using the projector in the elevation of above 2 700 m (8 858') and below 3 000 m(9 843'), make sure [High land] is set to [On 2].Failure to do so may shorten the life of the internal parts and result in malfunctions.rDo not install the projector at elevations of 3 000 m (9 843') or higher above sea level.Failure to do so may shorten the life of the internal parts and result in malfunctions.rDo not tilt the projector or place it on its side.Do not tilt the projector body more than approximately ±30 degrees vertically or ±15 degrees horizontally. Over tilting mayresult in shortening the life of the components.Within 15°Within 15°Within 30°Within 30°Chapter 1 Preparation - Precautions for use
