*1 The average brightness output value of all factory products measured at the center of the screen in normal mode.
*2 The measurement method and labeling method are based on the ISO/IEC 21118: 2020 international standard. This value is the average of all manufactured products.
*3 At this time, the brightness output is reduced to approximately 50%. Comply with IEC62087: 2008 Broadcast Contents standard, normal mode, dynamic contrast mode: 3, under the conditions of a temperature of 30°C, an altitude of 700 meters and a particle concentration of 0.15mg/m³. The use environment and conditions will affect the brightness output halved time. The replacement cycle of parts other than the light source may be shorter than that of the light source. After approximately 20,000 hours of use, it is recommended to contact the dealer for cleaning and inspection of the equipment.
*4 When ET-DLE055C is cted, the optical axis movement function is not supported, and the optical axis is fixed when ET-DLE035C is cted.

(镜头部件 用户手册)
Do not give a shock or excessive load to the projector or the lens components as the projector and lens components contain precision parts.
When shipping the projector with the lens,remove the lens before shipping the projector. The lens and the lens shift mechanism may encounter damage caused byimproper handling during transportation.
Before removing or installing the lens, be sure to turn off the projecttor, wait until the cooling fans stop, andunplug the power cord.
Do not touch the lens surface when removing or installing the lens.
Keep fingerpeints, dust or oil off the lens surface. Do not scratching.
Work on a level surface with a soft cloth under it toavoid scratching.
When using the lens unit, set the lens shift adjustment to the center of the screen.
Adjustment to the lens shift adjustment to the position other than the above can cause the edges of the image to become dark or can cause some shadows.
