Automatic fan control system
When the temperature sensor detects a low temperature, the fan speed is reduced
automatically to suppress fan noise, achieving 37dB.
The temperature sensor is located near the air inlet to improve response and optimize
speed.

• LV-IL03, long focus zoom lens
* The projection distance is approximate.
* The ultra wide angle lens (LV-IL01) is mainly designed for rear projection and
assumed to be used with "lens shift U/D ratio of 1:1" for ultra wide angle projection.
If the lens is shifted from the center, the image may be distorted.
