Storage temperature tolerance:
•If the installation of the unit is done in a room with soot and/or smoke over a longer period, even small amounts of these substances will affect the device.This unit cools its optical components, which produce a great amount of heat, by sucking in air. If the optical circuits get dirty, this might lead to malfunctions, like the video images becoming darker or a deterioration of the color development. Dirt sticking to the optical components cannot be removed.
| Please be careful to perform |
| the installation at a certain |
