CAUTION
As the reflector used in the optical assembly is not symmetrical, correct positioning is necessary and will be
obtained when the hole in the reflector corresponds with the positioning pin of the optical cartridge.
The clear front glass has a structure spreading the light, created by lines on the internal surface. Therefore, it is
important that those lines be positioned vertically and not horizontally.
