Downloading the proper firmware version
There are two firmware versions for the IN38. The version you should select depends on the languages your prefer for your projector's menu. The default version of the firmware ships with a wide selection of global languages. The European Language Pack version of the firmware has a different version number but identical functionality, with a very inclusive set of European languages for the menu.
If you'd like the default version of the firmware, please choose version 1.4 below. If you'd like the European Language Pack version of the firmware, please choose version 6.4 below.
