I've traveled with the zeppelin to some remote Ocean Platform and now I want to go up with the elevator. You have to input some code. In the journal I've found this note of some codes: TR M BR B - EL B BR. Maybe it has something to do with these code, however the symbols on the display do not seem to match these codes. It looks if some parts of the letter or cipher is missing.

Anyone who knows how this is suppose to work?
