When you try to open them directly, rather than by using the TDATA executable, the normal Acrobat reader doesn't display them.
Reason I ask is that, following from seeing the wiring diagrams on Rob's iPad yesterday I want to transfer the whole of RAVE to my iPad.
BTW. NO, this is NOT a knock off / fleabay copy of RAVE.
OR, alternatively, is anybody aware of a RAVE version ported to IOS please?
