Because the PUT did not have any artificial intelligence of its own, it was not able to translate body languages, rituals, or any other type of non-verbal communicatations. It was able to use broadband communications to communicate with a protocol droid if needed to enable more precise translations. Though the protocol droid did not have to be physically present for this to work, it did have to be within broadband receiver range. There was a companion unit for the PUT which had to be installed on the protocol droid which allowed it to broadcast any translation or helpful hints back to the PUT user.
