This early version of the Plex model has burnt out its spellcheck chip. The result is a series of phone messages that have all been written down phonetically, meaning Plex is writing exactly what he hears.

So when Plex writes TELLUHFOWN, he probably means "TELEPHONE;" And when he jots down ROWBAHT, he's really saying "ROBOT."

And if that wasn't confusing enough, Plex 1000 didn't bother putting spaces between his words, meaning each message is just one long phonetic nightmare.
