[AMSAT-BB] Help with TH-D74A

I am trying to store the odd-split frequencies for NO-104 (DTMF) in the memory of my TH-D74A. I downloaded the official manual, but I can't still can't figure out how to get anything in memory much less the odd-split frequencies. Can someone please point me to a video or a set of step-by-step instructions? I actually have the DTMF tones encoded, I just can't figure out the odd-split into memory part. Thanks in advance.
