Request: Cables for newly released Lab599 TX-500MP

Good morning all,
So I got my cables earlier this week and finally sitting down with radio and computer. It was mentioned earlier in the thread that the radio can be listened to while it’s connected to the radio. I’d like to learn how this is done. I think I’ve got it but would like to see if it is the “correct” way to do it or not.
I’ve got it set to “listen to this device” w/ playback dropped down to computer’s speakers under the “Listen” tab beneath the “Recording” tab from Sounds. I can hear the incoming audio from radiog but when I Tune up I hear the transmitted “beeeeeeeep”. Is this the correct way to do this? I’ve checked power out on radio so I think it is.
