I just received an Ultra via R&L.? My HW version is V0.4.5.1.?
I noticed that the ports on the left side are labeled differently
from what I have seen in videos and images.? The top one is
labeled "Cal" and the bottom one is labeled "RF."? I was expecting
high and low ports.? Did the Ultra change or is this just
labeling?
