Looking at the schematic, I see 1 "Delay In" and 2 "Delay Out" labels. I'm guessing the "Delay Out" labels are references for where the circuit connects, but I am unsure what to do with the single "Delay In" label.

What looks like two opamps at the bottom of the schematics are actually part of the pt2399.
See the attached datasheet.

I'm aware of that, but that's not what my question was concerning.

In the middle of the schematic, there's a "Delay Out" from pin 11+12, and another at the bottom of the schematic leading to pin 13. I'm assuming those are connected, and separated due to space in the drawing.

Also on the bottom is "Delay In" from pin 15. Does that go somewhere? Is it just not connected beyond the cap and resistor to pin 16?

Delay in is just pin 15 of the pt2399 while delay out at the bottom of the schematics is connected to pin 12 of the pt2399 (it is also written in the schematics close to pin 12)

So my assumption of the two "Delay Out" labels being connected and the "Delay In" label not being connected to anything else in the schematic are correct?
