Harvest - the arrows grid

I have a few questions about this puzzle in the secret room:

1) Do you have to go through all squares, or can some remain blank?
2) Is more than one answer possible?
3) Is there some sort of signal when you have laid out the arrows correctly?

I know where to start and where I should end up. I'm just confused about the middle part.

Hi Row,

1. No, you don't have to go through all squares, just specific ones.
2. I tried but found only one. Maybe Mike can clear this part up.
3. No signal I found on the panel itself or I'm tone deaf. I had to go through and find for myself where to go.

I made a grid on a paper, wrote by trial or error where I can go and eventually found the path.

IMPORTANT: take careful notes on exactly how the arrows go--you will need to know that in the next sequence...

Hi everyone. There is only one direct path through the corridors. There is no audio or video signal to let you know when you have the arrows set correctly - as MaG said, it's trial and error. Rowan, if you want a hint, let me know.
