NewBee Pulley question

[tx77057]

Good morning all.

I recently purchased a used whitetail 2 bow. It came with all of the accessories. I sort of figured out that the extra cams are marked for the correct inch of draw, I.E. 28 through 32 on all of the cams (it currently has 30's installed and that reflects the corresponding draw length of 30" marked on the bow sticker)., It also has Allen bolts on each of the limbs for adjusting the draw weight. My question is:
At each starting point of the cable, there is a small round pulley (actually it is more of a stationary wheel because it does not turn) that has a star shaped design in the middle with letters. for example, A, B, C, D and E slots of slightly different lengths. It currently is in the B slot on both wheels and I cannot seem to adjust it without a bow press because it is too tight.
I also don't want to mess it up or change something that I am not supposed to.

Does anyone know what this elusive pulley / wheel is for?

Thanks in advance.

I am not familiar with that bow.  If you show me a couple of pictures I can probably tell you.

Just an FYI. In case anyone else has this issue come up. I figured it out. Or actually Bear figured it out for me.
I emailed Bear customer support yesterday and they sent me a PDF brochure of my whitetail 2. It was in production from 1990 to 1995.
The pulleys in question are called "Easy tune yoke Adjusters". They are for making minute adjustments to the draw length by repositioning the cable in the wheel slots to change draw up to 1/4 " at a time.

I would like to thank Bear customer service for their prompt support and all of you folks for helping me in the past on other questions.
