Panel Produced Date

How do I find the produced date of my Pro Panel 1.9v.

It’s on a sticker on the back. Batch number is in YYMM format.

So my batch was 2406 . The board will not load. Power light is on and status is on. This was a gift from a friend so maybe you could identify when it was purchased. I have the old version but would love to upgrade my system. Thank You
