While attempting to reset the FSS, I f-ed up the procedure and discovered something new on the display. Here's what I did:

1. turn the key on
2. press left **** twice
3. hold **** in while turning the key off
4. keep holding the left **** for about 30 seconds.

Here's what popped-up (bad ascii art):

Anyone have an idea what it is?
