suunto zoop novo question

[inverse_suit]

I think that on a dive I saw a sign on my Novo that I didn‘t find in the manual. It was in Dive Mode (Air) and appeared on the right hand side, where for example the time for the safety stop is shown. It looked like kind of a „7“. One long bar and one at the top going from the right to the left. Something like that (but the lines came together, no space in the top right corner):

Does anyone know what that is?

Is it what is shown near the top of page 18 of the manual?

No, no letters. Maybe I was dreaming…
There weren‘t any time indications, so it certainly wasn‘t something about decompression floor/ceiling/… The dive itself was by far none that required deco-stops. Max depth of 13 meters, 55 minutes total dive time.
Thanks anyway! Maybe I don‘t remember it right
