If there is a circle with a plus in it, it means the center is positive.
And the line in the circle means negative.
Think of the circle as representing one looking at the tip, and the sign in
the middle an expression of what the center is with regard to polarity.

Subject: RE: AC Adapter for V1 recorder?
Thanks, Linus and Dan, for your help. One more question. I've found,
in my box of AC adapters, a 9 volt, 600 MA unit that fits into the player I
have. How do I know whether this is centre positive or negative? When I have
someone look at it, they can't tell, saying that there is a -, then a circle
with a dot in it, then a + sign. I'm sure this can be interpreted, perhaps
by examining the shape of the design or something, to tell me whether the
centre is positive or negative, but don't know how to interpret it.
I've already plugged the player in (it's useless anyway), and it
says "charging battery". Does this mean the adapter is positive and safe to
use on the recorder? Would there be smoke if the wrong polarity was at play,
or some other obvious way to see that the charging circuit had blown?

Yes, it's the same connector.
