Inside my new frig freezer there is a sticker.
It shows an arrow pointing down. Inside the arrow is a vertical
oblong.Beside the oblong is a small circle and below the oblong is a
larger circle.
Below the arrow is a large black spot and beside the spot is printed
X13. What does this mean?

Feck knows, but I expect its "obvious" when you know!

Post a direct link to a photo somewhere, doesn't google have a "find
similar images" thingy?
