Dingbats

[bigmac25]

I have two more I need help with. The first is a SQUARE Box with what looks like the male sign, which is a circle with an arrow on top pointing up and right, there is another outside the box pointing down to the right. The second is three lines of b's which look like musical notes. Would appreciate any help. Many thanks bigmac.
