Hmm, I'm not sure how far the range goes, but you can bring your pokémon out to where you are.

[She lifts up her band, showing... something that indicates about pokémon ok.]

We can't walk around with them everywhere, and not everybody can keep their pokémon at home... so we keep pokémon in the habitat. You can have some ready to be called up before you leave, so when you need them...

[She shifts the squirtle in her arm, bringing attention to her.]

Ta-da.
