Budweiser Red Light - 2 questions

1) I see discussion here about removing the imp -- how do you remove it and where is it? I don't see anything removable other than the battery cover.

2) It worked for last night's game, but it seems that after it goes to sleep it doesn't come back on again when I "test" it using the app. Hitting "test" in the app does nothing. Will it still wake itself up 5 min. before the next game?

Thanks.
