Yeah, that is the box i couldnt open. There was no number to provide you though for that box so i supplied the only one i could find on the box below it. I guess both boxes are indoors for me.
Anyway, the answer was that you just pull it really hard and it pops open. The Fios guy came out and just used force. I was worried about breaking something. I was a little upset because no one said i just needed to pull it.. and that was the answer.
The Fios tech who was great btw, said that even if i had yanked out the battery, it still would beep so i didnt feel that bad. It is older technology i guess. He put in a new power source. All is good now and no beeping!! status: RESOLVED.
