Find out what to do in Guest Room 3 in Resident Evil: Revelations, including Parker's puzzle and what to scan.

Parker will mention that Guest Room 3 is the room he was previously stuck in. He solved a panel circuit puzzle (a type of puzzle involving electrical connections) to escape. The only interactive element in this room is to scan the area below the bed. The bathroom contains nothing of note. After scanning, step back into the hall and reenter the Second Library area.
