It isn't really activated. It just emits power, as even when Arachne had it in her web, monsters from Tartarus were still trying to get it. The statue however is supposed to have some kind of power that can help defeat the Gigantes, as well as bring peace to the Greek and Roman demigods. And they activate it by I thinking bringing it back to Greece and returning it to the Athena Parthenon.
