Do you have to say anything to activate a NerveGear?


I was wondering if you had to say anything to activate a NerveGear. I remember
Kirito saying something before he went into the SAO world but I can't remember
what. I thought he might have said something to activate the NerveGear, but I
don't know if he actually did or if my memory is playing tricks on me. Can
someone please help me figure this out?




> To use the NerveGear, the player wears the game console over the head. Then

> the body, commonly a bed. Afterwards, **the game will load upon utterance of
> the initiation words, "Link Start".**

(Emphasis mine)
