Make that "at least five times":

ghIq jach qa'rol
    maQ 'oH
    HemHa'choH 'ej cho'choH moratlh
Then the qa'rol raises voice
    The signal for Morath
    To lose his pride and claim a throne.

(paq'batlh, book paq'yav, Canto 5, lines 10-12)

maQ 'oH is a different sort of example, because it uses a pronoun-as-copula instead of a pronomial prefix, but it's another example of a previous statement (jach qa'rol) being referred to in the subject as "it". From context, it seems clear that the signal is the qa'rol crying out, rather than just the qa'rol itself, so 'oH must be referring to the whole act and not merely qa'rol.
