A top official from Venezuela's electoral council says the audit of the vote from last Sunday's presidential election is not about "revising" the outcome and has warned against "false expectations."
Council vice president Sandra Oblitas also said, however, that only the Supreme Court can change the outcome.
Her confusing appearance on Saturday suggested difficulties ahead for opposition candidate Henrique Capriles. He claims the election was stolen by Hugo Chavez's chosen successor, Nicolas Maduro.
An audit of the 46% of the vote not scrutinixed on election night is to begin next week. Official results gave Mr Maduro a 260,000-vote victory of 14.9 million votes cast.
Inaugurated on Friday, Maduro spent much of Saturday with the presidents of Nicaragua and Cuba.
He tweeted that he discussed plans for the nation's future with them.
