A:AnswerI see your problem. It looks like you can choose any sleep timer timeframe from 5 minutes to 240 minutes. But all you can do by choosing off is reset the sleep timer minutes setting what you had chosen. This could a glitch. It looks like you cannot turn sleep timer off, just reset it.
A:AnswerI also have trouble turning off sleep timer. Its set to 240 but turns off after 5 min on pause. No option to TURN OFF!! I really hate it and wish i returned it.
