Even if there was a manual, the darn things keep changing and every unit has it's own set of quirks! =) Sometimes it feels like there is no quality control. You would think that by now someone would require a mandatory recall program, but it hasn't happen yet... I only have one, but I have heard that a second one could be a hit or miss. In some cases, it will help fix the first one, but in other cases it has resulted in getting spoiled itself.
