But the handling is a Sony device is actually really not worthy. Whenever you press a button it will beep rather loudly. This can not turn one. I have found nothing about this in the instructions. So it beeps up. That would also not sooo big problem if not regularly saying the timing would undo. I do not know why it does that. This happens when the batteries are full. Unfortunately, the device does not work without time setting. This leads to the following situation: You sit at the beginning of a lecture in an auditorium, unpacks the voice recorder and the time has reset. To set the time you have with the record buttons the year, select the month and day. For every time pressing a loud beeping. If you get just one would so disrupt the lecture, if not higher to adjust it. This is really annoying.
