In an exceptional case, it is not possible to return the recorder to the factory settings via the menu. Then you will need to perform a hard reset.
- Turn off the recorder.
- Remove the top cover from the recorder. To do this, unscrew 5 screws.
- Then you are looking for 2 connections on the motherboard; TP5 and TP6. In the picture below, you will find the connection in the red circle.
- These two connections must be connected to each other. For example, use an iron wire. If these two points are connected (see picture below), you will have to turn on the power of the recorder. You will hear the recorder beep twice. The recorder is now fully set to factory settings.
