as I remember it is one of the record modes. you can press a key to get the recorder in to punchin mode or incert mode. If I said it was the three key I would be lieing probably but the feature should be documented in the users guide. ----- Original Message ----- From: Phil Parr To: ptr1-users@xxxxxxxxxxxxx Sent: Thursday, March 31, 2011 1:33 PM Subject: Little problem. I have a couple of P T R 1 units that work fine for the most part. I use one every weekend but one has just been sitting for a while. I want to begin using it again but, if there is something on the card when I press record it says punch in. If I erase the card the first time it says record like normal. Every time after that when I hit record it does that punch in thing. I am thinking if I returned it to factory defaults maybe this would fix the problem. Any help would be appreciated, Phil Parr.
