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.
