Late last night I noticed that the red recording light was on despite the fact that the last recording had finished over 2 hours previously. I had already checked that that recording had been successfully completed and I definitely noticed that the red light had gone off. I then checked the planner and there was nothing showing as being recorded. I turned the box off at the mains and waited a couple of minutes before powering on again. The red light came on again, with nothing showing in the planner as being recorded. As a last resort I unplugged the box again and left it like that overnight. Touch wood it seems ok after swictching it back on today. Anyone had any similar problem? I assume if I had left it with the red light on then the constant "recording" would have eventually wiped out everything stored in the planner.
