When I mention the remote I am referring to the remote that came with the DVD recorder, not the TV remote.
After selecting a recording duration with the REC button the recording length will show on the TV screen for a couple of seconds. Beyond that I believe different models have different methods of displaying the “remaining recording time.” Some may show a “countdown” on the machine’s display. Try pressing the STATUS button twice. That may cause that information to appear on the TV screen until the next press of the STATUS button.
It’s been a while since I’ve used the manual recording feature. I have Panasonics of the 2005, 2006, 2007 and 2008 model years so it’s sometimes difficult to recall the variations between my Panasonics. Among my Panasonics I have two different models from both the 2005 and 2006 model years but all the 2007s are of the same model. I have a single 2008 model.
