In the operating instructions for the AJ-HD1200A on page 53, it says:
“The unit comes with an auto head cleaning function which reduces the amount of dirt on the heads automatically. However, in order to improve the unit’s reliability, it is recommended that the video heads be cleaned on a daily basis. Use the cleaning fluids specified by Panasonic.”
This seems sensible and wise, as long as you are careful. I haven’t found anything yet on the Panasonic website that tells me which cleaning fluids are preferred. Is there a Panasonic rep out there that can comment on this recommendation further?
