I have the PV-GS300 Digital Camcorder and I now get the following error. "Dew Detect"!!! What can I do?

Hi:
Here are the instructions from the manual:
"Dew Detect/Eject Tape
Condensation has occured. Take out the cassette and wait for a while. It takes some time until the cassette holder opens, but this is not a malfunction."
On page 72 of the manual it gives more detailed instructions. Go to panasonic.com, put pvgs300 in the search engine. When you get to the pvgs300 page, click on the "get support" tab. A downloadable pdf of the instruction manual is there.
Hope this helps.
