I had the same problem. I hope you have a battery charger. The many older batteries I have needed charging, but they wouldn't hold a charge when I tried to charge them with the battery charger. My batteries were the kind that had a memory, and I guess that the battery memories are dead. So, I saw that I had a double ended power cord that came with my camera. I took the battery out of the camera and saw a power-in hole. I just tried connecting the double ended power cord to the camera and to a power hole I found on the battery charger. It worked and gave power to the camera. It did not explode. I could not find a manual on any of the many websites
. I think that the camera I bought (Panasonic Palmcorder IQ PV-IQ403) doesn't exist in the available manuals. Maybe you can find a double ended power cord and a battery charger on line or in a store.
The following information might be useful to others. The camera cassette door will not open without having the power on to the camera. The camera connects to a TV
with RCA cords.
My camera power switch has 2 settings. Use the camera setting to use the camera to record and see what you are recording displayed on the TV. You must change the power switch to the VCR setting in order to play back the recording and see it on the TV. Change the switch back again to use the camera. (You can also see the playback through the viewfinder.)
My camera has a remote control which is stored in a slot. I found that the battery is in a tiny sliding door. I had to use a screwdriver to gently dislodge it from the case, my fingernail was not strong enough. The movable tab had to be pushed inward to release the catch. The coin battery was not corroded.

In order to play a VHS-C tape, you must have a VHS PlayPak. The cassette door will not open unless you have a battery loaded into the cassette. When the door opens, you can insert the VHS-C tape into the opening. The VHS PlayPak holder is the same size as a regular VHS tape. It can be found on-line.
