I have a very similar problem with my JVC GR-DVL109. I put the tape in and the heads (I presume its the heads) make a very unusual high pitched whiney noise which lasts a couple of seconds. I get the error message E04 - Unit In Safeguard Mode. And sometimes "Remove and Reattach Battery" - even when the camera is on mains power. If I take the casette out - I can put the cam onto record mode and get images fine, but obviously no tape so I can't record. I can't play back any tapes either - I've tried with 4 different ones. Do I need to get my camera seen to? If so where is the best/most reasonable place to take it, I'm based in the UK.

I haver exactly the same problem than everyone with my JVC DVX44. It accepts to record , with a few messages "Remove and Reattach Battery", but when I want to see what I have recorded, IMPOSSIBLE. I cannot rewind the tape. Each time it begins to rewind but immediately the E03 error message appears. I can eject the tape but each time the tape is eaten a bit more and 10cm of tape remain out of the cassette. Any comments? I of course tried to gently tap the camera, I blowed the mechanism, and used a cleaning tape. I use JVC tapes. What to do but bring the camcorder to JVC, what I certainly won't do in view of the comments I have seen.

I had exactly the same problem on my JVC GR-DVL100. E04 , Just when my daughter were singing on stage the error pops up, and no joy. Up til now I could still run it from the mains connecter. JVC are BASTARDS

PROBLEM SOLVE!! Most of the camcorders all have the same problem. The most common problem is within the tape ejection mechanism. Since there's many moving gears and parts; a small particle of dirt could easily cause it to jammed up. If you getting an ERROR(ERROR message is part of the safety program incorporated in the system to protect the tape against accidental deletion) message regarding system safequard while the tape in in the unit, don't sweat. In order to clear the message, you need to REMOVE THE TAPE AND RE-INSERT IT BACK IN. A typical method of doing so is to press the EJECT button. If that doesn't work, use compress air to blow out the dirt in the moving gear or track. If all other fail, use a small(flat head) screw driver or paper clip to help open the tape housing unit right after you press the EJECT button. After you get the tape out, then remove the battery, and re-install the battery and then the tape back in the unit. That should reset the system safeguard program back to normal.

I have a JVC 70 US brand new that I used for maybe 3 hours in total. Since then i started getting E04/E03... remove this... remove that ...and so one. I am so upset. I think that JVC should withdraw all their Camcoders from the market. JVC is a mess. I spent my money for shit ! And the way JVC keeps quiet and not provide with solutions is very surprising ! Like they don't CARE. I would say no more JVC AT ALL. DON'T BUY JVC. Please Boycott JVC till they take good care of their customers.

Can anyone help me out?? I have the JVC GR-DVL300 but I can't find my software anywhere.. Does any one know if and where I can download the software??? Please help me out guys. Just reply to my email address douglas.e.goodman@wellsfargo.com Thank a lot

I believe the error codes are a polite way of jvc saying, "this cam is eating your tape." I thought I'd be clever with a nice transition of sending the cam down a slide with my daughter, but the ride apparently jarred the gr-dvl300 enough to eat the tape. From there I got the error message saying to remove the battery, E06, I believe. So, removing the tape, and either being able to rewind the eaten tape back into it's casing and reinserting or inserting a new tape fixed mine from the safe mode error code. -sean
