E04 Unit in safeguard mode : Remove and Reattach Battery
I have had this same problem since my warranty ran out on my JVC DV camcorder. When I turn it on to record or play, a code appears on the display screen "E04 Remove and reattach battery. Unit in safegaurd mode." I have tried to remove the battery and replace it and I have the head cleaned. Twice I have brought it in for repairs but over time the same thing comes up. Can any one tell me what causes this and how to rectify it.

I've been given a GR-DVL-367EK camcorder which is completely inactive except for error code E04. Cassette has been removed but the cassette holder doesn't open.
Heard there is a software fix for this problem - does anybody know where I can find it?

OH, MY GOD! WHAT IS GOING ON WITH THIS CAMERA. DO WE NEED JVC TO REPLACE THEM. WHO KNOWS MAYBE THEY'RE RECALLED OR SOMETHING. THE E04 ERROR HAPPENED TO US. WE WERE RECORDING AT OUR DAUGHTERS CHEERLEADING COMPETITION. WHEN IT WAS THEIR TURN. NOTHING. IT COMPLETELY GOES OUT. AND MY KIDS WERE ONLY 5 AND 6. I WAS SO MAD, THAT I WAS UNABLE TO GET THEM ON TAPE. SOMEBODY LET ME KNOW IF THERES A REAL WAY TO FIX THIS PROBLEM.

I just came back from vacation and was totally unable to use my camcorder because of the same error message. I'm so frustrated. Have you been able to get yours fixed or find out why this happened?

I am using a GR-DVL-100 now for three years. I had no problems untill (I suspect) that I attached a Hahnel Lithium Ion battery (HL-408). Since I used this battery (as second battery device) problems started. Maybe it is coinsedence I do not know. It is good to know that more people have problems. I'll ask my lawyer if they come up with repair charges!
Best regards,
Perry

I have had my JVC GR-DVM for about 5 years and about 9 months ago after not having used the camcorder for about 9 months I started with the same problem described by all. I have cleaned the contacts for the battery and the those on the camera. I have also tried the AC adapter and still the same safe mode message

I have two JVC DV camcorders. Two different models, both coming up with the same "E04" error. Just wondering if you came up with a solution. I am frustrated to no end. I would appreciate any help. Thanks, Jack.

Here's what i found. I was able to clear the message by opening and closing and ejecting the cassette. I also had to play with the battery at the same time. Keeping the cassette door open and then pulling out the battery. After is did this a couple of times i got the message to clear. I too haven't used my camcorder for some time and now that the error message has cleared the camcorder tells me that i need to clean the heads.
Hope this helps. Below is the message i found that pointed me toward ejecting the cassette.
Good Luck, i'm off to buy a tape head cleaning cassette.
An error indication (E03 or E04) appears.
- (E03 or E04 UNIT IN SAFEGUARD MODE REMOVE AND REATTACH BATTERY) This massage a malfunction
of some kind has occurred.
In this case the camcorder's functions become unusable.
- Eject the cassette once and re-insert it, then check if the indication clears. When it does, you can resume using the camcorder. If the indication remains, consult your nearest JVC dealer or service center

This worked! Thanks a bunch. We missed 6 months of our kids' life on tape due to this malfunction. Call it laziness, I know, but now the jvc works and we'll miss no more!
Much appreciated.

It worked for me also. I bought a new battery, and got the same message. Ejecting the tape reveled it had looped up a little. I had to remove the battery before it would allow the tape to be re-inserted, but it worked. Thanks for the heads up!

Yeah, I have seen this problem 2 weeks ago after not using my GR-DVL100 for several months. The unit is about 5 years old. After I read comments on the topic, I went to buy the head cleaner. The problems seems to come on and off, but haven't given up trying. At least, the picture now show but with no sound, and at a bit faster speed. Look forward to see the end results

To Steve and others - I tried Steve's suggestion and it worked. It appears that the tape I was using may have created a jam in the camcorder. I took the tape out and opened and closed the tape compartment several times before putting the tape back in. The Safeguard message went away and the camera appears to be working fine, Before trying this I was ready to scrap the JCV camera and go buy a SONY. Thanks for the Tip!!!

I have a JVC GR-DVL805U. My E04 UNIT IN SAFEGUARD MODE REMOVE AND REATTACH BATTERY message seems to have been caused by a broken tape. I pushed the tape cover release latch and after lifting the casset cover I discovered that the tape was broken. The message has not appeared since inserting a new tape or replaying old ones. However, only time will tell if this was the real cause. What caused the tape to break? I don't have a clue.

Steve,
You saved me $250. That's what an electronic retailer told me JVC charged just to diagnose the problem. I followed your instructions and it worked.
THANKS!

i tried doing what you said but the casset thing wouldn't open so i did something that you probably shouldnt do....i smacked the camera and what do ya know it opened and the message went away :D
- Re: E04 Unit in safeguard mode Summit Raj Tuladhar - 11th Oct 2005 7:25
JVC GR-DVL100. Same Problem E04 "Unit in safeguard mode". Ejected the cassette and just when it was about to eject, pushed it in... and the error is gone. Thanks!!
- Re[2]: E04 Unit in safeguard mode Rubens Ramos - 31st Mar 2007 12:00
It's worked to me too - the procedure is: just open the cassette cover, eject the tape and right the way push it back again. I've done this 3 to 4 times and... done. I've also used a head cleaner cassette before doing it (the head cleaner cassette alone have not fixed the problem). It appears to be some kind of hard reset. Thanks.

I just fired up my camcorder (DVM80) for the first time in a couple years and got this message. The battery coming in and out didn't do anything. Popped the tape out and found that it was being eaten by the camcorder. Wound it back in and tried to rewind. E04! Wound the tape again and tried to play. E04!
Fast forward worked just fine, but rewind got the message again when it hit that spot on the tape. Wound it back, forwarded to the end and rewound, E04 at the same spot. Wound the tape in the rewind direction, pulled some extra out, and rewound that, and after that I could rewind the tape to the beginnig and view/record, so I think the message is less a battery problem than it is a tape problem

Try Steves solution guys..it just worked for me just before I went on vacation.
Phew thought I would have to buy a new camera.All I did was install the tape and try and play it without closing the cover.It ejected on me twice when I did it the 3rd time I closed the cover and it works fine now.
Yeah Steve thanks for the information and I did need to get a head cleaner
- Re: E04 Unit in safeguard mode Taylor - 5th Feb 2007 20:15
I tried using my head cleaning tape. But the error pops up when I put it in, and wont let me play it :/.

Izaurek - 11th Dec 2007 18:22
You must make a hard reset - get inside the camera and unplug the buttery - in jvc grd30 it is done when you take out a plug with many wires
wait a couple of minutes an plug it again
Now it works:)
- Re: E04 Unit in safeguard mode Taylor - 5th Feb 2007 20:34
ALSO, it's only doing this with one tape. My other older tapes work, but this one is brand new, and not taped over..

Yang Nguyen - 8th Sep 2007 5:18
That's right. I have the same messages with my JVC as well. I left it unused for 1 year. When I started using it, I've got the error.
The problem is really about the lens being dirty and moister.
Try to clean with alcohol is the best.
AFter cleaning I even used the hair dryer to make sure no moister is remained.
It is working now.
- Re: JVC GR - DVL300 - 2nd Jun 2004 2:09
wow...it really helped to read these emails...I reset the battery in manual mode and taped a few times on inside with viewer open. It started working again. Isn't this an expensive camera to have this problem sooo fast...mine is only 2 months old :(
- Re: JVC GR - DVL300 Tash - 5th Jun 2004 7:26

I THOUGHT JVC WAS THE BEST NOW I HAVE NO CONFIDENCE IN ANYTHING THEY MAKE THANKS JVC FOR MY 30 TAPES, THAT ADDED UP WITH THE PRICE OF VHSC BLANK TAPES AND THIS PIECE OF CRAP CAMCORDER/PAPERWEIGHT COST ME ABOUT $800.

I have the same error message but the code is E03. After seeing this thread, I will never buy another JVC product again. I am also very disappointed at Best Buy for selling a unit with known defects.
