Error Code "E04 Unit is

What is e)4 all about? Check manual/web site for condition and attempt to resolve to rid the error code.

Step 1 Look at the camcorder's display to identify if it is in Safeguard Mode. If its display indicates an error number of E01 to E06, your camcorder is in Safeguard Mode.
Step 2 Disconnect your camcorder from its power source and remove its battery by sliding the latch forward and sliding the battery down while pulling it away from the camera's body. Wait at least two minutes before continuing.
Step 3 Remove the camera's cassette by pressing the "Eject" button, waiting for the cassette door to open, and lifting it out of the tape bay. This step is only necessary if the camera indicates the E03 or E04 error code or it tells you to eject and reinsert the tape.
Step 4 Replace the camera's battery, power connection and cassette, and turn the camera on.

Error codes are indication that camera will require service. E04 is the only error you might be able to clear by holding down the eject button when placing battery back on camera.

E04 - Battery in Safeguard mode.

The most common problem with this kind of model. there actually no fix for this problem. Unless of course your a jvc technician and can manage to open and clean all the sensor inside.

Have you tried to most popular solution for that.. tapping a little bit on the side of that camera. lol.

Look closely with the memory card, make sure it is inserted properly. push it a little more.

You may need to remove the battery from the battery pack and then reinsert again before turning it on. Doing it a few times may help solve the problem.

I do suggest you remove the battery when not in use. Leaving the battery inside is the usual cause for having the E04 when turning it on.

Hope this helps.

E04
remove and reattach battery,
Unit in safeguard mode.

Here is some information regarding the E04 error message from http://www.techlore.com/article/10974/JVC-Camcorder-Stuck-in-Safe-Mode/:

"JVC notes that you are also given a malfunction code when the unit is placed into safeguard. If it displays code 01, 02, or 06 you should remove
the battery and powersupply and wait for a while. Code 03 and 04 indicate that you should eject and reinsert the tape.

If neither of these solutions work, your only alternative is to bring it to a shop or send it to JVC for diagnosis or repair. Unfortunately, there is no other way to clear the condition."

This doesn't seem uncommon, and indicates a bad tape is loaded, or unfortunately, that the camcorder requires servicing.

Do a search of this problem and you will ind that every JVC owner is having the same problem. I finally got mine "reset" by powering the unit on in payback mode while holding down the "play" button. Then, turn it back off and power it on in the camera mode while holding down the "rec" button. This seems to have reset it and I've not had anymore issues SO FAR!
Good luck with it.

According to this, E04 denotes a problem with the recording media or the mechanical bits that deal with the tape. Hopefully trying another tape helps.

Put it on fire and buy some good camcoder<br />

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. 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
