Re: E04 Unit in safeguard mode
- 11th Feb 2005 2:06
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
