I have a JVC GR DVL100 which worked until I used an old cassette which had jammed before. The unit went into safeguard mode E01-E06. We went through the rrror indications, turned off the camcorder, we removed the power supply and battery and waited gif the message to clear. We tried two other cassettes including the cassette cleaner and all three cassettes have jammed and ruined the cassettes. Do you have any suggestions on how we can prevent the cassettes being ruined in the camcorder. Thanks

I had this same problem, and indeed it was from leaving a tape in the camcorder while in storage. All I did was remove the tape and put a new one it. Solved my problem! Thank you!

There should be an error code star with E-01 to E-06.Below is an example you have to make sure that which error code showing on your camera
Whenever some abnormal signal is input to the syscon CPU,
an error number (E01, as an example) is displayed on the
LCD monitor or (in the electronic view finder).
In every error status, such the message as shown below
E01 LOADING--------
1. The mechanism is locked during mode shift.
2. The mechanism is locked at the mechanism loading
end, because the encoder position is skipped during
mechanism mode shift.
3. No power is supplied to the loading MDA

I found the solution on another web site. You just eject the tape, and then give the camera a few sound whacks near the microphone (I tapped mine of a carpetted floor). Believe it or not this seems to work! My camera had been in "safe mode" for over a year without any success in fixing it. I tried the above method having lost all hope of ever using it again, and presto, the think came back to life! Can't say how long it will last, but at least it's out of safe mode;-)
