Re[2]: E04 Unit in safeguard mode

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.
