• If you have any problems using this product, this manual will surely help you.
In order to detect the cause of marine accident, the VDR records hull data and navigation data.
If an accident has occurred, it is mandatory to preserve the record data immediately.
In case an accident has occurred, please preserve the record data according to the procedure
described in 1.4.4: "Actions to be taken at the time of an accident"
To ensure the proper operation, we recommend you to read the procedure carefully.
ATTENTION
VDR erases older data that has passed for more than 12 hours and
overwrites the new.
Therefore if you do not operate properly, the recorded data at the time of
accident will be erased automatically after 12 hours.
