							AUTO OFF error messages
If a problem has occurred and the VTR cannot continue operating or the mechanism or tape may be damaged
by continued operation, the AUTO OFF lamp on the VTR’s front panel come on, the buzzer sounds, and an
error message appears on the screen. In this situation, stop operating the VTR, and proceed to fix the problem.
≥With the exception of the DEW error message, the original screen will not be restored unless the power is
turned off and then back on again.
≥If the error persists even after the power has been turned off and then back on again, the problem is serious,
and the VTR will need to be repaired or some of its parts replaced. Immediately turn off the power, remove
the power plug from the power outlet, and contact your dealer. Bear in mind that continued operation may
exacerbate the existing problem and/or cause other unforeseen problems.
AUTO OFF lamp
AUTO OFF occurs mainly when the tape transport system is experiencing problems.
When AUTO OFF has occurred, open the VTR’s top panel, check that the tape in use has been proper-
ly installed in the transport system, and then turn on the power. If the tape in use has become disen-
gaged from the transport system, contact your dealer.

							SYSTEM error messages
When a problem has occurred in the VTR and its operation can no longer be guaranteed, the system error
lamp comes on, the buzzer sounds, and an error message appears on the screen.
In this situation, stop operating the VTR immediately, and proceed to fix the trouble.
≥With system errors, the original screen will be restored when the power  switch is turned off and the cause of
the error is eliminated.
