"RECOVER" lights steadily. The Flexicart tries the self-recovery
operation.
When the cause of a fatal error is eliminated by the recovery
operation
"IN USE" lights steadily. The system can now be operated normally.
When the cause of an error cannot be eliminated by the
recovery operation
The error message indicating the cause blinks again. Repeat the previous
operation "To eliminate the cause of the error," check again, or contact
your Sony dealer.
When an error that is not fatal has occurred (the Flexicart continues
operating even after the error has occurred), a blinking message indicating
the cause (the most recent when a series of errors has occurred) of the error
appears.
Check the cause as follows.
1
Press the CONTROL key.
Each time you press the CONTROL key, blinking messages appear
one after another, indicating the cause of any errors that have occurred
in the operation of the Flexicart.
2
Press the CLEAR key to change the blinking error message to "IN
USE."
Note
The Flexicart will try to continue operating, but may not be able to operate
normally. For example, the overall system may be able to operate, but a
block of VTRs or block of bins where the error occurred may be disabled.
In such a case, consult your Sony dealer.
