Command Description

02ERROR: Returned when the VCR receives an invalid command after the second byte of the transmitted command. In this case, even though commands are sent continuously, no commands can be accepted except STATUS SENSE. To release this error mode, send the following commands.

41CLEAR ERROR: Clears the last transmitted byte. Use this to release the error mode as well.

56CLEAR: All commands are canceled. This is also used to release the error mode.

0B	NAK: Returned when the VCR receives
	an undefined command for the first byte
	or a command specifying a function not
	available on the VCR. Releasing the
	error mode with the CLEAR command is
	not necessary. Just send a correct
	command.

*Usage example of CLEAR ERROR Specify the cue-up point at 1:10:10:25.

As this data cannot be specified for the data following the

CUE UP WITH DATA, correct the data.
