USB FULL is displayed, and the MASTER REC button is rapidly blinking.

This error is displayed when recording or MEMORY CUE/HOT CUE REC is performed when there is no free space on the USB device, and no recording is performed.

If the error is displayed during recording, the recording automatically stops and saves the recording results from before it was stopped.

The rapid blinking stops when the MASTER REC button is pressed again.
