Cleaning the 4 mm DAT Drive
To clean a 4 mm DAT drive:
1. Insert the cleaning kit into the drive. The drive automatically detects
that the cassette is a cleaning cassette, then loads and runs the cassette.
After about 10 to 15 seconds, the cleaning is complete and the drive
ejects the cassette.
2. Remove the cleaning cassette from the drive and make a note, either in
a log book or on the cassette itself, that you used the cleaning kit.
Front Panel Lights
The 4 mm drive has two LEDs, one green and one yellow, that indicate the
status of the unit (see Table B-1).

Yellow Flashing Rapidly A hardware fault occurred or condensation was
detected in the unit (error).
Green On (lit) A cassette is loaded in the drive and it does not generate
excess errors (beyond a predefined error threshold):

(warning: heads may need cleaning).
