	NOTE: Call for detailed chassis drawings before attempting to build a roadcase.
	write-in label - The white area at the bottom of each channel may be written on with a grease-marker, and later wiped clean
	with a cloth moistened with isopropyl/rubbing alcohol. Artist (Board) tape may also be applied to this surface, and the tape marked
	with a permanent marker. NOTE: Do not write directly on the Console’s surface with a permanent marker. Avoid using standard
p. 58	masking tape; it dries out and leaves a hard-to-remove glue residue.
