John - Your critique seems misplaced. Per ISO 7000, Symbol 434 means "Caution." How it's used, whether as a road sign or as a means to get someone's attention directed to an instruction manual, is not described in ISO 7000 and must, therefore, be assumed for use at the standards committee's discretion. If there are no words to support a specific caution, where would one go to discover such a thing but he instructions?
I'm confident TC74 debated this into the ground, since the US has always preferred using words, rather than symbols, based on ANSI/NEMA Z535.4 (Product Safety Signs and Labels), ANSI/SAE J1500 (Operator Controls, Universal Symbols) for and other preexisting US national standards. There are those who12 still actively resist use of symbols in place of words. Regards, Peter L.
