No, actually there was a note about the 285HV on the chart. I noted it b/c my own 285 is the HV model. Here's what it said--the note, not the original chart:
"Alan Latafat Correa checked with Vivitar and they clarified: The 285HV has a voltage of 12V. The 285 has a voltage of 350V. Hope this helps you. (Thanks Alan!)"
In the past, I have used my own 285HV with a Canon ElanIIe a few times and did not have a problem. But according to the original chart, the plain 285 has a "your call" rating. So it would be important in buying a 285 to know whether one was getting a "285" or a "285HV." At least that's my own understanding from all of this.
