Go to Ikelite web site. #'s prior to 2000 or so need an upgrade only avail from them. Really old ones can't be upgraded I believe, but there are lots of posts regarding this that are easy to understand, as is the info on the Ikelite site. Try the wetpixel search for the other posts.
yes i saw some of the postst, most of them are ones that have a higher serial then i have
what im trying to do is atleast use manual, to my understanding i should be able to use that still without upgrade
i tried emailing ikelite but they just responded with ship it so we can see it
if its to old of a serial why should i send it in? i told them the serial and i would hate to waste more money since i just spent alot on this set up
im hoping to find a way to use manual mode but have been unable to so far
