Hmm, bit of a problem here, and I'm not sure what to do about it! The LOW pulse key appears to have bust. It's been a bit iffy since I bought the Fluke, and now it's completely stuck "on" or "in", whichever you prefer... So, - Anyone have a known source for individual replacement keys? - If not, anyone have a replacement keyboard to part out? - In the meantime can I happily use the rest of the system with the low pulse stuck on? - If not, can I safely just wire a switch to the two pins on the back of the key? (not desperately a great solution, but a solution I guess!) - Anyway to actually get this key to release and thus fix it? (I can't see one) Note that this is one of the toggle keys, ie, it's meant to stay in or out, but it's stuck completely at the moment :O( Thanks for any help, Martin. ------------------------ Guddler's Arcade http://www.guddler.co.uk
