Hugh Holesome Posted May 17, 2011 Report Share Posted May 17, 2011 It was working fine and then died in the middle of a shot. Obviously thought it was the battery and tried a few of them but the unit doesn't even power up. Anyone have this happen or any ideas how to get it in use again in the field??

Obviously thought it was the battery and tried a few of them but the unit doesn't even power up. Anyone have this happen or any ideas how to get it in use again in the field?? Sometimes the positive and negative battery springs in the UM gets bent back to far and can't make the proper connection to the battery. Try sticking a couple of strips of mole skin to the back end of the nine volt for a sure battery connection. See if that works if not send it out for repair. Good Luck.

Richard Nault Posted May 18, 2011 Report Share Posted May 18, 2011 I second Neil's response... had some intermittent troubles with a UM400a a few months back and sent it back to Lectro for repair. Turns out it was the battery spring. Cheers, Rich Quote Link to comment Share on other sites More sharing options...

LarryF Posted May 18, 2011 Report Share Posted May 18, 2011 The springs are photo etched from stainless steel sheet. The sheets are made by rolling the steel to be thinner and thinner. The direction of the stretching means the metal flows and has a grain direction. This causes the metal to bend easier in one direction than the other. If you form the springs at right angles to the correct direction, the spring bends easily and takes a set. After we have it gold plated, it is hard to see the incorrect grain direction. The fix is to replace the spring. This comes under the usual "We blew it" warranty.

LarryF Posted May 18, 2011 Report Share Posted May 18, 2011 Just a follow up on the previuos posting: Dean in service said, " We don’t normally see the UM400 have battery contact problems that prevent operation. UH400, UCR190, CR187 all had contacts that would bend to the point of not working but not the UM. More likely, in this case, that the processor clock crystal is bad (for whatever reason). Just a guess though, number of issues that could cause this symptom." Best, Larry F Lectro Quote Link to comment Share on other sites More sharing options...
Hugh Holesome Posted May 19, 2011 Author Report Share Posted May 19, 2011 Thanks to all who replied and even when manually holding the battery tight the unit was not "feeling" power. The production is facilitating the Lectro service repair. I was hoping it was somehow operator error to get me through the last few days of shooting. Thanks go to Jeff, I do appreciate this community! Hugh Holesome Mic On A Stick Quote Link to comment Share on other sites More sharing options...
