Hi, I just received my DR 10CS small recorder and managed to use it with lavalier mic Sennheiser ME-2. It worked fine for 2 short uses (weddings) but now, there is no audio coming through anymore. I tried using my ME-2 Lav mico n other equipment and it works, so it's not lav problem. I also tried setting Mic Bias off/on as it should require phantom power. I also tried all different settings but no audio is coming through anymore. I also tried alka and nimh batteries, but no help either. I also tried selecting models - all 4 - Sony, Senn, Ramsa and the 4th one (forgot which one). Can someone help me out? Am I missing something obvious? Firmware is 1.0080. Is there a newer update?
