Hi- Recently, I've been getting the "bad ir link" error from firmdl3. I can't figure out what's wrong - I've tried new batteries, different lighting conditions, near/far mode, slow/fast. I hope I haven't fried my tower - could someone please tell me (...) (23 years ago, 2-Jun-01, to lugnet.robotics.rcx.legos)
