Bc2000 (for the BCF2000 & BCR2000)

Just picked up a used BCR2000 to control an Akai Miniak and a Kurzweil PC361. So far so good! Hello NRPNs! :)

I noticed that when I twist a push encoder, which lights its LEDs, the push encoder to the left of it has a slight "ghosting" of its LEDs showing the same motion. Like there's some sort of cross-talk going on. And interestingly, twisting push encoder 1 shows the ghosting on push encoder 8. Is that explanation clear?

This does not happen with the regular encoders. The unit is fully functional.

Anybody seen this?

Thanks.

P.S. -- I tried searching subjects for the keywords 'LED', 'problem', and 'ghost' but didn't find any relevant threads.
