I've updated both the receiver and the HH. 2.04 and 2.11
Same issue. Not fixable. Even if I change the types of presets, or the Crypto Off to On and Off...
Maybe it is not a software issue. But I don't care anymore. I bought a new wireless mic, of a famous brand. No more 2.4 Ghz!
Honestly, I am quite disappointed. Lack of knowledge here. Too many people having the same issues, but the guy who mostly replies, who acts like some kind of a Guru, always acts like a surprised person... That's for each topic. His advice is always "Did you check the antennas, cables... RF2 to RF1..."
I mark this topic as solved, since the answer to the problem is at the music store!
