20 Most Recent Sennheiser EW100ENG-G2 2-Way Radio Questions & Answers

If you use a sennheiser check your Squelch is not set to high / low. I use a Z1 and that solved my problem.

Even if you can find a schematic, it's not going to help you. Changing a radio's operating frequency by almost 30% requires changing a fair number of parts. You'd have to know which ones and what the new values would need to be. Then the radios would need retuning and adjustment, which requires test equipment you aren't likely to have. Their operation would might also be unreliable as well, and this could be a problem if these are used in performances. Then the radios would no longer even be legal, since their governmental approval is based on their operation at the original design frequency. You could be liable for fines if you're ever identified as the source of interference to other radios with the modified equipment.

In short, you'd be better off buying new radios already in the range you need than trying to change these.

Thanks for using Fixya!

You have to wire the plug to eliminate the voltage sent by the sound card. I can't remember if it's the tip or the sleeve, so you'll have to verify with a volt meter. Use a 3 position plug to solder to the mic wires, just don't connect the wires of the mic to the one that has voltage on it

Yes I had the same problem. Under some circumstances the MM100 freezes (didn't figure out when just yet). It's a software issue inside. Solution: open left speaker (the side with the charge connector and hence the battery). Discharge the battery (or just short circuit for half a second) and it works again. Sennheiser should built a reset button on these things.
