Can one of you good folks who uses these phones contact me offlist please? I just bought a pair for my wife's use, and I have no clue what I'm doing. I think both parts are charged, and when I slide what I think is the on/off switch on the headset, I get a low tone after about ten seconds or so. I'v scanned the manual, and learned a little, but obviously not enough. So, help will be much appreciated.
