I'm not Jeff, but it's real simple. Plug mic and phones into the rear 
panel connectors. Go into the menu, choose the rear panel mic, and turn 
on bias (tap 2 on the keypad, I think -- check the manual). That makes 
the mic work. Set mic gain to low -- the CM500 is a pretty "hot" mic.

You're going to want to turn the speaker on and off, so I assign that 
function to PF2 (long push of XIT). To do that, go into the menu, find 
the Speaker + Phones toggle, and push the XIT button.

For TXEQ, full cut of the three lowest frequency bands, then do some 
additional cut of the 4th band with someone listening to guide you as to 
how much.  BTW -- those settings are good for both K3 and KX3.

Another hint for the KX3. Because the KX3 is specifically designed for 
backpacking and minimal current drain, the speaker and headphone amp are 
not very powerful. We can make the best use of the available power by 
not wasting it on low frequency sounds. This means that setting the 
three lowest bands of RXEQ for maximum cut is a good idea, and will 
likely imcrease the headroom by a few dB.
