Tip - Fixing Squeal Issue - if necessary
A customer stated that when using the speaker/microphone with his handheld radio, the system squeals loudly every time he keys the microphone button on the microhpone. I found that the same thing happened with my A14 and HM-234. I called ICOM America technical support and received excellent support - as always. I set the side-tone to zero by depressing and holding the transmit button (on the radio or speaker/mic) and using the down-arrow on the radio to bump the side-tone to zero.  That worked for me.

If that doesn't work, he recommended turning-off the internal microphone - as described in the manual.  I didn't need to do that.  He also said that adjusting the internal microphone gain might also help.
