[ICOM] ICOM IC706MKII WON'T TALK TO MY ICOM AT-120 AUTOTUNER!

[XE1UFO]

Dear Friends,

First of all, I must say that I am learning a lot from this list!
Thanks, everybody!

I have an Icom IC-M700 marine SSB rig that I have been
using on the ham bands without problems.  This unit came 
with an Icom AT-120 automatic antenna tuner, and works 
just fine with the M700.  I can tune my 80-meter doublet
(fed with 450-ohm ladder line) on all bands from 160 
through 15 meters.  (The M-700 does not work above 
23.999 Mhz.)

Yesterday was our annual ham radio luncheon and flea market.
I managed to give up my beloved MFJ-269 antenna analyzer 
and some other things and come home with an almost new 
Icom IC-706-MK-II-G. So, Icom radio and Icom tuner, no 
problem.  WRONG!  Pressing the Tune button on the rig 
does nothing.  And I opened the lid on the tuner, and it has 
a gazillion dip switches and a toggle switch. Try the toggle 
switch, and still nothing happens.  I am not brave enough to 
try the dips, without somebody holding my hand.  HELP!!!

Does the tuner resent being separated from the M-700?

Thanks in advance!!
