           IC 2400A CROSS BAND REPEATER OPERATION

1) put both bands in +ACI-VFO+ACI- mode
2) set up one band with repeater offset and tone (if needed)
3) set other band for simplex
4) turn off radio
5) get a Octopus to help you, with the power off, push and
   hold following buttons: MONI, MHZ, SET, +ACY- DOWN button on
   microphone, while holding all above, turn on power.

Note- for Icom 2500A substitute CALL button for SET in
      step 5.

              TO GET OUT OF REPEATER OPERATION:
With power on, push SET button and hit MHZ button

Note- Some rigs will have to have D9 diode cut on Logic
board, however, later rigs do not have this diode.

If above does not work, reset the CPU as per Operation Manual before
tearing in and looking for diode, I had to reset mine, and my 2400A serial+ACM-
02402 did not have the diode.
