Close UP Photo of The VX-7R's Modification Solder Jumper Area
Notice the 1,2,3,4,5,6,7,8 printed on the circuit board. The solder jumpers (solder blob) are right below the 1-8 printed on the circuit board.  To modify your radio, just use some solder wick (available at Radio Shack) to either remove the solder from pad 4 or pad 5.  Notice solder pads 4 & 5 are still intact - this is the factory (unmodified) USA configuration for the VX-7R.

Also notice the 4 unmarked solder pads in the right upper corner of the modification area.  At this time, the function of these connection is unknown.
