mars/cap or freeband modification for 3rd generation vx-5r's
1) remove battery
2) remove the sticker/cover for the pressure sensing unit (su-1)
3) remove the su-1 pressure sensing unit option board (if installed)
4) factory configuration for usa vx-5r usually looks like x x x o o x x x (x = no solder ball o = solder ball)
5) for mars/cap, remove the 4th solder ball and solder a ball on the 6th jumper (see note below) - your jumpers should look like this x x x x o o x x
6) for freeband, remove the 4th & 5th solder balls and solder a ball on the 6th jumper - your jumpers should look like this x x x x x o x x
7) reassemble radio and reset the radio (pwr-mr-vfo-4) - you will loose all stored memory channels and custom settings and the radio is now modified
specific information on all 8 solder jumpers can be found here.
