* My comments :

         DO NOT TRY THIS BY YOURSELF IF YOU DON'T FEEL CONFIDENT ABOUT
         USING A SOLDERING IRON ON SUCH A MINIATURIZED DEVICE !!!

         DON'T FORGET THAT, IF YOU FAIL, THE WARRANTY WILL BE VOID !!!

        Now, let's relax. From the programming procedure, it is obvious
        that you enter 7 sub-bands in the unit :

                8 to   49.995 MHz
               50 to  107.995 MHz
              108 to  169.995 MHz
              170 to  296.995 MHz
              297 to  600.000 MHz
              805 to 1109.995 MHz
             1110 to 1300.000 MHz

        These are the values for the AR-1000 as sold in France. The values
        may be different for the units sold in Northern America (there may
        be other gaps, especially for cellular phone frequencies).

        I don't know what the following parameters (561.225 and 251.575)
        mean. I guess they indicate which RF subcircuit, which step, and
        which modulation mode to use. Anyway, since the sub-bands limits
        appear so clearly, it might be fun to experiment. See what I mean ?

        But, if we are to experiment, let's make things easier. Instead of
        dismounting-soldering-programming-unsoldering-mounting the unit each
        time, let's solder a 5" piece of wrapping wire to point (A),
        a 5" piece of wrapping wire to point (B). Now we have 2 free ends :
        let's solder a microswitch to them. We can glue the microswitch at
        the bottom end of the unit, near the power supply board. Resetting
        the AR-1000 is now much simpler : just open the unit (4 screws),
        flip the switch, turn the unit on, reprogram it, turn it off, flip
        the switch back, close the unit.
