TM721A.5
                      MARS/CAP MODIFICATION

The following will allow the TM-721A to transmit on the VHF band from
142.000 to 151.995mhz.  Specifications are guaranteed for the Amateur
bands only.

MODIFICATION PROCEDURE

1.  Disconnect the antenna, mic, and power cord.

2.  Remove the bottom cover from the transceiver (6 screws).

3.  Locate resistor R57 on Control Unit (X53-3130-00) (A/3).  The
    resistor can be seen by looking through the cutout of the chassis
    just behind the front panel.  Please note that R57 is on the bottom
    of the unit and should not be confused with R58 on the top of the unit.

4.  Using a sharp pair of wire cutters, cut the resistor lead.

5.  Reinstall the bottom cover.

6.  Reset the microprocessor by following the procedure on page 22
    of the instruction manual entitled MICROPROCESSOR INITIALIZATION.

        NOTE:  Performing the previous mod will automatically reset
        the processor.  At least it did when I performed the mod.
        You can determine that when you turn the unit on and
        have lost all your memory settings.

        NOTE:  Performing this mod does not give you the license to
        transmit in these newly acquired frequencies unless you
        have the permits.
