Procedure:

1. Detach the front panel from the main chassis.

2. Remove the bottom cover of the transceiver by removing the 4 screws on

   the bottom of the cover and loosening the 4 screws on the side of the

   unit.

3. Orient the radio so the bottom is up and the front panel area is near

   your chest. Near the front panel area you will find a large board, this

   is the control unit.

4. Remove the chip resistors "Y" noted in the diagram below, and reinstall

   them in position "Z" as shown.

5. Reinstall the bottom cover of the transceiver and reattach the front

   panel.

6. Reset the microprocessor. Press and hold the MR key while the power is

   switched on. Then release the MR key. This will erase all operator

   programmed data.

7. The frequency range after modification will be:



        28  Mhz Band:  RX:  18.0 thru  54.0 Mhz

                        TX:  26.0 thru  45.0 Mhz

        50  Mhz Band:  RX:  40.0 thru  90.0 Mhz

                        TX:  46.0 thru  76.0 Mhz

        144 Mhz Band:  TX: 136.0 thru 174.0 Mhz

        220 Mhz Band:  RX: 215.0 thru 260.0 Mhz

                        TX: 215.0 thru 235.0 Mhz

        440 Mhz Band:  TX: 410.0 thru 470.0 Mhz

        1.2 Ghz Band    RX/TX:1100.0 thru 1400.0 Mhz



        Please note that these are theoretical ranges only. Not

        all radios will be capable of tuning the entire range.
