Notice that the Channel Display advances to the next Band Letter each time the pins of JP1 are shorted. Temporarily short the pins of JP1 on the Channel Board using another short wire. Using 2 short bare wires, jump the pins of JP2 and JP4 (JP1 & JP3 = OFF) Notice that the Channel Display now indicates a letter A through L instead of the Channel number.

Set the radio’s Band Selector to position A. Disconnect the wires from the power source after programming the unit to insure that the CPU (Computer) will reset properly. For instance, if you wanted Bands A and B to be setup to cover 25.165 - 26.055 MHz, Band C to be the CB Band 26.965 - 27.405 MHz, then Bands D, E, and F to cover 10 Meters at 28.315 - 29.655 MHz, the “Programming Mode” can be used to set this up.
