1- Take out battery and antenna. 2- Take out screws from the case 9 3 long & 2 short )
3- remove green component per drawing. 4- Reassemble the radio. 5- Reset the radio. ( Reset switch is located below the PTT Switch Check that you have the new frequencies then reassemble the radio. You can now program 130.00 MHz to 169.995 MHz 340.00 MHz to 379.995 MHz 420.00 MHz to 469.995 MHz 870.00 MHz to 899.995 MHz
Hallo everybody, To extend the frequency-range of the dj500e, just cut two risistors. The resistors are R61-R63. The european version has the risistors in the following position: BP1 and BPX. The open version needs no!! Resistors. So cut them off. They are located on the printboard with the speaker and microphone. If you have the diplay on the left, you will look on the board and see them in the upper right corner..... There are two resistors with the numbers 000 (zero zero zero) on it. Actually they are no resistors, just a wire, but in smd it looks like a resistor. so get them off the board and do a reset !!!! The reset is very important because otherwise you will not get the new freq-range.... You got it???? Hopefuly, if not, leave a msg in bbs DB0AHA.
