Resetting the Fairmate HP-2000
I'm currently having problems with my broadband ADSL connection and, as it uses frequencies in the KHz range, I dug out my scanner in order to monitor for interference - forgetting that I'd effectively "bricked" it many years ago.
A web search reveals that it's still a popular scanner in one or other of it's many guises and I decided I had nothing to lose by attempting to reset the CPU.
All references to resetting provide a warning that you follow the instructions at your own risk. Take Note!
To reset the Fairmate HP-2000, you need to solder a temporary jumper wire across two points on the CPU board. To get at this board, involves removing two others stacked on top, as follows.
Locate components R405 and D405 and solder a thin wire between them as shown here.
For a better drawing of the CPU board, see here: Javiation.co.uk
Replace any connectors you removed and replace the middle board. Resolder the black wire. Temporarily replace the top board. Resolder the brown wire.
Replace the batteries and switch on. The display will be blank because the radio now needs re-programming.
Enter the following keystrokes exactly as shown. [v] is the down arrow key. [prog] are keys. Initially, not all keystrokes will appear on the display but, as the programming progresses, the radio becomes more responsive.
Because there may be no "feedback" from the display, press each key deliberately and carefully.

Switch off. Remove the temporary wire and re-assemble the radio.
Initially, I was going to leave the termporary wire available for future use but eventually decided against it!
