    Question: I forgot my password, how do I change the security code?


    Answer:  The C1900 uses a link (LK3- Located top center of processor board) to bypass all security codes.

    1) Install the jumper in the lower position, and you can access your program. 

    2) Change your password (enter 0 for no password)

    3) Move jumper in the upper position to reinstate security feature.
