Unitrunker should be able to turn it on when it needs it. The option to turn in on in the radio may be found but Pressing PGM, FUNC, F3 (GLOB) and scrolling down to the bottom of that menu. The best way to get to the bottom of the list is to press the FUNC key, and then the Down Arrow.
Excuse my ignorance of this scanner(new owner still learning). What is the purpose of the CCdump and what can I use it for? I was able to bring it up in Win500.
