Help on diagnostic error in Lexicon DC-1 v. 2.1

Lexicon is a little slow in responding (as I said, they're average), but they have always responded to me. You might try calling them, or sending another email.

Sent an email already to Lexicon, but still have yet to receive a reply. Anyway, thanks again for your help.

It's been a while since I ran the diagnostic/reset procedure, but I don't recall any difficulty at all, and I simply had the instructions printed out in front of me - followed them to the letter. I don't recall having to wait too long though.

I suggest you send an email to Lexicon, or call their support line. Just spell out your problem and see if they can help. They're generally responsive (though not as much so as some companies I'm familiar with).

Thanks for the suggestion.

Tried the reset procedure thrice but was unable to get my unit to display "Extended Diagnostics Select A Test" despite pressing and holding on the required buttons for more or less 3 minutes. How long will I press and hold the buttons till the unit will display these words?

Reset the main program by the following procedure (I received it from Lixicon support:
