If you enter a wrong password for the service menu the analyzer just does nothing.
It doesn't display a message like key invalid.
I guess this string is used for the option licensing maybe?

Pressing SHIFT + TRANSIENT will also ask for a password. 882323 will not work. any clues what this password is?

Thanks

I also have this model analyzer.  Documentation says they offered an "Option 5" Audio Demodulation.  I wondered if it was just enabled through software or if it included some hardware.  I had the front panel off a few days ago, and found the internal speaker is there, along with the headphone jack, and everything is wired up and therefore I think it is just a software option.
