I cant update firmware untill i have the scanner registration key, I cant register the scanner to get the registration key because I cant update the firmware to get the ESN checksum number needed to register the scanner because I need to update the firmware first. 😱Squelch/volume indicators were added in firmware 2.0

To me the registration serial#'s was likely so infinitesimal of the web page just seems no reason to remove it.
