The factory number and serial number fields are not important, as in they are not used for anything nor are they unique between radios.

(don't press the B / E button) Now the set volume should remain after a power cycle. NB: You should also be able to do this using th...

The only difference between them is the name and images, otherwise they are exactly the same and will work with any of the mentioned radios.
