The SGC-2000 IS Type Accepted and therefor can be used legally in both
the Marine and Ham Radio Services, as long as it is UNMODIFIED from the
original factory configuration.

Any other Marine Radio that is Type Accepted can be used in Marine or
Ham Radio Service, as long as it is UNMODIFIED from it's original factory
configuration.

If a Marine Radio that is Type Accepted is then subsequently MODIFIED
by anyone other than the OEM, it is NOT considered Type Accepted any
longer, by the FCC, as it is now MODIFIED, and therefor must go thru
the Type Acceptance Procedure again to qualify for Type Acceptance.

Any MODIFICATION to the radio that changes it's basic configuration
or Operating Charactoristics would invalidate the Type Acceptance for
that radio.

"Opening" a radio is considered such a MODIFACTION, as it requires one
to actually take the covers off and change something mechanically inside
the radio, itself, thus altering the FACTORY OEM Configuration.

Not all that clear. The ICOM M-710 is "opened" by uploading software
mods. Are you saying that if these mods are uploaded by the factory
or a dealer then it is still Type Accepted, but if I do it myself then it is
not?

BTW, your shift key seems to be malfunctioning. Better have it checked
by a qualified technician
