If one (or both) of these two lines is not present, or the HW version is reported as 1.0, or the
serial number reported is
“XXXXXXXXXXXXXXXX” (literally sixteen X characters), the
module cannot be field upgraded from the FRS-HD-CHO to the FRS-HD-CHO-ASI version.
Of course, the module can still be upgraded with the latest firmware and continue to work as
an FRS-HD-CHO.
