Section VI
TECHNICAL MATTERS
Firmware Version
With the INOmini 639 powered-up, hold the knob down for
5 seconds or so. The menu screen you have been viewing
will be replaced by the
639 Firmware
screen. This shows
the firmware version installed in your unit. This is infor-
mation that may prove useful when communicating with the
factory. Push the knob again to return to the normal menu
sequence.
‘Under the Hood’
The INOmini 639 is compact and sophisticated, utilizing
mostly surface-mounted (SMD) components. Many of these
are application-specific and/or pre-programmed at the fac-
tory, but all of them are impossibly tiny. This makes servic-
ing the unit in the field a difficult proposition at best. For
these reasons, and also because of the small format of this
manual, we have elected to dispense with schematic dia-
grams, servicing instructions and a listing of component
parts.
Notwithstanding this decision, our policy has always been
one of ‘full disclosure.’ We feel that, unless we are doing
something nefarious (or acting in the interest of national
security!), there should never be a reason to hide infor-
mation from the user. With a clear conscience, and upon
request, we will cheerfully provide additional documenta-
tion and divulge all but the very darkest secrets concerning
any Inovonics product.
Because it is so small and lightweight, returning the Receiv-
er for factory servicing is an option that we encourage.
Inovonics has never considered factory repair charges a sig-
nificant source of revenue, and we are confident that you
will be truly astonished at our reasonable shop rates!
