been made to the module settings
database in RAM but it has not yet been
written to flash memory. This is not a fault
and the flash memory will be updated after
10 seconds of no audio setting changes
being made. Do not remove power from
the module while this indication is present

- the command message from
the router controller is corrupt or hasn’t
been received.
This communications error could be
caused by a hardware failure or incorrect
insertion. Check that the module is
inserted correctly.
If the “Local Error” LED is flashing at the
same time as the “Local Command OK”
LED is flashing it suggests a mismatch in
the configuration of the Nucleus controller.
Check the controller configuration.
