UNLOCKED STATUS
The display format for this type of error is as follows:
ERRnn UNLOCKED STATUS: XXYY (CC...CC)
When this type of errors occur, the MO-180 presents an error message on the
LCD display starting with the word STATUS and followed by an explanation of the type
of error. Under these circumstances, the ERROR LED flashes red for 5 seconds, and
then stays lit until Clear Errors under the STATUS menu is set to YES.
This type of error either indicates problems with some of the circuitry
implementing the modulation process or synchronisation errors with the different input
signals.

10 MHz sync loss.
In master MFN and SFN modes this bit flags a
loss of synchronisation with the 10 MHz
internal or external clock reference signal. In
automatic switch-over modes 1 and 2, once a
1
loss of sync with the external 10 MHz clock
source has occurred, this bit will not be set
back to 0 until the user reselects the 10 MHz
sync mode.
ACTION: Check that the selected 10 MHz
clock is working properly.
