this, press the Offset button, which will display the following dialog:

this happens.
The main master clock dialog has a drop down list labelled "Sync Source". This
allows you to choose between Master, Learned and Word clock modes of
operation. In Master mode, the unit uses its internal calibrated TCXOs. In
Learn mode, the unit slaves to its input, but remembers where it was if the input
