The green Lock LED on the front (DIGITAL STATE) will light up as soon as a word clock signal
is detected. To change to word clock as clock source, active clock mode AutoSync and switch
Pref. Sync Ref to Word Clock. The status display AutoSync Ref changes to Word as soon as a
valid signal is present at the BNC jack. This message has the same meaning as the green Lock
LED, but appears on the monitor, i.e. the user can check immediately whether a valid word
clock signal is present and is currently being used.
AutoSync Ref also displays the frequency (Freq.) of the reference signal, here the frequency of
the current word clock signal, measured by the hardware.
