(provided the menu has been switched off).
key lock On: Key Lock enabled.
Off: Key Lock disabled.
intern On: genlock to internal reference selected.
LED lights up as well if genlock = seconds pulse is selected and the
generator currently stays in a coarse trim.
genlock Case genlock = video or black-burst selected at menu SET - .. - LOCK:
Lights up if genlock is operating normally. Flashes if the genlock signal
is disturbed and the internal reference is currently selected. If the
genlock signal returns to be ok the LED will light up again.
Case genlock = LTC input signal is selected at menu SET - .. - LOCK:
Lights up if genlock is operating normally. Flashes if the genlock signal
is disturbed or the frequency of the LTC input signal is beyond the
specified range, then the internal reference is currently selected. If the
genlock signal returns to be ok the LED will light up again.
Case genlock =seconds pulse is selected at menu SET - .. - LOCK:
Lights up if genlock is operating normally. This only can be achieved if
the seconds pulse is stable, i.e. the jitter must not exceed 1.2ms.
Flashes if the genlock signal is disturbed or the generator currently
stays in a coarse or fine trim. The coarse trim will be indicated by LED
intern as well. Coarse trim means: frame 0 of the time code is more
than 16ms apart from the seconds pulse. Fine trim means: frame 0 of
the time code is between 1.2ms and 16ms apart from the seconds
pulse.
