time/user Switches the display to show the time or binary groups information of the
time code. Terminates any menu operation.
key lock Switching on (LED lights up) or off (LED off) the Key Lock feature.
Key Lock “on” means: the buttons enter, intern, genlock, time, timer, tc and
start are without function. So an unintentional key stroke do not lead to an
unwanted function, only the display can be switched. Setting time or date
using an operational unit of the MTD system is disabled.
intern Switches on the genlock to internal reference signal (temperature
compensated x’tal).
genlock Switches on the genlock to the input source as selected at the menu SET -
LOCK. Input genlock can be one of three sources: video or black-burst, LTC
input signal, seconds pulse of a real time reference.
time Select LTC generator operating mode: reference time input. The LTC time
information corresponds to the reference time input (± offset as selected at
the menu ZONE - OFFS1 and OFFS2).
With every key stroke the generator synchronises again to the reference
time, so the generator is forced manually to a synchronisation additional to
the automatic synchronisation as selected at the menu REFER - MODE1 and
MODE2.
timer Select LTC generator operating mode: time of a MTD timer. The LTC time
information corresponds to one of the MTD timer A - F, as selected at the
menu TIMER - TIME A-F.
tc Select LTC generator operating mode: LTC Jam-Sync feature. Transfers
data from LTC input to LTC output, as selected at the menu LTC IN -
MODE.
start Select LTC generator operating mode: free-running mode.
If enabled at submenu SET - ... - PARA: with every further key stroke the
time value which has last been chosen as a start value (menu SET - START)
will be transferred to the LTC time information, and the generator keeps on
counting continuously from this start value on.
