USER (SET, TTT ...) Shows the pre-set of the user bits mode. Change the mode with key
OFFS off (± ± ± ± 01..23) An offset (full hours) may be added to the reference time input. With key
Pressing the enter key the factory settings will be stored in the backup
memory and in the actual area.
Attention: This action will restart the G 30 TTT just like a power-on!
Pressing the enter key will switch between on and off.
On means: time and date of the (built-in or external) DCF77 or GPS
receiver will be accepted, i.e. every second the "real-time" of the MTD
user bits will get its update. During the operating mode "real-time" of
the generator the LTC time will update once a day or after pressing key
real-time.
Off means: time and date of the (built-in or external) DCF77 or GPS
receiver will not be accepted, the status LED's at the front however
remain valid. Time and date now may be set using a MTD user console.
Pressing key real-time will transfer the time of the internal clock
(identical to the time of the MTD user bits = real-time) to the LTC time.
Pressing the enter key will select an hour out of 00 - 23. In the "real-
time" operating mode (key real-time) this will be the hour at which the
LTC generator automatically synchronizes to the time of the GPS or
DCF77 receiver. This happens once a day, and a frame discontinuity
may occur. So this event should be chosen to happen at a time - mostly
at night - where it causes no further problems. The standard setting is =
03. The hour has to match with the reference input time of the GPS or
DCF77 receiver, i.e. whenever G 30 TTT detects this hour anew from the
reference input time, the synchronization occurs.
Pressing the enter key will switch between different frame rates. This
selection changes the internal free-run oscillator, the generation of the
LTC time information and the way of counting the MTD times A...I.
Frame rate = 24:
Frame rate = 25:

enter (see chapter "User bits mode"). After a long press at key select -
while the menu is switched off - the user bits mode can be switched
between "TTT" (i.e. LTC(MTD) will be generated) and the mode selected
at this menu.
enter select off or 01 ... 23 or -01 ... -23 (see chapter "Offset to
reference time input").
