3 Regulate the movement
3.1 Pulse controlled slave clocks (NU 90t / NU 90t SYN)
Push button (A) and turn, until hour and minute – hands shows desired time.
Never turn the second hand manually, as this will damage the movement.
Also, the minute hand may only be turned in clockwise direction.
Hand will be set with each minute pulse!
If there would be a difference of 1 min. between
master clock and secondary clock time, move
the plug (B) to the opposite pair of pins to
reverse polarity and set minute hand 2 minutes
forwards.
3.2 Autonomous radio controlled movements (BU 190t, MLU 190t, xTBU 190t, SU 190t)
No time settings needed, clock will set up automatically to current time.
Movements are set by factory to standard run mode (DIP switch for 12:00 position in OFF position).
If a clock does not run to correct time, set 12:00 position DIP switch to ON and check, if the hands are stopping
at 12:00 position exactly (if not, remove the clock hands and fix them exactly at 12:00 position).
Correct time and guaranteed time and power reserve, as well as precision of the clock can only be guaranteed
after 2-3 days of working.
For further information read the documentation of respective movements
(see 2.7 ).
