7.06 Control panel
The control panel is used to call up machine functions for setting up the machine and for
sewing operation, for entering parameter values and for reading error messages and service
settings.
The control panel consists of the display 1 and the function keys described below. The dis-
play 1 consists of a two-line alphanumerical LCD display with 16 symbols per line. The func-
tion keys 2 are located below and to the right of the display. The status of the function keys 2
and the operating status of the machine are shown by LEDs in the respective keys.

Every time the function keys 2 are operated, a key tone sounds as confirmation of the
input. If the input required is invalid, e.g. because the max. permissible value for the
parameter input has been reached, a double tone is audible. An SD-card reader for data
transfer is integrated.
7.06.01 Screen displays
●In the sewing mode all relevant sewing data is displayed and can be changed directly, de-
pending on the status of the machine, see also Chapter 10 Sewing.
●During the parameter input the selected parameter number with the corresponding value
is displayed, see Chapter 13.41 Parameter settings.

7.06.03 Function keys
The functions keys described below are used essentially to switch machine functions on and
off. When the function is switched on, the diode in the key is illuminated.
If a corresponding value has to be fixed for the activated function, this can be carried out
with the corresponding +/- keys 3.
By pressing and holding the corresponding +/- key, firstly the numerical value displayed abo-
ve it is altered slowly. If the +/- key is pressed longer, the numerical value changes more
quickly. The respective +/- keys shown opposite are described below.
Stop
●When operated during a sewing cycle, the machine is stopped.
●When entering the code number this key corresponds to the figure 1.
Tacting forwards
●This key is used to tact forwards through the entire sewing cycle step by step.
●When entering the code number this key corresponds to the figure 2.
Danger of needle breakage!
Before tacting move the needle to its t.d.c. using the balance wheel.
