7.10 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. In addi-
tion special symbols are displayed which show the respective status of the function keys
and the operating status of the machine. Each time a function key is operated, a signal tone
is given to confirm the input. If the desired input is invalid, e.g. because the maximum para-
meter input value has been reached, a double signal tone is given.
7.10.01 Screen displays
Activated functions are displayed with a triangular marking 2 below or next to the respec-
tive function key.
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 “Parameter settings“ of the appropriate Adjustment Manual.
7.10.02 Function keys
The function keys described below are used basically to switch machine functions on and
off.
If a corresponding value has to be set for the activated function, this is carried out with the
corresponding +/- key.
By pressing and holding the corresponding +/- key, first the numerical value shown above
the key is changed slowly to begin with. If the +/- key is held down longer, the value
changes more quickly.
