11) Protection against crushing
This option allows you to set the security level. A lower value means that
less force is required to stop the door from moving downward. The
recommended value at the beginning is 0. When the door stops, it will
move back and wait 10 seconds. Make sure that there are no
obstructions in the path of the door, the guides are installed evenly and
the surface provides sufficient sliding (use lubricant if necessary). After a
time try out a higher degree of protection.
12) Current time
The message means that the next screen will allow you to select the
current time (in 24-hour format). Pressing the "FUN" button will take you
to the next screen with settings.
To change the current time, press the "UP" or "DOWN" buttons. Press
the "FUN" button to toggle between setting the hours and minutes.
Pressing the "FUN" button will take you to the next screen with settings.
