(4) Input the number of the block to be skipped from the numeric keypad.
Example: If block number 3 is input, the green display (B 3P) changes
to a yellow display (B 3S).
(5) A red display (e.g. B 3S), indicates that the block is already skipped in the
production program transmitted from the F4G. This cannot be cleared at
the machine.
(6) Input the number of a skipped block (displayed in yellow) once more to
clear the block skip function and change the display of the block number
back to its original state.
Example: Input block number 3 again to change the yellow display (B
3S) back to a green display (B 3P).
(7) When the block skip function has been set correctly, press the [RETURN]
key to return to the original display.
