24 07 (7ms) 01 - 15 [X1] (1 - 15ms) First OFF time for lower thread detect pin
26 03 (30ms) 00 - 05 [X10] (0 - 50ms) Time delay from the time the thread wiper turns OFF to
the time when the lower thread detect pin turns ON

Notes
(a) The timer-off function for the presser foot is activated only when memory switch 36 is set to off.
(b) The indicated parameters are only enabled when memory switch 35 is set to ON.
(c) The lower thread detection function for the needle up/down stop when the pedal is positioned at neutral is activated
only when memory switch 51is set to on.
(d) The indicated parameters are the settings when memory switch 22 is set to ON.
