which is displayed in sec. on the display, after the desired time has passed perform a P/P com-
mand, the M2 door will close first, then pressing the P/P command again will cause the M1 door to

equal to 0, simply press the P/P button two times after learning the automatic closure time.

different screens, where the thousand units are indicated by the lighting up of the point. To reset
this counter, simultaneously press and hold buttons P1 and P2 (ENTER/UP-DOWN) until 0000 is
