HINT: The UNLOCK and BACK WINDOW functions operate even when any of the doors is open.
c. Check the chattering prevention function.
1. Check that the corresponding operation occurs only once, and not repeated continuously while the switch is kept pressed. However, when the switch is operated repeatedly at 1 second intervals, check that the corresponding operation is carried out.
