3.343

The rule for striking the mallet for silence: The karmadāna first assumes full deportment outside the door, clasps his hands, enters facing sideways along the door, and upon arriving at the place of striking, stands and joins his palms. With his right hand, he takes the mallet and raises it, aiming at the block; only then does he strike one sound, which must not have an echo; then he lays down the mallet, running his hand along from the handle. Afterward, he joins his palms to make whatever announcement is needed; if there are donations, dedication of merit, announcements, and the like, the karmadāna states the circumstances orally. He must not strike the mallet for routine matters, except when the assembly is disorderly, etc.
