D.C. Mun. Regs. tit. 19, r. 19-2114
In mid-ring the referee shall instruct the contestants in the following manner:
"You are to box_____ rounds, under the rules of the District of Columbia. Do not hold behind the neck and punch with one hand. Do not strike a rabbit punch. Do not strike a kidney punch. Do not use backhand blows. Do not hit on the break away at any time. Step back cleanly, and break when I tell you to do so. Do not make me pull you apart."
"In case of a knockdown, I want the contestant scoring it to retire immediately to the neutral corner farthest removed from the knockdown and remain there until I motion him (or her) back, or I will stop counting. A contestant who has been knocked down shall take a count of eight. Penalties are scored in case of fouls. If you lose on a deliberate foul, your purse may be forfeited."
"Keep your punches up."
"Shake hands now and come out boxing. Do not shake again until the beginning of the last round."
While instructing the contestants, the referee may demonstrate the instructions for the benefit of the contestants and spectators.
