Designated personnel, while on duty, must have their radio on, the proper channel selected and know that the radio batteries are in good condition. The current radio channel will be posted on bulletin boards. 228. Before transmitting, personnel operating a radio must listen a sufficient interval to be sure the channel is not already in use. 229. The use of "VOX" or voice operated transmission is prohibited and precautions must be taken to avoid activation of this function on a radio. 230. Radio communication must not be used to avoid compliance with any operating rule. 231. Any radio communication which is not understood or completed in accordance with these rules, must not be acted upon and must be treated as though not sent. Exception: If any information is received which would affect the safety of personnel, others, or damage to property; the safe course must be taken, and, if necessary, movement stopped until an understanding has been reached. 232. Radios must be tested at the beginning of a tour of duty. The test must consist of an exchange of voice transmissions with another radio and the quality and readability of its transmissions must be ascertained. 233. When radio is being used in lieu of hand signals both the direction and distance traveled must be given. Movement must be stopped in one-half the distance specified unless additional instructions are received. 234. When train orders are transmitted by radio directly to an addressee they must be transmitted in accordance with applicable operating rules, and the following: A. The train dispatcher shall establish radio communication with the addressee and inform the addressee of the intent to transmit a train order. B. The addressee of the train order shall inform the train dispatcher of the circumstances of their movement, if any, and their exact location. C. After the train dispatcher has ascertained the positive identity and exact location of the addressee, and has determined that is safe to transmit the train order, the train dispatcher shall then transmit the train order. D. After the train order has been received, it shall be immediately repeated in its entirety by the addressee. After verifying the accuracy of the repeated train order, the train dispatcher will respond thus: "(train number or identification of addressee), train order number ______ complete, (the time)". Personnel must acknowledge this response by replying, thus: "(train number or identification of addressee), received train order number ______ complete, (the time completed)". E. Except as provided by Rule 231 a train order transmitted by radio which has not been made complete may not be acted upon and must be treated as though not sent. Rule 214 will not apply. "Complete" must not be given to a radio transmitted train order for other trains until response "complete" has been acknowledged by the train being restricted. F. Information contained in a train order may not be acted upon by persons other than those to whom the train order is addressed. 235. If necessary for clarity, a phonetic alphabet shall be used to pronounce any letter used as an initial, except initials of railways. A word which needs to be spelled for precision or clarity shall first be pronounced, and the word shall then be spelled. If necessary, the word shall be spelled again, using a phonetic alphabet. 236. Where rules require the signature of the addressee to a train order, direct voice communication between the train dispatcher and the addressee of the train order shall constitute fulfillment of such requirement. 237. Provisions of Rule 205 shall not apply when not more than two train orders are in effect.
