October, 1898 page inside front cover General Information. SUBSCRIBERS' NUMBERS.- Each subscriber's telephone is designated by a number placed to the left of his name. The number is prefixed by the name of the exchange with which the subscriber is connected. In calling for subscribers, it is necessary that both the exchange name and number be given. INSTRUCTIONS FOR USING TELEPHONE.- In talking, speak in a moderate tone and directly into the transmitter, with the lips as close as possible to the mouthpiece. To call Central Office, take the hand telephone from the hook, place to your ear, and operator will say, "Number?" When operator receives exchange name and number of subscriber wanted, she will repeat them to you in order to avoid mistakes. Remain with telephone to your ear until party called for has answered. Should the operator connect your line on to the phonograph and you hear the words, "Line is busy, call again," it means that the desired subscriber's line is connected with some other. Should the operator say: "The party called for does not reply; if you wish, I will call you when we can get him," you will kindly give us the number of your telephone, if you wish us to do so. When a conversation is finished, be sure to replace the hand telephone on hook in original position. HOW TO ANSWER A TELEPHONE CALL.- Remove the telephone from the hook and say: "Here is Main 297" (or whatever your number may be.) The party calling should say: "This is Main 298" (or whatever the number may be). Much friction and annoyance will be avoided if this simple plan is carried out. TELEPHONE MAIN 600.- In addition to the original use for which this department was established, that is, the reception of complaints, and for the general benefit of the service, more operators have been added whose duty it is to give attention to subscribers asking for general information regarding change of subscribers' number, name, location, names not in book, etc., etc. These operators are not permitted to receive calls or make switches to subscribers whose names are regularly printed and numbered in the Telephone List. NON-SUBSCRIBERS.- When it is desired to have a non-subscriber called into one of our public offices at a distant place, a messenger will be sent for at the expense of the party ordering service. Non-subscribers can have the same service as regular subscribers by application at any of our public offices and paying our established rates. (end of page)
