440 GENERAL SCIENCE 



To recall the operator, move the receiver hook up and down 

 slowly. 



When you have finished talking, say " Good-bye " and replace 

 the receiver on the hook. 



Remember, courtesy over the telephone is always desirable. It 

 wins friends for you. 



ON ALL INCOMING CALLS 



Answer your telephone promptly and pleasantly. 



Announce your name. Don't say " Hello." 



Be ready with pad and pencil in order not to keep your caller 

 waiting. 



Listen attentively so that you will not have to annoy the caller 

 by asking him to repeat. 



Maintain the same courtesy and consideration in a telephone 

 conversation that you would in the person's presence. 



" The voice with the smile wins."
