Hello list: I just got my talking meter yesterday and have read the manual. I am really confused! What is the purpose of the function button in the middle; I don't see that is does much of anything? How does the talk button on the meter face work as a lock? There sure are ceveral mistakes in the book; I guess it was translated from Chinese! I would like to hear the experiences of some of you, please. 73 Lowell W8QIY
