Tele means Telephone Number.

Thanks. When I set Contact+Tele+Time I hear a little echo but I set without tele I don't hear echo from records' voices.  They are normal. What do you say about?

"Contact+Tele+Time" or "Contact+Time" only affect the file name of recorded clips, it has nothing to do with the records' voice. You can try it more and compare the result.
