Manual I require a manual for an Audioline FF777 Cordless Telephone. Can you help please I have replaced the batteries with the correct type of batteries.  I have checked the connections.  I have charged the new batteries.  I called the phone co. and the inside and outside lines were checked.  I still have no dial tone although the screen lights up and the phone rings when someone calls.  The caller hears a fax-type noise even though are fax machine is on a separate line.  I don't know what else to do.  This phone is about 2 years old.
