My line 2 answers on just the 2nd ring. When I do the ring delay instructed in the book it isn't correct. You tell me to go to MENU and scroll down until it says Answering Sys. I don't have that. I only have 4 catagories. 1. Display Settings 2. Sound Setting 3. Phone Settings, 4. Restore Settings. How on earth do I get this to change????
