i have a vtech 5.8ghz model #cs55111 serial #604678445. when we got the phone they did not give us a manual for it. now the ringer is off and i can seem to find how to turn it on. also there is an answering service on the handset and we dont know how to excess it. i would like to get the manual for this phone but cant find it on the site.it does not have a joystick just a select button in the middle. Please help me. thanks
