Key Answer Only
This feature has two options, On or Off.
When a call is incoming, opening the phone normally answers it. If you wish to open the phone without answering calls, set Key Answer Only to On. Then, if your network offers Caller Line Identification and you are a subscriber, you can open your phone to review the number or name of the caller before you answer. To answer a call with Key Answer Only activated, press O, 1 through 9, or >.
To reject the call, press C.
When set to Off, opening the phone answers an incoming call.
