Network feature setting
Call forwarding, call waiting, and send own number are
network services available through your service provider.
These features do not appear in your phone’s Network
services menu until you save the related feature code(s)
given to you by your service provider. After you save the
feature activation or cancellation code, the feature appears
in the phone’s menu and you can use the menu to turn the
feature on or off.
Note: Feature codes can be saved only when your primary
phone number (NAM 1) is selected. See page 33.
