NEC 16D and 8D Quick Start User Manual

What you need to do is, set up a button that will turn forwarding on. then set a number in manager on the forwarding tab, set the number. If the number is going to change a lot, then you should set a second button up as, forward number. One changes or sets the number, and the other toggles forwarding on and off

Who provides your dial tone? You will have to find out their code for forwarding calls to a cell.

SBC/AT&T/Ameritech uses #72, then dial the number you want to forward to

Call forward, off-premise is available on the NEC Electra Professional phone system if you have the Level II system (metal cabinet, not plastic) and you have system software level 700 (7.00) or higher. To get your system software level, press <FNC> - 3 from any display telephone when idle. The procedure to forward is (with phone idle): press <FNC> - dial 60, dial trunk access code (usually - 9), dial telephone number, press <FNC>. Additionally, your station class must be set to allow this feature (by default it is not allowed) and you may need trunk-to-trunk capability turned on in system programming (which is also, by default, not allowed). Hope that all helps.

Usually there are codes for call forwarding and forwarding cancel. I always program up *8 for call forward and #8 for call forward cancel. On your phone try a few numbers. First try *1 make sure you are on a phone with a display. Read the display and see what it says. If it is not what you need hangup. Then try the next number *2. Remember the #_ is usually the cancel.
Good Luck
