NEC Topaz Line Port Setup

[weealbie]

Hi guys, first post on here so apologies if it's been answered already.

I have an NEC phone system with NEC IP2AT phones. Function keys 1 - 6 are setup and line ports on every phone except one where keys 4, 5 and 6 are not defined.

I need to set them up as line port 4, 5 and 6 but the programming is not allowing me to. Is there something i am missing with the coding?

Any help would be greatly appreciated.

To program a line key on a handset :-
1. Press idle CALL key.
2. Dial 852.
3. Press the key you want to program.
4. Enter the 3-digit key function and any additional information needed for the key.
Available functions are *00-*99 (refer to chart) and line keys 001-200.
To un-define a key, enter 000.
When a key is programmed using service code 852, that key cannot be programmed with a function using the 851 code until the key
is undefined (000).

The code for a line key is *01 then 3 digit line ie 004 for line 4
