NEC XN120 Feature Manual page 155

Conditions
A) When a key is programmed using service code 852, that key cannot be reprogrammed with a
function using the 851 code until the key is undefined (000). For example with a Park Key
programmed by dialling 852 + *04 must be undefined by dialling 852 + 000 before it can be
programmed as a Voice Over key by dialling 851 + 48.
B) Using Program 92-01 to copy a system phone's Programmable Function Keys will copy all
the keys whether they exist on the phone to which the programming is being copied. This may
cause confusion when trying to define a key which is already defined but which doesn't exist
on the phone (will display as "DUPLICATE DATA". It is recommend to either clear these
non-existent keys or to only copy from an extension which has the same or fewer numbers of
keys than the extension to which the programming is being copied.
Default Setting
The 12 function keys are line keys (e.g., key 1 = line 01) for lines 1 to 12.
Speed dial keys 1 to 9 are not defined.
Speed dial key 10 is a Loop Key (type *05+0).

n 24 Button Add on Console
The 24 button add on console can be attached to any XN120 Vision phone and will provide 24
additional programmable function keys.
The keys can be programmed by the user with service codes 851 or 852 in exactly the same way as the
22 function keys on the phone.
They can also be programmed within XN120 Configuration Mode using program 15-07-01. The add
on console uses keys 23 to 46 within program 15-07-01.
