Assign functions or direct-dial numbers to the programmable keys on the right-

hand side of your phone. 
You can assign two different functions to each key; to switch between func-

tions, press and release the shift key 

=

 and then press the appropriate mem-

ory or function key. Each assignment is programmable as a direct-dial number 

or a function. The keys are designated from top to bottom as P1 to P5, and P6 

to P10 after pressing the shift key.
The following function keys have default settings:
P1 [Hold]

P2 [Transfer]

P3 [Conference]

P4 [DND]

P5 [Headset]

For example: if you want to assign a direct-dial number to the P1 key, you 

must first reassign the [Hold] function to another key and then reprogram 

the P1 key.
