Conditions
When a key is programmed using service code 752, that key cannot be
programmed with a function using the 751 code until the key is undefined (000).
For example with a Park Key programmed by dialing 752 + 04 must be
undefined by dialing 752 + 000 before it can be programmed as a Voice Over key
by dialing 751 + 48.
When assigning a CAP key, 08, an orbit number must be used. If orbit 000 is
used, it automatically assigns the next available orbit.
