To override the configured telephone number, press NUMBER, LSK
[3L]. This highlights the NUMBER field and allows the displayed
number to be edited or a new number to be entered. An entry of up to
19 digits is acceptable. The new entry will remain active until the
system is restarted, or the number may be restored to the configured
value by pressing the [BACK], then [ENTER] keys. From the
CDU/MCDU keyboard enter P for pause, L for #, or A for *.
Contact your DSP for the appropriate telephone number.
