System Busy
If the forced installation is attempted while a line/trunk or extension is busy,
the following screen appears.
System Busy - Pls Wait
Dial Code:xxxx S/P:ss/pp
Exit
When all lines/trunks or
extensions
are freed, the installation continues. Select
Exit
to return to the System menu and cancel the installation. If system
software is corrupted, system maintenance may not provide an accurate
indication of busy lines/trunks or extensions. If this seems to be the case
verify that the listed extensions are truly not busy; then perform the installation
by power-cycling the system. See Step 3 above.

The system is in an indeterminate state. Re-initiate the forced installation by
power-cycling the system after inserting the memory card.
