 CENTRAL MAINTENANCE COMPUTER - OPTION CODE INSTALLATION
_______________________________________________________
 1.  General_______
 A.  This subject has one task. The task is to install the option code in the central maintenance computer (CMC).
 B.  It is necessary to use one of the CDUs to install the option code.
 TASK 45-10-01-472-061
 2.  CMC Option Code Installation____________________________
 A.  General
 (1)  
The CMC must contain the correct option code. Without a satisfactory option code, the CDU shows only the CMC CONFIGURATION DATA page when you push the <CMC LSK. You cannot use the other CMC functions until the CMC contains a satisfactory option code.

 (2)  
Option code installation is necessary after you replace the two CMCs or after you install software in the two CMCs. Some service bulletins also refer you to this procedure to change the option code. The option code is automatically transmitted from one CMC to the other. Thus, it is necessary to install the option code only once for the two CMCs. It is not necessary to install the option code after you replace only one CMC or after you install software in only one CMC.
