System Advisory messages are displayed on the scratchpad line (line 8.) of the CDU. Advisory messages may occur at any time on any page. When a message is displayed, it will remain displayed un- til depression of the CLR FAB. No other data may be en- tered while an advisory message is displayed, but an advi- sory message will overwrite existing data on the scratchpad line. Once the advisory message is cleared from the scratchpad, previously entered data in the scratchpad will be recalled automatically. A listing of the system advisory messages and their meanings is pre- sented in table 3-22.17. If the FCC detects a fault (on pow- er up) that occurred during the last FCC shutdown se- quence, an extended, or full page advisory message (fig. 3-25.23) will be displayed on the CDU indicating the de- tected fault. Up to two faults from the Extended Advisory Message Table (table 3-22.18) can be displayed on lines 3. and 4. of the CDU display. The extended message(s) will only be displayed if the FCC has enough functionality to perform the task at the time it is required. Depressing any key on the CDU will cause the FCC to attempt to clear the fault(s) and proceed with normal operation. Informa- tion presented on the display should be recorded for maintenance action prior to clearing the fault condition. Table 3-22.17.
