This manual has been designed to aid you in isolating a
problem to a field replaceable unit (FRU) and then to
remove and replace that unit.
The MAPs section aids you in isolating the problem to a
failing FRU and the Maintenance Information section
contains adjustment procedures, removal and
replacement procedures, and diagnostic and online test
information.
You should first use the MAPs section to identify the
failing FRU and then go to the referenced maintenance
information for the suitable repair action.
No scheduled preventive maintenance or special tools
and test equipment are required to service this display
station.
The format for page numbering is X-YYY. X is the
section number and YYY is the page number within that
section. For example, 1-22 is page 22 in Section 1.
Three digit reference numbers are used in the MAPs and
text to index the maintenance information. In the MAPs
and text, these numbers are in parentheses. For
example, 110 refers to Description and Parts Location
under 100 Keyboard Unit.
MAPs SECTION
The MAPs section contains MAP charts that help you
isolate a problem to a failing FRU. Three-digit reference
numbers refer you to the suitable maintenance
information to adjust or replace it.
