3.1 Introduction
When the system or the 3514 displays a 3514 reference code (URC):
1. Go to the "Unit Reference Code Table" in topic 3.2 and find the unit
reference code in the table. The "Unit Reference Code Table" is
arranged in reference-code sequence, with numeric characters appearing
before alphanumeric characters. For example, reference codes AAA0
through AAA9 appear before reference codes AAAA through AAAF.
2. If a problem recovery procedure is indicated with a unit reference
code (URC), perform the problem recovery procedure. This procedure
will direct you to exchange procedures. If the problem recovery
procedure does not correct the problem, exchange the remaining failing
items one at a time until the problem is corrected.
3. Use this table for a list of the failing item part numbers, a
description of the failing items, and a document reference (if any)
including a recovery procedure for the parts that need to be
exchanged.
4. If no problem recovery procedure is indicated with a reference code,
exchange the failing items, starting with the failing item that has
the highest percent of probable cause. Exchange the failing items one
at a time until the problem is corrected.
