INTRODUCTION
6-2. This section contains information for
ordering parts. Table 6-2 lists abbreviations used
in the parts list and the names and addresses
that correspond to the manufacturer's code
numbers. Table 6-3 lists all replaceable parts in
reference designator order.
Any service or adjustments performed with
the protective covers removed should only
be done by qualified service personnel. A
shock hazard exists with the covers
removed.

EXCHANGE ASSEMBLIES
6-4. Table 6-1 lists assemblies within the
instrument that may be replaced on
an ex-
change basis, thus affording a considerable cost
saving. Exchange, factory-repaired and tested
assemblies are available only on a trade-in
basis; therefore, the defective assemblies must
be returned for credit. For this reason, assem-
blies required for spare parts stock must be
ordered by the new assembly part number.
6-5.
ABBREVIATIONS
6-6. Table 6-2 lists abbreviations used in the
parts list and schematics. In some cases, two
forms of the abbreviation are used, one all in
capital letters, and one partial or no capitals.
This occurs because the abbreviations in the
parts list are always capitals. However, in the
schematics, other abbreviation forms are used
with both lower case and upper case letters.
