Manual Adjustment Procedures
Introduction
Adjustable and Factory-Selected Components
Table 3-2 on page 96 lists the adjustable components by reference
designation and name. For each component, the table provides a
description and lists the adjustment number.
Refer to Table 3-3 on page 98 for a complete list of factory-selected
components used in the instrument along with their functions.
Factory-selected components are identified with an asterisk on the
schematic diagrams.
Adjustment Tools
For adjustments requiring a nonmetallic tuning tool, use fiber tuning
tool, part number 8710-0033.
Two different tuning tools may be necessary for IF bandpass
adjustments, depending upon the type of tuning slug used in the
slug-tuned inductors. If the tuning slug requires a slotted tuning tool,
use part number 8710-1010. If the tuning slug requires a forked tuning
tool, use part number 8710-0772.
Never try to force an adjustment control. This is especially critical
when tuning variable capacitors or slug-tuned inductors. Required
service accessories, with part numbers, are listed under
Service Kit, in
Chapter 1 , “General Information.”
