Introduction
General
Transceiver components and controller components reside on
separate circuit boards. Refer to the model charts located in the front
of this manual (prior to Section 1) to determine the controller board
and transceiver board unique to your model radio. Then locate the
appropriate transceiver board and controller board component
location diagram, schematic diagram, and parts list located in this
section of the manual.
Component location diagrams of the controls flex, two front cover/
display flexes, and the strip connector are also located in this section.
A miscellaneous parts list accompanies the flex circuits.
Almost all circuit boards in this family of radios are either six or eight
layers. Layer 1 is the outer most layer viewed from side 1, and layer 6
or 8 (as applicable) is the outer most layer viewed from sine 2. A typical
8-layer circuit board detail, viewing copper steps in proper layer
sequence, is illustrated in Figure 18.
Transceiver
Frequently, transceivers that use a common transceiver board will be
combined into one component location diagram, one schematic
diagram, and one parts list. The differences between transceivers will
be noted throughout the applicable parts list.
Controller
Frequently, controllers that use a common controller board will be
combined into one component location diagram, one schematic
diagram, and one parts list. The differences between controllers will be
noted throughout the applicable parts list.
