REPLACEABLE PARTS AND
DISASSEMBLY
The Replacement Parts and Disassembly chapter lists the
replaceable mechanical components of the GDM-8245 and
shows how to remove the PCBs, panels, and outer casing
from the instrument. The procedures described in this
chapter are intended for parts replacement and board
adjustment. The PCB diagrams included in Circuit Diagrams
and Components Parts chapter (page92) shows more detail
about the electrical components of the instrument and thus
can also be used as a reference.
Before disassembling the instrument, disconnect the
power cord from live voltage sources. Failure to do so may
result in injury or loss of life.
