otherwise noted, the assembly procedure is the reverse of the disassembly procedure.
An exploded view of the assembly precedes disassembly instructions, with callouts referencing the
parts.
Each part’s disassembly instructions might include one or both of the following:
•
Reassembly notes
: This contains information specific to reassembly not addressed in the
disassembly instructions.
•
When replacing the component
: This contains information specific to installing a
replacement part.
For information about screws or connectors used in the device, see “Screws” and “Connectors” in
the appendices.

service, you must use the service tool, Gold edition, to complete the full suite of
functional tests to ensure that all systems are operating within the design
specifications. For more information about these tests and the service tool, see
“Functional verification and calibration.”
If you do not have the service tool, contact Welch Allyn Technical Support.
