Disassembly And Repair - Welch Allyn Connex 6000 Series Service Manual

Disassembly and repair

These procedures provide instructions for device disassembly and board removal. Except
where 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. In the instructions, numbers in parenthesis refer to callouts in the
exploded drawings.
Each part's disassembly instructions may 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
new option or replacement part.
For information about screws or connectors used in the device, see the appendices.
Note After performing any of these procedures and prior to returning the device
to 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.
