66 Disassembly and repair
Note
For information about screws or connectors used in the device, see the Appendix.
WARNING Safety risk. Do not attempt to service the device when the
device is connected to a patient.
CAUTION Before disassembling the device or installing options,
disconnect the patient from the monitor, power down the device,
disconnect the AC power cord and any attached accessories (SpO2
sensors, blood pressure hoses and cuffs, temperature probes, ECG
modules, Braun docks, and barcode scanners) from the device.
CAUTION Remove the probe well in the temperature module prior to
disassembly.
CAUTION Perform all repair procedures at a static-protected station.
CAUTION When the device case is opened, regard all parts as extremely
fragile. Execute all procedure steps with care and precision.
CAUTION Observe screw torque specifications, especially with screws
that secure directly into plastic standoffs.
CAUTION To avoid mismatching screws and holes, keep the screws for
each piece with that piece as you remove modules and circuit assemblies.
It is possible to mistakenly install machine screws in locations intended for
plastite screws. Plastite screws in this device have a Torx-pan head.
CAUTION After performing any of these procedures and prior to returning
the device to service, you must use the service tool, Gold licensed 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.
EarlySense and CO2 can be installed only on the extended chassis.
