4 Verify that the wide, flat flex cable connecting the wireless card to the CPU PCBA is fully
inserted at both ends.
a If the flex cable is connected and the wireless diagnostic said that the wireless card is not
present, replace the flex cable.
b If the flex cable is connected and the diagnostic said the test failed, replace the wireless
card and the flex cable.
c If the flex cable is connected and the diagnostic passed, replace the wireless card.
5 If the above does not solve the problem, replace the CPU PCBA.
External Alarm Troubleshooting
1 Independently verify the operation of the nurse call box. Replace if it does not work correctly.
2 Verify that the alarm cable is installed correctly and that pin 4 on the connector has +12 V.
3 If the problem persists, inspect the I/O bay PCBA and the interconnect PCBA. If any connectors
or parts on either of these assemblies appear damaged, replace the damaged assembly.
4 If the problem persists, replace the CPU PCBA.
Remote Display Troubleshooting
1 Check the external monitor power and video cables for proper connections. Verify that the
display assembly is set in the right operating mode (RGB analog video, separate vertical and
horizontal sync).
2 Verify that the external monitor brightness, vertical, and horizontal sync are set correctly.
3 Verify that the external monitor’s terminations are set for 75 ohms, if settable.
4 Run the video diagnostic (refer to Diagnostic Menus on page 5-6). If it fails, replace the CPU
PCBA.
5 Inspect the interconnect PCBA and I/O bay PCBAs. If any connectors or parts on either of these
assemblies appear damaged, replace the damaged assembly.
Mouse or Keyboard Troubleshooting
1 Try another mouse or keyboard (there is no setup for the mouse or keyboard, either externally
or internally). Cycle the power ON and OFF after changing the keyboard or mouse to guarantee
that they are seen by the monitor.
2 Run the keyboard/mouse diagnostic (refer to Diagnostic Menus on page 5-6). If it fails, replace
the CPU PCBA.
3 Inspect the interconnect PCBA and I/O bay PCBAs. If any connectors or parts on either of these
assemblies appear damaged, replace the damaged assembly.
