CSIP Level 1 Troubleshooting: Known Symptoms, Causes, and Corrective Actions
If an EnVisor ID (D1 or D4) is reported in the error message, a wrong transducer connector
module is installed in the system and must be replaced with a correct one (the Cartridge module
can be used on both systems).
Clicking OK in the error message, displays the Setup window (Figure 5-1). From the Setup win-
dow, you can access any of the Setup menus. If you exit Setup, the system shuts down.
Passwords Don’t
Work
The HD11 system boots to a Caps Lock = on default condition. Verify that the Caps Lock on
indication (A) at the bottom right of the display is off [no (A) showing] to ensure that passwords
entered are not all uppercase.
NOTE The results of changing/switching Caps Lock does not update on display until you go
back to the ultrasound application.
Checking for
EMI and RFI
Electromagnetic interference (EMI) and radio frequency interference (RFI) can degrade the per-
formance of the HD11. For example, a transducer placed close to an ECG cable can increase
interference. Moving the ECG cable or other medical equipment away from the transducer can
reduce interference. EMI and RFI can conceivably cause image noise or monitor distortion if the
system EMI shielding has been compromised. EMI and RFI can be generated by a variety of elec-
trical devices. The interference can be transmitted over power lines or radiated through the air.
Answering the following questions can help locate the source of interference and help determine
whether the problem is with the system or with the scanning environment.
• Is the interference intermittent or constant?
• Does the interference appear with only one transducer or with several transducers?
• Do two different transducers operating at the same frequency have the same problem?
• Is the interference present if the system is moved to a different location in the facility?
