CSIP Level 1 Troubleshooting: Known Symptoms, Causes, and Corrective Actions
Incompatible
Hardware
Shutdown Error
EnVisor transducer connector modules and TR boards can be physically installed into HD11 sys-
tems. This creates an untested, therefore unapproved, system configuration. To check for this
unwanted condition, at power on, the system conducts a check of the tranducer connector
modules and the TR boards to determine if they are the correct type for the system: If one (or
more) of these boards is not the correct type for the system, the following type of error mes-
sage is displayed and the system is prevented from imaging.

System monitor has a “shuddering” display or noise in the image.
Consider the possibility of EMI or RFI as described in “Checking for EMI and RFI” on
page 178. Check print quality for similar noise. If it is on the printout, it is probably an
internal system failure. Troubleshoot the PCBs.
