SECTION 5 Maintenance and Troubleshooting System Troubleshooting
System Troubleshooting
If during the system startup, the tow vehicle activation, the predeployment
checks, or the operation of the system, either the SIP-150 Sonar Image
Processor or the TTV-195 Tow Vehicle does not appear to be functioning
properly, refer to the troubleshooting guides in this section and to the
functional descriptions in Section 4, "Theory of Operation." The
troubleshooting guides will assist in quickly isolating the problem, and should
the problem be in the processor or subsea electronics, the theory of operation
will assist in tracing the source of the problem to the subassembly or
component.
