Page 6: Common Repair Scenarios
Common Repair Scenarios Along with using this Service Manual for troubleshooting purposes, it is essential to consult our Service Notices. A complete set of notices will be available concerning current and past faults found on the CT/SSP-800. These are descriptive of the fault along with troubleshooting techniques and solutions. The following cases are described using keywords for the fault. - Page 7 Keywords: On screen error codes X.0.0.0.0. Numerical Error codes such as 2.0.0.0.0 can be displayed when an initialization error has occurred. These errors may arise when taking the CT/SSP-800 out of standby or when powering up. The first number of the error code describes in which stage the error occurred.

Page 9: Does Not Initialize (Standby Led Flashing Continuously)
Does not initialize (Standby LED flashing continuously) A CT/SSP-800 that does not initialize completely will continually flash its blue LED on the front panel. The significance of this is that the internal micro-controllers cannot execute the firmware properly. Probable causes for this are as follows; 1- Corrupted Firmware 2- Bad digital power supplies 3- Sensor board communication errors... -
