SECTION 5 - TROUBLESHOOTING
The CMS will identify problems by alternately flashing a message code and the serial number of
the instrument affected. Table 11 provides a guide to identify causes of problems and determine
appropriate actions to resolve the observed problems. If problems are encountered and factory assistance
is desired, please contact the factory.
