COMMERCIAL IN CONFIDENCE
Chapter 1:Diagnostics & Software Upgrades
Use this chapter to investigate faults and to upgrade software on ST70 instruments and pilot controllers.
1.1Diagnostics
In the unlikely event that a problem occurs with an ST70 product, use this section to resolve the situation.
First considerations
If an ST70 product is not performing as it should:
• Ensure it is being operated in accordance with the relevant Operating Guide:
• Ensure that any data that seems to be missing is actually available to the product. For example, if wind
data is not available, there will be no wind-related
data either.
• If specific data types are missing or incorrect:
• Check the relevant Transducer and Pod, including the connections between them and to the system.
• If speed readings are missing or obviously wrong, the speed transducer paddle wheel could be fouled
and need cleaning
• Take into account any changes that may have been made to any associated electrical system. Such
changes could affect the performance of an ST70 product.
• Be aware that radio signals transmitted in the proximity of an ST70 product could affect the performance
of the product.
If you are satisfied that the problem is not due to any of the above, use the diagnostic tools below to isolate the
cause of the problem.
Diagnostic tools
The following tools are available to aid diagnosis:
• About Display function.
