Initial Observation
The RF500A Gateway may be initially observed in various states. It is important to record the details about this state
before performing further tests, this information may prove useful in later fault diagnosis.
Referring to both Appendix-A – Front Panel Indicators ,Appendix B – Status Indicators and Appendix C – Website
Error Messages, record carefully which indicators are showing. Of course if a recognised fault is indicated, we could
continue testing to determine whether that particular fault recurs. If the device manages to boot up, Appendix C –
Website Error Messages lists the possible error messages for further fault diagnosis.
Status Indicators
Note that the status indicators as described in Appendix B – Status Indicators are only capable of displaying one fault at
a time. In the event that there my be multiple faults the highest priority fault will be displayed until fixed.
The status indicators are only active for fault status display while the PC module is off, once booted the module has
control of these indicators for activity indication.
