10.0 TROUBLESHOOTING
10.1 Overview
The 20 kHz HF APR generator has an extensive internal monitoring system. A number of
error codes are displayed to alert the operator or service engineer to the status of the
system. Some error codes are momentary alerts, and will automatically reset once the
offending button has been released. Other error codes indicate simple or serious
problems with the system. The chart below shows all error codes, what they mean, and
how to correct them.
