Understanding Advanced Diagnostics.
Advanced Diagnostics is used when displaying Error
Conditions. It will display a series of blink sequences
that help you identify the cause of the error and
potential solutions.
All Error Conditions are displayed with the Error LED
and Standby LED flashing back and forth. The
number of flashes between each pulse denotes a
potential Error Condition (except reverse polarity and
low-voltage battery).
