HOOTING
Below are two lists; a list of standard operating codes and
a list of fault codes. The fault code list provides diagnostic
and troubleshooting information to help determine the
problem and fix it. Standard operating codes are not fault
codes and the presence of a standard operating code indi-
cates a no-fault condition.
NOTE: Verify display orientation is correct before interpret-
ing fault codes. Otherwise, the fault codes may be upside-
down. If a fault code or operating code is not on these
lists, the display may be upside-down.
