Troubleshooting Sequence
Troubleshooting Sequence
Refer to Figure 4-1 for the troubleshooting sequence for the
auxiliary terminal. Each block of the flow represents a single
task that must be completed before continuing with the
sequence.
In some cases, more than one path can be taken. For paths
that are in parallel, either complete all of the tasks in all of the
paths before continuing or complete all of the tasks in only
those paths that apply before continuing. At least one path
must be completed.
Some blocks contain alphanumeric codes. These codes identify
the procedure that describes the steps to complete an indi-
cated task. Complete all of the steps given in a procedure
before continuing to the next procedure.
The procedures have check boxes in the margin by each proce-
dural step. When performing a procedure, check each box as
each step is completed.
By treating each task as a separate entity, the procedures pro-
vide an easy method for finding the information needed to per-
form each task in the troubleshooting sequence.
