7.3 TROUBLESHOOTING FLOW DIAGRAMS
The troubleshooting flow diagrams are gathered in this chapter. These diagrams
are meant only for maintenance technical personnel.
By starting from a bad functioning symptom we arrive to the corrective operation to
be carried out in order to remove the failure; the corrective action can be a simple
maintenance operation (III level excluded) or it can end in sending the equipment
to the OTE assistance centre.
The troubleshooting flow diagrams relative to the radio terminal PUMA T2 are
gathered in par. 7.3.1.
