5.3 FAULT FINDING
The unit is a modular design, which simplifies fault finding to a card or assembly level.
Section 6, which starts on page 38, provides guidelines to fault finding and repair to
modular level. The status LED indicators on the Processor card provide a visual
identification of the fault condition existing on the unit.
The software has a diagnostic routine which, when accessed by the handset, can
identify many other types of fault conditions.
