1.4 Identify existing warranties, service agreements and equipment specifications and documentation covering digital reception equipment

1.5 Select and obtain tools and materials appropriate for the work order

2. Assess likely cause and location of fault

2.1 Verify system details to assist with fault identification

2.2 Assess available data and historical trends to determine likelihood of fault being the set top fault or existing customer equipment or cabling fault

2.3 Rank likely causes of fault in order of probability ensuring a methodical approach to fault-finding is used

2.4 Discuss problem fully with customer and advise of likely charges

3. Perform tests to diagnose fault

3.1 Conduct visual inspection of system for likely damage following work health and safety (WHS) and environmental requirements

3.2 Check connections, plugs, terminations and leads for operation

3.3 Measure signal strength at wall plate and beyond to ensure adequate signal level for equipment processing

3.4 Conduct functional test of facilities to identify faulty equipment

3.5 Progressively isolate fault to remove likely variables from assessment using manufacturer’s diagnostic chart
