Elements and Performance Criteria

1. Undertake maintenance checks and routine tests
   • Electronic equipment, functions are determined and understood by reference to circuit diagrams, equipment manuals and/or consultation with equipment operator where appropriate.
   • Equipment built-in test functions are run and results are recorded to standard operating procedures where appropriate.
   • Built-in faults/status display is noted and recorded to standard operating procedures.
   • Equipment/sub-assemblies, components, connections, terminations etc. are checked visually and with correct and appropriate test equipment and techniques.
   • Faulty components are removed and replaced where appropriate.
   • All results are checked for compliance with manufacturers' requirements or specification, and results are recorded to standard operating procedures.
2. Maintain and/or service electronic equipment
   • Where appropriate, sub-assemblies are isolated according to standard operating procedures.
   • Electronic equipment/sub-assemblies are adjusted to specifications, manufacturers' requirements and/or standard operating procedures using correct and appropriate techniques, tools and test equipment.
3. Return electronic equipment to service
   • Equipment/sub-assemblies are returned into service utilising correct and appropriate techniques and procedures.
   • Equipment/sub-assemblies are checked for operational compliance to specifications and/or manufacturers' requirements, and documentation requirements are carried out to standard operating procedures.

Evidence Required

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package
Overview of assessment	A person who demonstrates competency in this unit must be able to maintainservice analogdigital electronic equipment Competency in this unit cannot be claimed until all prerequisites have been satisfied
Critical aspects for assessment and evidence required to demonstrate competency in this unit	Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria including required knowledge and be capable of applying the competency in new and different situations and contexts
Context of and specific resources for assessment	This unit may be assessed on the job off the job or a combination of both on and off the job Where assessment occurs off the job that is the candidate is not in productive work then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team The assessment environment should not disadvantage the candidate This unit could be assessed in conjunction with any other units addressing the safety quality communication materials handling recording and reporting associated with maintainingservicing analogdigital electronic equipment or other units requiring the exercise of the skills and knowledge covered by this unit
Method of assessment	Assessors should gather a range of evidence that is valid sufficient current and authentic Evidence can be gathered through a variety of ways including direct observation supervisors reports project work samples and questioning Questioning techniques should not require language literacy and numeracy skills beyond those required in this unit of competency The candidate must have access to all tools equipment materials and documentation required The candidate must be permitted to refer to any relevant workplace procedures product and manufacturing specifications codes standards manuals and reference materials
