Elements and Performance Criteria

1. Prepare to repair audio components
   • Work health and safety (WHS)/occupational health and safety (OHS) requirements and workplace procedures for relevant work area are identified, obtained and applied
2. Risk control measures are applied in accordance with workplace procedures prior to commencing work
3. Nature of the fault is obtained from documentation or from relevant person/s to determine scope of work
4. Instructions for coordinating work with others are obtained from relevant person/s and applied
5. Materials required for work are determined in accordance with workplace procedures
6. Tools, equipment and testing devices required for work are obtained in accordance with workplace procedures and checked for correct operation and safety
7. Find and repair faults
   • Workplace risk control measures and procedures are applied
8. Need to test and measure live work is determined in accordance with WHS/OHS requirements and workplace procedures
9. Apparatus is checked and isolated, as required, in accordance with WHS/OHS requirements and workplace procedures
10. Fault finding is approached methodically applying principles of audio components and circuits using measured and calculated values of apparatus parameters and/or with reference to manufacturer service manuals
11. Apparatus components are dismantled, where necessary, and parts stored to protect against loss or damage
12. Faulty components are rechecked and their fault status confirmed
13. Repairs are made in accordance with manufacturer instructions and approval of relevant person/s
14. Apparatus is reassembled and tested for safety and functionality in preparation for return to the customer
15. Unplanned situations are dealt with safely and with the approval of relevant person/s
