Technicians working with audio visual equipment in the screen, media and entertainment industries typically apply the skills and knowledge described in this unit. Under the supervision of senior technical staff, they are responsible for basic repairs and maintenance of equipment and facilities needed for a wide range of productions.

Complex repairs requiring specific mechanical, electrical or electronic skills are referred to specialist service technicians.

This unit has linkages to a range of other vision systems units, and combined training and/or assessment with those units would be appropriate, e.g.:

CUEAUD02C Prepare, rig, test and modify vision systems

CUEAUD03C Operate vision systems.

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

Critical aspects for assessment and evidence required to demonstrate competency in this unit

The following evidence is critical to the judgement of competence in this unit:

ability to correctly use repair and maintenance techniques on multiple pieces of vision systems

correct selection and use of tools

application of logical fault detection procedures

correct interpretation of service and technical manuals

knowledge of occupational health and safety principles, issues in relation to the major types of vision systems.

Context of and specific resources for assessment

The assessment context must provide for:

demonstration of skills within an environment which has a range of operational equipment on which the candidate can work, including sound, lighting and projection items

completion of fault detection, repair and maintenance tasks within typical workplace time constraints.

Method of assessment

Assessment may incorporate a range of methods to assess practical skills and the application of essential underpinning knowledge, and might include:

direct observation of maintenance and repair tasks conducted by the candidate

inspection of items repaired or maintained by the candidate

review of repair reports prepared by the candidate

written or oral questioning to test knowledge of typical vision systems and occupational health and safety issues and regulations

review of portfolios of evidence and third party workplace reports of on-the job performance by the candidate.

Assessment methods should closely reflect workplace demands and the needs of particular groups (e.g. people with disabilities, and people who may have literacy or numeracy difficulties such as speakers of languages other than English, remote communities and those with interrupted schooling).

Guidance information for assessment

Assessment of this unit requires access to:

a range of industry current vision systems

a venue where maintenance and repairs can be completed

the tools required to complete repair and maintenance tasks.
