Version 1.0
Issue Date: April 2024


Broadcast technicians or technologists apply the skills and knowledge described in this unit. Although they work under the direction of a senior technologist or broadcast engineer, they are expected to work with minimum supervision and may, on occasions, be responsible for supervising others.

This unit covers the maintenance of equipment in both television and radio studios. The scope of work varies from working with a single piece of equipment to maintenance of a whole studio or facility, including outside broadcast vehicles.

Skills associated with the installation of equipment and facilities are covered in:

CUFBRT401A Install or upgrade broadcasting equipment and facilities.

Note: To meet the requirements of this unit, candidates need to demonstrate competency in the maintenance of facilities and equipment for either television or radio. The Required Skills and Knowledge section should be tailored accordingly.

This unit describes the skills and knowledge required to diagnose faults in and repair radio or television broadcasting facilities and equipment.

No licensing, legislative, regulatory or certification requirements apply to this unit at the time of endorsement.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)
